ULTRA SOUNDS

ULTRA SOUNDS<br />
› CONTACT ULTRA-SOUND SURVEYS<br />
(Direct – Indirect – Semi-direct method)<br />
The method is based on the propagation<br />
speed of longitudinal ultra-sonic<br />
waves inside a reinforced concrete<br />
structure. The propagation speeds depends<br />
on the characteristics of the material<br />
such as elasticity, density, presence<br />
of gaps, micro-holes, etc… From<br />
the determination of the following parameters:<br />
reflection, refraction, transit<br />
time (T.O.F.) and mitigation of the vibration<br />
energy, it is possible to obtain information<br />
on:<br />
• Homogeneity of the mix<br />
• Elasto-mechanical characteristics<br />
• Entity, geometry and location of particular<br />
faults or internal defects, variations<br />
in time of the quality parameters<br />
of the concrete<br />
Ultra-sonic tests through which it is<br />
possible to evaluate the transit speed<br />
of the pulses (with known thickness<br />
and time) are particularly important.<br />
The primary goal of the Ultra-sound<br />
survey is to record the time of fly (TOF,<br />
Time of Fly) and the following calculation<br />
of the speed. In order to calculate<br />
the propagation speed of longitudinal<br />
waves (P waves), the arrival of the first<br />
wave-train must be found out with accuracy.<br />
In order to perform this operation<br />
correctly, the instrument must be<br />
equipped with oscilloscope that allows<br />
to visualize the transit wave on the device<br />
display.<br />
The ultra-sound tests can be carried<br />
out with:<br />
• Direct method<br />
When the transmitting and receiving<br />
probes are positioned on the opposite<br />
sides of the element to test.<br />
• Semi-direct method<br />
When the E/R probes are positioned on<br />
adjacent surfaces, usually orthogonal,<br />
of the element to test<br />
• Indirect method<br />
When E/R probes are positioned in the<br />
same side of the structural element to<br />
test.<br />
› CROSS-HOLE ULTRA-SOUND TEST<br />
The cross-hole is a method to analyze<br />
the foundation poles of buildings that,<br />
with the use of ultra-sounds, crosshole,<br />
allow to carry out an accurate<br />
high resolution test. An ultra-sonic<br />
wave is sent from a transmitter to<br />
a receiver, which are convoyed automatically<br />
by the device along the entire<br />
length of the pole inside the pipes<br />
embedded inside of it, during casting.<br />
The speed of the sonic wave and its<br />
energy are strongly influenced by the<br />
quality of the cement. Therefore, it is<br />
possible to assess the characteristics<br />
and give a tomographic representation<br />
in 2D and 3D called diagraphy..
› Mae 9<br />
› SONIC TEST ON MASONRY<br />
The principle of the sonic tests on masonry<br />
is the same as principle of ultrasound<br />
tests on concrete. The only difference<br />
is the method to produce the<br />
longitudinal elastic wave used for the<br />
measurement: a hammer is used instead<br />
of an ultra-sonic pulse. The frequencies<br />
thus produced (a few hundreds<br />
of Hz), lower than those of the<br />
ultra-sounds (a few tens of KHz) are<br />
able to also cross scarcely compact<br />
masonry walls, such as brick-faced<br />
or brick walls, thus allowing to evaluate<br />
the conservation state, through<br />
the speed and/or mitigation values of<br />
the wave produced. This type of test<br />
can also be applied on concrete structures,<br />
which sizes do not allow to use<br />
ultra-sounds, because these can no<br />
longer be measured at a few metres<br />
from the source. The sonic tests give<br />
less accurate values compared to the<br />
tests with ultra-sounds, but they can<br />
be performed also on scarcely compact<br />
materials and/or at a distance of<br />
a few metres.<br />
› PILE INTEGRITY TEST<br />
The sonic echo test is a survey method<br />
consisting in the measurement<br />
of the reflection speed of compression<br />
waves, to assess the integrity of<br />
a pole. The method was conceived in<br />
Holland during the 70s, as instrument<br />
to check the quality of pre-fabricated<br />
foundation poles in concrete, extensively<br />
used in that country. Due to the<br />
regularity of the surfaces of the prefabricated<br />
poles, the sonic echo test<br />
could be used with a high level of reliability.<br />
For this type of test, a compression<br />
wave is propagated until the base<br />
of the pole and is reflected towards its<br />
head. The compression wave is generated<br />
with an impact on the pole head<br />
and the signal recorded by a geophone<br />
is displayed in a graph in real time. If<br />
discontinuities are present in the pole<br />
such as variations of the section or<br />
cracks, these cause reflections. If the<br />
discontinuities are fairly significant,<br />
such as for example a complete fracture<br />
of the concrete, these cause an<br />
almost complete fracture, thus preventing<br />
to detect the base of the pole.<br />
In order to execute the test properly,<br />
the pole head must be accessed. The<br />
geophone is placed on the concrete<br />
surfaced, properly prepared, through<br />
a coupling material and by placing<br />
on top a load of a few kg. When the<br />
head of the pole is hit in a selected<br />
point, the impact enables the acquisition<br />
of the signal produced by the geophone,<br />
which is shown immediately on<br />
the screen. In order to eliminate the<br />
background noise caused from the<br />
construction site activities, the acquisition<br />
can be repeated a few times to<br />
calculate the averages.

Ultrasonic contact test<br />
Digital instrumentation for ultrasonic<br />
tests through transparency, it can<br />
be used for testing walls, trusses,<br />
partition walls, specimen, laboratory<br />
samples, and other types of concrete<br />
structures or stony materials.<br />
The extremely compact sizes render<br />
I-SONIC suitable for particularly burdensome<br />
uses, where utmost accuracy<br />
in the measurement is required,<br />
together with reliability, sturdiness<br />
and compact sizes. Thanks to the<br />
presence of a large graphic display,<br />
the visualization and interpretation<br />
of the data acquired is easy and immediate.<br />
Each single wave emitted<br />
by the internal generator is visualized<br />
in full and it is also possible to<br />
modify the visualization parameters<br />
to further facilitate the reading of<br />
the crossing speed. The data is saved<br />
on a removable S.D. memory.<br />
The ultrasonic test through contact<br />
is a standardized system in the diagnostics<br />
sector of concrete structures.<br />
From the analysis of the compression<br />
waves P in the material, it is possible<br />
to obtain the transit time (airborne<br />
time T.O.F.), of the ultrasonic waves<br />
in the material and the transmission<br />
speed of the same waves inside the<br />
material tested. The use of this method<br />
at high frequencies is particularly<br />
suitable for compact materials, as<br />
hardened concrete, and on structural<br />
elements of reduced sizes, such as<br />
beams, pillars, etc…<br />
This series of instruments allows to<br />
assess the mechanical characteristics<br />
of the materials, evaluate the<br />
degree of homogeneity and possible<br />
presence of holes, gaps, defects or<br />
building anomalies of the element.<br />

Instrumentation for the execution of<br />
non-invasive surveys of sonic and ultrasonic<br />
type with an electro-mechanical<br />
hammer operating on concrete structures,<br />
masonry and on various types<br />
of building materials on site and in the<br />
laboratory. The extensive spectrum of<br />
incoming frequencies analysed, allows<br />
to take measurements on materials<br />
with different mechanical, compactness<br />
and homogeneity characteristics.<br />
The ultrasonic test through transparency<br />
is a standardized system in the<br />
diagnostics sector of concrete structures.<br />
From the analysis of the compression<br />
waves P in the material, it<br />
is possible to obtain the transit time<br />
(airborne time T.O.F.) of the ultrasonic<br />
waves in the material and the transmission<br />
speed of the same waves inside<br />
the material tested. The use of<br />
this method at high frequencies is<br />
particularly suitable for compact materials,<br />
as hardened concrete and on<br />
structural elements such as trusses,<br />
partition walls, or other types of<br />
concrete structures or stony materials<br />
with good aggregation degree.<br />
The sonic surveys are carried out using<br />
an electro-mechanical hammer<br />
that acts as trigger and a receiving<br />
probe. Waves on the material to inspect<br />
are generated on the trigger<br />
hammer, which are then detected by<br />
the receiving probe and recorded in<br />
the central unit. The sonic method is<br />
extensively used in tests of materials<br />
with scarce propagation characteristics,<br />
non-compact and heterogeneous<br />
materials in which the distances to<br />
travel are fairly high and they cannot<br />
be reached with the ultra-sonic system<br />
at other frequencies. A5000UM<br />
allows to assess the mechanical characteristics<br />
of the materials, evaluate<br />
the degree of homogeneity and possible<br />
presence of holes, gaps, defects<br />
or building anomalies of the element.<br />
Masonry structures, brick-faced walls,<br />
historic and monumental buildings<br />
can be assessed in terms of conservation<br />
state, in a quick and easy manner,<br />
limiting as much as possible the execution<br />
of destructive tests. Thanks to<br />
the presence of a large graphic display,<br />
the visualization and interpretation of<br />
the ultra-sonic waves generated is<br />
easy and immediate, the first reading<br />
can be picked and the speed and quality<br />
values of the material tested can<br />
be read directly on the device display.<br />
Each single wave emitted by the internal<br />
generator is visualized in full and<br />
it is also possible to modify the visualization<br />
parameters to further facilitate<br />
the reading of the crossing speed.<br />
The data is saved on a removable S.D.<br />
memory.<br />

A3000U device is a complete system<br />
for non-destructive structural<br />
inspections through ultra-sounds on<br />
poles, deep foundations, infrastructural<br />
works or buildings. The system<br />
consists of a computerised central<br />
unit of extremely compact sizes,<br />
to which it is possible to connect, according<br />
to the type of survey, transducers<br />
for surveys in direct contact or<br />
motorised reels controlled electronically,<br />
on which probes are assembled<br />
with drilling power, for cross-holes<br />
surveys. The central unit integrates<br />
the ultra-sound generator, 2 acquisition<br />
channels, the control electronics<br />
for the automatic management of<br />
the probes when being raised/lowered<br />
in the probing tubes in the cross-hole<br />
test and for saving the data on internal<br />
or external memory of USB type.<br />
Thanks to the user-friendly management<br />
software, all the functions are<br />
selected through menus that can be<br />
browsed simply, by touching the large<br />
transflective 6.4” touch screen LCD<br />
monitor. In CROSS-HOLE surveys on<br />
concrete poles, in order to obtain the<br />
proper measurement of the crossing<br />
delay of the wave and for the optimal<br />
receipt of the signal, the probes must<br />
be perfectly aligned when taking the<br />
measurement. Thanks to the management<br />
through micro-processor,<br />
A3000U is able to ensure the constant<br />
alignment between probes when taking<br />
the measurement, and in case the<br />
alignment is not achieved, it compensates<br />
the speed between the same<br />
probes. The device carries out an ongoing<br />
testing cycle of the alignment<br />
of the probes when being lowered and<br />
raised inside the holes. This procedure<br />
allows to obtain the maximum resolution<br />
during the acquisition phase.<br />
The data acquired at each single pulse<br />
is displayed in real time on the large<br />
colour monitor, allowing an immediate<br />
visualization of possible imperfections<br />
in the structure inspected.<br />
The procedure to carry out cross-hole<br />
surveys with 2 channels is managed<br />
by A3000U central unit in automatic<br />
mode. The only operations required<br />
to the operator consist in positioning<br />
the encoders for reading the position<br />
of the motorised probes on the tubes<br />
envisaged for probing and to initially<br />
align the probes on the pole head. At<br />
this point, the data acquisition is enabled<br />
by pressing a button, it is managed<br />
in automatic mode by the central<br />
unit, and the data can be checked<br />
as soon as it is acquired. Once the test<br />
is concluded, it is possible to print immediately<br />
the test report containing<br />
the data of the probing directly in the<br />
construction site. Using the contact<br />
transducers (supplied), it is possible<br />
to use the equipment in transparency<br />
tests of walls, trusses, partition walls<br />
or other infrastructural works that require<br />
direct surveys or as laboratory<br />
analyser to check specimen, concrete<br />
samples, rock, stony or plastic materials.<br />
With the direct analysis method, it<br />
is possible to fully analyze each wave<br />
generated. The instrument can be integrated<br />
with:<br />
- expansion Kit for sonic test on walls<br />
with electro-mechanical hammer<br />
- expansion Kit for I.T. TEST (eco-ranging<br />
test) on foundation poles<br />
- expansion Kit for sonic logging on<br />

saving the data on internal or external<br />
memory of USB type. Thanks to the<br />
user-friendly management software,<br />
all the functions are selected through<br />
menus that can be browsed simply, by<br />
touching the large transflective 10.4”<br />
touch screen LCD monitor. Using the<br />
contact transducers (supplied), it is<br />
possible to use the equipment to test<br />
walls, trusses, partition walls or other<br />
infrastructural works that require direct<br />
surveys or as laboratory analyser<br />
to check specimen, laboratory samples,<br />
rock, stony or plastic materials.<br />
Thanks to the presence of the colourdisplay,<br />
the visualization and interpretation<br />
of the data acquired is easy<br />
and immediate. In the direct analysis<br />
mode, each wave emitted by the internal<br />
generator is visualized in full, and<br />
it is also possible to modify the visualization<br />
parameters to further facilitate<br />
the reading of the crossing speed<br />
and possible presence of defects in<br />
the material inspected. With the use<br />
of 3 probes with simultaneous automatic<br />
operation, A6000U device allows<br />
to save 1/3 of the time needed<br />
for probing, since three relative sections<br />
can be obtained with one single<br />
rising/lowering operation of the<br />
probes in the pole to test (which must<br />
be tested with 3 tubes). The system<br />
carries out an ongoing testing cycle<br />
of the alignment of the probes when<br />
being lowered and raised inside the<br />
holes. The data acquired at each single<br />
pulse is displayed in real time on<br />
the large monitor, allowing an immediate<br />
visualization of possible imperfections<br />
in the structure inspected. The<br />
procedure to carry out cross-hole surveys<br />
with 2 or 3 channels is managed<br />
by A6000/U central unit in automatic<br />
mode. The only operations required<br />
to the operator consist in positioning<br />
the encoders for reading the position<br />
of the motorised probes on the tubes<br />
envisaged for probing and to initially<br />
align the probes on the pole head.<br />
Once this operation has been completed,<br />
the data is acquired by pressing<br />
a button and managed in automatic<br />
mode by the central unit. It is<br />
possible to check the data when acquired,<br />
so as to assess the trend of the<br />
test in real time. It is possible to print<br />
immediately the test reports containing<br />
the data of the probing just carried<br />
out in the construction site.<br />

› WIN-SONIC<br />
The ultrasound survey on contact is a standardized system in the concrete<br />
structure diagnostics sector, making use of a transmitter probe<br />
and a receiver: through an analysis of the compression (P) waves in the<br />
material, the transit time (T.O.F. time of flight) is obtained for the ultrasound<br />
waves in the material, the distance is noted and the transmission<br />
speed is displayed. This method, at high frequencies, is therefore<br />
specifically used for compact materials such as hardened concrete or<br />
small-size structural elements like beams, pillars, etc.<br />
WIN SONIC reporting software allows the display and in-depth analysis<br />
of individual wave forms acquired, with the aim of creating a customized<br />
report of the measurements carried out.<br />
A comparison of several wave forms can also be carried out simultaneously.<br />
The software is suitable for reporting data of surveys carried out with<br />
ultrasounds in contact or sonic tests on masonry.<br />

SEISMIC<br />
EXPLORATIONS<br />
› SEISMIC EXPLORATION OF REFRACTION TYPE<br />
The seismic exploration of refraction<br />
type is among the most diffused and<br />
used active seismic methods. This<br />
type of survey has the purpose to determine<br />
the thickness of the overburdens<br />
(aerated) above a rigid sub-layer<br />
and reconstruct a seismic stratigraphic<br />
sequence in terms of apparent longitudinal<br />
speed. If carried out according<br />
to more sophisticated calculation<br />
methods, it can be used to intercept,<br />
measure and characterize geo-structural<br />
profiles. Seismic exploration of<br />
refraction type is carried out by placing<br />
equidistant geophones in line on<br />
the ground, and generating seismic<br />
pulses through mechanical “inputs”.<br />
Then the travelling times of the pulses<br />
that once penetrated in the ground<br />
are refracted nearby the lithological<br />
passages at different density, will be<br />
measured.<br />
› SEISMIC EXPLORATION OF REFLECTION TYPE<br />
The seismic exploration of reflection<br />
type, which is extensively used in oil<br />
explorations, is also used nowadays<br />
to obtain detailed information on surface<br />
soils. Due to the high resolution<br />
of the survey, it is used to define the<br />
development of geological structures<br />
in the sub-soil, defining the shapes,<br />
sizes and positions. The prospecting<br />
is carried out by placing high frequency<br />
geophones in line and close to each<br />
other, sending seismic pulses through<br />
energy (also at high frequency) and<br />
by measuring the travelling times of<br />
the waves that, once penetrated in<br />
the ground, are reflected by the uneven<br />
surfaces that delimit the lithological<br />
passages with net impedance<br />
contrast.
› Mae 25<br />
› TOMOGRAPHIC SEISMIC EXPLORATION<br />
This survey method is used to identify<br />
physical-geometrical anomalies of the<br />
sub-soil with a definitely higher resolution<br />
compared to the other seismic<br />
exploring methods, giving the opportunity<br />
to create an image of the subsoil<br />
containing all the anomalies, even<br />
the most complex ones, which cannot<br />
be resolved with other methods.<br />
In particular, the tomographic method<br />
allows to reconstruct the geometric<br />
distribution of the elements that<br />
constitute a specific section, starting<br />
from the analysis of the behaviour of<br />
the radiations that cross it.<br />
› DOWN-HOLE SEISMIC EXPLORING<br />
This type of survey is performed for<br />
the mechanical characterisations of<br />
grounds crossed during the probing<br />
phase. The technique consists<br />
in the measurement of the travelling<br />
times of the elastic waves between<br />
the seismic source on the<br />
surface and the geophones located<br />
inside the probing hole, properly conditioned<br />
with PVC pipe or geo-technical<br />
pipe. The seismic exploring activity<br />
in the down-hole takes place by<br />
placing one or more triplets of sensors<br />
(horizontal and vertical) inside<br />
one of the probing holes and at various<br />
depths, aimed at receiving the<br />
seismic signals generated through<br />
ram on anchored plate. Energy will<br />
be supplied in phase inversion in order<br />
to polarise phases S on a horizontal<br />
plane H, according to an orientation<br />
of 180°. Through seismic speeds<br />
Vp and Vs, it is possible to obtain information,<br />
such as elastic modules<br />
and geo-seismic parameters. Vs 30<br />
can be measured on probing holes<br />
up to 30 metres of depth (O.P.C.M<br />
3274/2003).<br />
› CROSS-HOLE SEISMIC EXPLORING<br />
This type of survey is performed<br />
through the physical –dynamic characterisation<br />
of the portion of ground<br />
between the two probing holes. The<br />
technique consists in the measurement<br />
of the travelling times of the elastic<br />
waves between the source located<br />
in a hole and the geophone/s located<br />
in another hole/s at the same depth.<br />
The cross-hole is made by introducing<br />
the borehole in one of the holes<br />
and the tridimensional geophone (or<br />
geophones) in another hole/s aimed at<br />
receiving the seismic signal incoming<br />
from the source at the same level. The<br />
elastic modules and mitigations of the<br />
medium between the holes can be obtained<br />
from this test.

› M.A.S.W. (Multichannel Analysis of Surface Waves)<br />
The MASW (Multichannel Analysis of<br />
Surface Waves) technique has the objective<br />
to identify variation profiles<br />
with the depth of the speeds of volume<br />
waves (Vp and Vs). The method<br />
is based on the known relations between<br />
these speeds and the dispersion<br />
of surface (or Rayleigh) waves<br />
observed when propagating through<br />
a stratified elastic medium. The analysis<br />
can be based on signals produced<br />
with a borehole on site by acquisition<br />
device (with a ram or explosion), or on<br />
the recording of the vibrations produced<br />
by far away sources (rives, industrial<br />
activities, traffic, etc).<br />
In the first case, we are talking about<br />
active MASW, with which it is possible<br />
to explore a few tens of metres of<br />
sub-soil, and in the second case, we<br />
are talking about passive MASW, that<br />
allows to reach greater depths, in particular<br />
conditions.<br />
Passive MA.S.W. is used with the purpose<br />
to obtain a speed profile 1D of<br />
the elastic waves of cut S. The technique<br />
consists in the recording of the<br />
“seismic noise” in temporal windows<br />
and following study of the signal<br />
processed. It is carried out by arranging<br />
a bidimensional geophonic chain<br />
with low resonant frequency in line<br />
or in “array” (circular and irregular geometries)<br />
and measuring the environmental<br />
noise. From the F-K analysis<br />
(frequency-space) of the wave-trains,<br />
it is possible to obtain a dispersion<br />
curve of surface waves that leads<br />
to the calculation of the speed profile<br />
of the shear waves and estimate<br />
of a coverage in relation to the semispace.<br />
› S.A.S.W. (Spectral Analysis of Surface Waves)<br />
The Spectral analysis of Surface Waves<br />
SASW allows to determine the speed<br />
profile of the shear waves of a particular<br />
ground. The method is based on<br />
the use of the dispersive properties<br />
of surface waves (Rayleigh) generated<br />
by a surface impulsive input. The<br />
depths explored vary from a few centimetres<br />
(road floors) to a few tens of<br />
metres. SASW is carried out by placing<br />
2 geophones in line, in the ground,<br />
with oscillation frequency from 14<br />
to 1 Hz, and registering the seismograms.<br />
The speeds profile of waves Vs<br />
is obtained from studying the phase<br />
speeds of Rayleigh waves. The data<br />
elaboration consists in determining<br />
the Coherence function, the Cross<br />
Power Spectrum phase and the construction<br />
of the dispersion curves<br />
of the Speed during the experimental<br />
phase in depth. In conclusion, the<br />
propagation phenomenon of the surface<br />
waves is simulated with the purpose<br />
to identify the rigidity profile<br />
reproduced by the experimental dispersion<br />
curve.

› PASSIVE SEISMIC – EXPLORATION FOR THE EVALUATION OF THE<br />
LOCAL SEISMIC RESPONSE – MICRO EARTHQUAKES<br />
This technique is used to obtain information<br />
concerning possible dynamic from the convolution of the frequen-<br />
the study of the spectrums obtained<br />
amplification effects of seismic waves cy of the signal recorded in the domain<br />
for the three components of the<br />
in “ emersion ”. It is based on the recording<br />
of the background noise in ground motion and the application<br />
the time domain and following elaboration<br />
of the signal’s frequencies in (H/V), allows to define and measure<br />
of techniques on spectrum analysis<br />
the domain. It is carried out by placing<br />
a tridimensional geophone on the and the seismic frequency of the<br />
possible local seismic amplifications<br />
ground with low frequency response site. The measurements of the microearthquake<br />
can also be taken in linear<br />
and by recording the seismic noise in<br />
different temporal windows. Later on, “arrays” for the localization of faults.<br />
› NAKAMURA METHOD<br />
A significant part of the damages observed<br />
in destructive earthquakes all<br />
over the world is associated with the<br />
amplification of seismic waves due to<br />
the effects of the local site. The analysis<br />
of the site response is therefore essential<br />
in the evaluation of the seismic<br />
risk in areas subject to earthquakes.<br />
In order to evaluate the effects of the<br />
local site, a series of surveys must be<br />
carried out. Among the empiric methods,<br />
the method of spectrum analyses<br />
H/V on environmental vibrations is<br />
one of the most common. The method,<br />
also called “Nakamura” technique<br />
(Nakamura, 1989), was introduced by<br />
Nogoshi and Igarashi (1971) based on<br />
the initial studies of Kanai and Tanaka<br />
(1961). Since then, many researchers<br />
worldwide performed a large number<br />
of applications.<br />
An important requirement to carry out<br />
the H/ V method consists in a fairly good<br />
knowledge of seismology combined<br />
with basic information on local geological<br />
conditions supported by geo-physical<br />
and geo-technical data. The method<br />
is generally applied in micro-zoning<br />
studies and in the analysis of the local<br />
response of specific sites.<br />
› SEISMIC MONITORING<br />
Seismic monitoring is carried out in areas<br />
subject to risks related to a seismogenic<br />
activity, by acquiring the<br />
seisms with time and recording the<br />
seismograms. Seismic stations are<br />
used able to record in threshold or<br />
continuous type, and low frequency<br />
geophones or seismic accelerometers.<br />
The recording in the long period,<br />
of the earthquakes relative to a<br />
site or fairly large area allows to configure<br />
the seismic scenario of an area<br />
and evaluate the risk and vulnerability<br />
conditions. If the monitoring activity<br />
is supported by specific knowledge<br />
of geological and geo-technical<br />
type, we are talking about seismic Micro-zoning.

of the seismograph (SST technology).<br />
The adoption of this architecture<br />
renders A6000S ideal for all types of<br />
active and passive seismic prospecting,<br />
and for structural surveys and inspections<br />
on buildings and infrastructural<br />
works (acquisition of vibrations<br />
with accelerometers or low frequency<br />
seismic sensors, tomographic surveys,<br />
etc).<br />
Thanks to the great versatility and<br />
numerous automatic, pre-acquisition<br />
checking procedures, from the proper<br />
connection of the geophones to the<br />
analysis of the noise relative to the<br />
site inspected, the data acquisition<br />
is always particularly easy to handle<br />
by anybody. It is also possible to carry<br />
out a first analysis of the data acquired,<br />
also for single wave, directly<br />
on site, visualizing the seismograms<br />
in details, with just a few simple operations.<br />
The data is saved on an internal,<br />
solid state hard disk, for better<br />
protection in case of collisions, or<br />
on an external USB memory.<br />

Seismic vibration monitoring<br />
Nakamura method<br />
24-bit seismograph for passive seismic<br />
exploring, particularly suitable<br />
for monitoring seismic vibrations in<br />
buildings and infra-structural works,<br />
for dynamic studies of the structures<br />
or seismic monitoring of ground areas.<br />
A5000SP is an independent station<br />
for the detection and recording<br />
of seismic events in automatic<br />
mode. The data acquisition methods<br />
(timed or with trigger threshold) are<br />
set through the software easily and<br />
quickly. Equipped with graphic display,<br />
keyboard, memory support of<br />
Secure Digital (S.D.) type and internal<br />
battery, A5000SP seismograph<br />
is particularly easy to use also in extreme<br />
environments and conditions.<br />
Using the kit for long-term installations,<br />
with external battery and solar<br />
panel, available upon request, it<br />
is possible to carry out ongoing seismic<br />
monitoring activities in a simple<br />
and quick manner, also in remote areas<br />
without electric power. It is also<br />
possible to equip the instrument<br />
with integrated GSM module to connect<br />
online from a remote station and<br />
download the data contained in the<br />
unit. The management software also<br />
allows to manage calls or alarm messages<br />
triggered from exceeding the<br />
pre-set alarm thresholds. Thanks to<br />
the innovative architecture of MAE<br />

acquire, register and graphically visualize<br />
up to 8 analogue signals coming<br />
from seismic sensors or accelerometers<br />
(with single component or tridimensional).<br />
The high sampling resolution<br />
obtained and the elaboration<br />

SPECIFICATIONS<br />
The seismic acquisition system called SETA<br />
SYSTEM has been developed by MAE in jointventure<br />
with partners of high profile, such<br />
as: the National Institute of Oceanography<br />
and Experimental Geo-physics, OGS, located<br />
in Trieste, and the National Institute of Geophysics<br />
Georgiano, IGEM, located in Tbilisi.<br />
The system allows to create architectures<br />
for seismic networks in digital telemetry<br />
with 24-bit resolution, using the two basic<br />
units of the system or the RX-16 receiver,<br />
with 16 inlets for as many transmitting<br />
units TX-3, properly located on the territory<br />
that must be monitored. The S.E.T.A system<br />
has been developed with the purpose<br />
to create a vast territorial network of seismic<br />
monitoring stations, completely independent<br />
in terms of energy and radio communications,<br />
able to monitor the seismic/<br />
micro-seismic activity of the territorial area<br />
where it is located, 24 hours a day. The remote<br />
units are installed in suitable rural containers,<br />
which characteristics are developed<br />
based on the specifications of each system.<br />
These are usually fed by battery packs with<br />
high autonomy, re-charged through solar<br />
panels or other solutions. The digital transmitting<br />
unit TX- 3 AD is equipped with 3 inlet<br />
channels with 24-bit resolution, and allows<br />
to use velocimeters with 1/2 Hz frequencies<br />
or mono and three-axial accelerometers, in<br />
addition to geophones of different frequency.<br />
It is stored inside a sturdy steel container,<br />
it codes and transmits via radio the signals<br />
coming from the seismic sensors to<br />
the Data Collection Station, with which it is<br />
in constant connection, where one or more<br />
RX-16 units have been installed, which receive<br />
and decode the data acquired locally<br />
by the remote units. The data transmitted<br />
by the RX-16 in real time can be then treated<br />
with different types of analysis software<br />
and stored through proper procedures, thus<br />
allowing the creation of an archive of seismic<br />
events of the geographic region object of the<br />
study. The data collected allows to know and<br />
constantly monitor the seismic activity in<br />
the monitored region. The system has been<br />
conceived to work with automatic recording<br />
and signalling modes of the events that occur<br />
on all the remote stations connected to<br />
the system. The data coming from the remote<br />
stations of the network can be viewed<br />
on the terminals of the Data Collection Centre<br />
24 hours a day.<br />

› ESP - SEISMIC GAS EXPLODER WITH COMBUSTION CHAMBER<br />
The ESP2 Seismic Energizer is a source of seismic energy used to “energize” the soil to<br />
better determine the nature of the soil itself, as well as its stratigraphy, through a seismic<br />
prospection. The system operates by means of two steel cylinders that, once the detonation<br />
is triggered, move one inside the other thereby energizing the underlying soil. This gas<br />
exploder apparatus is extremely simple and safe for the operator to use since the trigger is<br />
operated by remote control. The detonation is ignited thanks to the built-in rechargeable<br />
12V battery. A bayonet clutch allows the cartridge to be replaced quickly and easily.<br />
› SEISMIC TOMOGRAPHY KIT<br />
Seismic tomography on structures is a non-destructive inspection technique which allows to<br />
create images of the investigated structures by measuring the travel-time of induced seismic<br />

SOFTWARE<br />
mae-srl.it/go/pslab<br />
› PS-LAB<br />
PSLAB allows simple processing of seismic data in SEG2 format relating<br />
to surveys for refraction or with down-hole technique. Through a<br />
guided path, the program enables a detailed report of the survey to<br />
be obtained, accompanied by graphics and tables, starting from the<br />
field data. For surface seismic analysis, identification of the depth of<br />
refractors is based on the generalized reciprocal method (GRM), which<br />
requires a minimum of three energizations along the extent and calculates<br />
the depth below each geophone and the average speeds of<br />
compression waves in the seismic layers. When identification of the first<br />
arrival times has been performed, directly on seismograms with different<br />
graphic aids or with manual entry in a table, the analysis of travel<br />
time graphs is made simple by an intuitive approach that provides for<br />
the times observed to be attributed to the different refractors by means<br />
of a simple mouse-click. For the down-hole technique, there is automatic,<br />
fast loading of all measurement files in a particular folder. Calculation<br />
of Vp and Vs speeds is based on the interval method. The program<br />
calculates the speeds and the corresponding Poisson module for<br />
each layer detected by analysis of the travel time graphs and the Vs30<br />
average for the entire log.

and the ratio between d.d.p. and<br />
the current intensity is measured<br />
from time to time. The resistivity<br />
values thus obtained are influenced<br />
by the characteristics of the materials<br />
at increasingly greater depths.<br />
In view of this second effect, a geometric<br />
correction must be made and<br />
therefore factors that depend on<br />
distances MN (measurement electrodes)<br />
and AB (input electrodes)<br />
must be introduced in the calculation<br />
of the resistivity. According to<br />
the variations of the electrodes positions<br />
along the geo-electric area,<br />
different quadrupole systems are<br />
identified: Wenner and Schlumberger.<br />
A profile 1D of the ground resistivity<br />
is obtained below one point.
› Mae 47<br />
› S.E.O. (Horizontal electric explorations)<br />
This type of survey is carried out with<br />
the purpose to obtain a resistivity profile<br />
of the ground along a direction and<br />
at a certain depth. Each unhomogeneity<br />
in the medium tested, like bodies with<br />
different electric conduction capacity,<br />
is identified because it deflects the current<br />
lines and distorts the regular distribution<br />
of the electric potential. Furthermore,<br />
by measuring the potential<br />
drop on two random points, it is possible<br />
to determine the electric resistivity<br />
of the medium by multiplying the ratio<br />
between the potential drop and the<br />
current sent by a geometric coefficient<br />
which depends on the position of the<br />
electrodes on the ground. By changing<br />
the position of the electrode device on<br />
the area to test, it is possible to determine<br />
the distribution of the resistivity<br />
in the volume subject to electric current.<br />
Since rocks are resistive materials<br />
by nature, the resistivity variations are<br />
due almost exclusively to the presence<br />
of water in different quantities. The SEO<br />
is carried out by fixing 4 electrodes in<br />
the ground, two of which (the external<br />
ones) are for anchoring purposes<br />
and the other 2 (internal ones) are for<br />
measuring purposes, at a certain distance<br />
from each other. It is possible to<br />
obtain a horizontal profile of the resistivities<br />
of the grounds, which is useful<br />
to identify a vertical passage between<br />
two bodies with different resistivity.<br />
› RESISTIVITY TOMOGRAPHIC GEO-ELECTRIC PROFILE<br />
(Electric tomography)<br />
This type of survey is based on the<br />
calculation of the resistivity from the<br />
d.d.p measurements in the ground. The<br />
method is based on the introduction of<br />
an electric field in the ground through<br />
electrodes (input or current) and the<br />
measurement of the d.d.p. in other<br />
electrodes (of measurement type).<br />
From the d.d.p. value, it will be possible<br />
to find the resistivity value through the<br />
second law of Ohm, which is a typical<br />
characteristics of all materials. Since<br />
rocks are resistive materials by nature,<br />
the resistivity variations are due almost<br />
exclusively to the presence of water in<br />
different quantities. Electric tomography<br />
2D-3D is carried out by fixing electrode<br />
grids in the ground (16, 32, 64,<br />
128….) at constant pitch. All of them<br />
are connected to boxes which allow<br />
commutation among them, defining<br />
which are the measuring and current<br />
electrodes from time to time and automatically.<br />
The system will automatically<br />
perform all possible combinations.<br />
For this purpose, a series of measurements<br />
will be obtained (as many as the<br />
combinations available), based on: the<br />
number of electrodes and type of geometric<br />
configuration used. The tomographic<br />
inversion of the data obtained<br />
on the surface generates a bidimensional<br />
or tridimensional reconstruction<br />
in “output” of the ground, from which it<br />
is possible to identify possible anomalies<br />
due to cavities, water bodies, etc,<br />
and identify shapes, sizes and spatial<br />
distribution.

› INDUCED POLARISATION<br />
The Induced Polarisation (PI) is an<br />
electric phenomenon that occurs inside<br />
of material media in the time domain,<br />
with the release of stresses upon<br />
the interruption of a flow of electric<br />
current of step type (in this case, it is<br />
measured as chargeability) and also in<br />
the frequency domain, with a precise<br />
dispersion law of the electric resistivity<br />
upon the variation of the frequency<br />
of an alternated current flow. A PI<br />
source is connected to the oxido-reductive<br />
processes along the interface<br />
between the metal grains and interstitial<br />
fluids (electrode polarisation). Another<br />
important PI source consists instead<br />
of ionic accumulations in moving<br />
electrolytes due to mobility variations<br />
along the path (electro-kinetic polarisation).<br />
The tomographic inversion of<br />
the data obtained on the surface returns<br />
the ground in “output” based on<br />
chargeability images, thanks to which<br />
it is possible to identify possible accumulation<br />
areas or significant concentrations<br />
of hydrocarbons. The chargeability<br />
is proportional to the charge<br />
stored by the lithotype and it represents<br />
the concentration of a conductor<br />
in the multi-electrode area.<br />
› SPONTANEOUS-POTENTIAL METHOD<br />
The Spontaneous Potential method<br />
(PS) consists in determining on<br />
the surface, the differences of potential<br />
related to a natural electric<br />
field, linked to the underground circulation<br />
of aqueous electrolytic solutions<br />
in porous media. From the analysis<br />
of PS anomalies in the surface, it<br />
is possible to determine the intensity<br />
and position of the concentrations<br />
of ionic charges with both polarities.<br />
The test is carried out by positioning<br />
two electrodes: the first one close to<br />
the measurement station and the other<br />
one is moved on the following stations<br />
of the line; of both electrodes<br />
are moved, by keeping stable the interval<br />
between them, mapping the<br />
ground based on the spontaneous potential.<br />
The use of this method is useful<br />
in the mining field for the search<br />
of sulphides and graphite, but also in<br />
the archaeological field, indeed water<br />
circulations can be affected by underground<br />
archaeological structures,<br />
that could act as drain or as obstacle,<br />
and therefore, with the identification<br />
of PS anomalies, it is possible in general<br />
to find underground archaeological<br />
structures indirectly.

MAE A6000SE combined instrumentation<br />
represents the most compact and<br />
versatile solution for active and passive<br />
seismic prospecting (24 channels,<br />
24 bit) and geo-electric prospecting,<br />
with quadripole (SEV) techniques or<br />
multi-electrode electric tomography.<br />
The type of seismic or geo-electric<br />
probing to carry out is selected from<br />
the main menu, by simply touching the<br />
colour, touch screen monitor. Once the<br />
data acquisition method has been set<br />
(single measurement or cycle), the<br />
data is automatically acquired by the<br />
device by simply pressing a button.<br />
The main characteristic of the seismograph<br />
section is the 24-bit resolution<br />
for each single channel. This<br />
result is achieved thanks to the adoption<br />
of a new, 24 bit, MAE data acquisition<br />
card that uses an A/D digital converter<br />
for each inlet channel of the<br />
seismograph (SST technology). The<br />
adoption of this architecture renders<br />
A6000SE ideal for all types of active<br />
and passive seismic prospecting, and<br />
for structural surveys and inspections<br />
on buildings and infrastructural works<br />
(acquisition of vibrations with accelerometers<br />
or low frequency seismic sensors,<br />
tomographic surveys). It is also<br />
possible to carry out a first analysis<br />
of the seismograms acquired, also for<br />
single wave, directly on site, visualizing<br />
the seismograms in details, with<br />
just a few simple operations.<br />
The georesistivity meter section of<br />
A6000SE is characterised by utmost<br />
resolution and accuracy in the geoelectric<br />
survey and extreme operative<br />
promptness thanks to the use of highly<br />
resistant cables for geo-electric prospecting,<br />
equipped with 16 plugs each,<br />
with intervals of 2; 3; 5 or 10 metres<br />
each. The instrument takes the measurement<br />
or carries out the measurement<br />
cycle set by the user in automatic<br />
mode; once the measurement cycle<br />
is completed, the acquired data can be<br />
immediately processed with the relative<br />

A6000E is a digital georesistivity meter<br />
for Multi-electrode Electric Tomography<br />
or S.E.V. (Sondaggio Elettrico<br />
Verticale – Vertical Electric Probing).<br />
The instrument integrates all the elements<br />
to carry out vertical geo-electric<br />
and multi-electrode prospecting<br />
with 32 electrodes. It is anyhow possible<br />
to increase the number of electrodes<br />
managed by the device through<br />
the external extension boxes of 16<br />
electrodes each, up to maximum 256<br />
electrodes. The device is characterised<br />
by utmost resolution and accuracy<br />
in the geo-electric survey and extreme<br />
operative promptness thanks<br />
to the use of highly resistant cables<br />
for geo-electric prospecting, equipped<br />
with 16 plugs each, with intervals of 2;<br />
3; 5 or 10 metres each. The instrument<br />
takes measurements or performs the<br />
measurement cycle set by the user in<br />
automatic mode. Once the measurement<br />
cycle is concluded, the acquired<br />
data can be immediately processed<br />
with the relative data elaboration software.<br />
The power supply is guaranteed<br />
by external battery packs managed by<br />
a micro-processor with extensive acquisition<br />
autonomy. The 60 Watt power<br />
of the internal generator can be increased<br />
up to 600 Watt with the use<br />
of an optional external generator. Data<br />
recording and saving take place on an<br />

MONITORING<br />
› NON-DESTRUCTIVE TESTS<br />
The Non Destructive Tests (NDT) consists<br />
in a series of assessments, tests<br />
and surveys carried out with methods<br />
that do not alter the material and do<br />
not require the destruction or removal<br />
of samples from the structure tested,<br />
aimed at finding and identifying structural<br />
defects of the same structure. The<br />
acronym NDT derived from the English<br />
expression Non Destructive Testing, is<br />
often used or acronym P.n.D., derived<br />
from Non Destructive tests (in Italian).<br />
In the industrial sector, each product<br />
of critical importance (beams for construction,<br />
support screws, aeronautical<br />
components, car components, pressure<br />
bodies) must be checked to assess<br />
its integrity and conformity with<br />
applicable laws. The primary objective<br />
of non destructive tests is therefore to<br />
foresee the cracking of materials and<br />
objects, thus covering an essential role<br />
to prevent economic damages due to<br />
possible accidents and also to guarantee<br />
a high level of safety for operators.<br />
Reinforced concrete structures<br />
(masonry), particularly important for<br />
their long-life and unlimited endurableness<br />
to continuous and uncontrollable<br />
changes, excluding disastrous<br />
events (earthquakes, thermal shocks,<br />
landslides, etc), ) in the majority of<br />
the cases showed phenomena of progressive<br />
deterioration during their life.<br />
These defects are linked to the executive<br />
phase of the works, aggressiveness<br />
of building materials (alkalis – silica<br />
reactions), micro-holes produced<br />
by water-thermal variations, sagging<br />
of foundations or grounds, static-dynamic<br />
operating stresses. The non invasive<br />
character of this method applicable<br />
to existing works allows to verify<br />
the physical and mechanical characteristics<br />
of the materials that constitute<br />
the structure.<br />
› MEASUREMENT OF HEAT TRANSMISSION ON SITE<br />
In building technology, the testing of<br />
the insulation capacity of building materials<br />
is an important topic of study. In<br />
addition to laboratory measurements<br />
of the thermal properties of materials,<br />
their behaviours is also studied through<br />
tests on field, in order to obtain information<br />
on the behaviours in different<br />
climates. The total heat flow through a<br />
material consists of a conductive, convective<br />
and radioactive part. In order to<br />
measure the heat transmission, a heat<br />
flow meter and some thermometers<br />
are used, assembled on both sides (interior<br />
and exterior) of a wall. After recording<br />
the flow and temperatures for<br />
a few hours, measured with high precision,<br />
the data is elaborated to obtain<br />
the average heat transmission of<br />
the wall.
› Mae 59<br />
› LOAD TESTS<br />
The load tests have the primary objective<br />
to compare the experimental<br />
arrows obtained during the testing<br />
phase and the theoretical arrows<br />
of the project, in order to evaluate<br />
the deformation profile of the element<br />
tested. The test loads used can<br />
be distributed (bricks, blocks or cement<br />
bags, water tanks) or similar<br />
concentrates (hydraulic jacks). The<br />
tests that use similar concentrated<br />
loads can be of pull or push test type.<br />
The result of the load tests and elastic<br />
behaviour of the structure is represented<br />
through load/shift graphs and<br />
hysteresis curves. The measurement<br />
of the shifts and deformations can be<br />
taken with manual systems, such as<br />
mechanical comparators or deflectometers<br />
or with automatic-electric<br />
systems, such as movement transducers<br />
(resistive, inductive, potenziometric).<br />
The use of these electric systems<br />
allows continuous, stable and<br />
precise readings that can be transmitted<br />
also far away from the relative<br />
testing area. Rapidity of execution, accuracy<br />
and safety make this system<br />
the most diffused one nowadays, in<br />
the test and trial sector.<br />
› MEASUREMENT OF THE HEAT TRANSMISSION IN GROUNDS<br />
The measurement method is based<br />
on the so called unstable sensor technique,<br />
that uses a probe (also called<br />
thermal needle), which mounts a heating<br />
wire and a temperature sensor. The<br />
probe is introduced in the ground. From<br />
its response when subject to a heating<br />
cycle for a few minutes, it is possible<br />
to calculate the thermal resistivity (or<br />
its opposite, the heat transmission).<br />
The principle of the measurement is<br />
based on a peculiar characteristic of<br />
a rectilinear heat course (the heating<br />
wire of the probe): after a short transitional<br />
period, the increase of the temperature<br />
depends only on the heating<br />
power and heat transmission of the<br />
medium. Once the first is known, the<br />
second can be calculated. The main<br />
applications of the technique consists<br />
in the testing of high voltage cables<br />
and heating ducts.

A5000T<br />
SUPPORTED INVESTIGATION<br />
Measure of soil thermal conductivity<br />
A5000T is a device specifically studied<br />
to measure the heat transmission of<br />
the ground (tendency of the ground to<br />
transmit heat). This type of survey is<br />
usually carried out prior to install the<br />
underground cable ducts, or prior to<br />
build the geo-thermic wells to detect<br />
the heat from the ground, for heating<br />
or conditioning buildings. The measurement<br />
can be taken on site with<br />
the probe supplied, up to a depth of<br />
120 cm, or in case of greater depths,<br />
it is possible to pick up samples of<br />
compact ground (logs) and take the<br />
measurement in the laboratory with<br />
the relative laboratory probe. The acquired<br />
data can be examined directly<br />
on site, at the end of the acquisition<br />
phase regulated automatically by<br />
the device and it is expressed graphically<br />
and numerically in watt / (metres<br />
x kelvin) where: watt = unit of power;<br />
metre = unit of distance; kelvin = unit<br />
of temperature. In operative terms,<br />
a hole is made in the ground using a<br />
common drill (not supplied) and a perforation<br />
point of 20 mm diameter with<br />
prolonged rod (supplied). Then, the<br />
probe is introduced in the hole and<br />
by pressing slightly, the point of the<br />
probe is fixed into the ground by about<br />
20 cm, with the purpose to obtain the<br />
best coupling with the ground. The<br />
data acquisition procedure is initiated<br />
by pressing a button, it is managed<br />
automatically by the instrument, and<br />
lasts a few seconds. The numeric and<br />
graphic data is stored on SD memory<br />
and then elaborated with the relative<br />
GT-LAB software supplied with the instrument.<br />

SOFTWARE<br />
› GM-LAB<br />
Software for managing measurements produced by instruments for<br />
monitoring. It facilitates data analysis thanks to the possibility of displaying<br />
graphics from different sensors. Through a simple and intuitive<br />
user interface, it is possible to manage the numerous functions of the<br />
application that allow storage of data from the monitoring concerned<br />
and the making up of test reports, professionally and quickly.<br />
Main functions:<br />
- Printable report of the data read and relative graphics, photos and indication<br />
of place of monitoring<br />
- General information on the site or structure being monitored<br />
- Type, number of sensors used and their location on the structure<br />
- Value of movements detected during the monitoring phase<br />
- Progressive systematic description of cracks through graphic displays<br />
of time diagrams<br />
- Automatic calculation of x and y movement for double measurement<br />
points<br />
The most useful feature of the GM LAB software is its multi-parametricity<br />
- that is, the possibility of managing data from many types of sensors<br />
in order to allow maximum freedom in configuring the sensor systems<br />
necessary for monitoring requirements.<br />

› GT-LAB<br />
Software for calculating CONDUCTANCE and TRANSMITTANCE.<br />
The GT Lab program enables conductance and transmittance calculations<br />
by importing data measured with a thermal flux-meter.<br />
CONDUCTANCE<br />
The conductance calculation is carried out with the progressive averages<br />
method. By this method, the conductance is obtained not by using<br />
instantaneous values for temperature and thermal flow, but by taking<br />
account of the values calculated on averages obtained from the total<br />
of the readings performed.<br />
TRANSMITTANCE<br />
The transmittance calculation is carried out by selecting the surface<br />
coefficients of heat exchange, which combine the effects of the above<br />
phenomena and are tabulated in UNI 7357/76 Regulations and subsequent<br />
adaptations according to the geometrical situation (e.g. vertical,<br />
horizontal structure, etc.), and in the UNI regulations accompanying<br />
Law 10/91 (e.g. in the UNI 10345 regulations for window elements).<br />
mae-srl.it/go/gtlab<br />
› PC-LAB<br />
Software dedicated to display and storage of data acquired during load<br />
tests on floors or other load-bearing elements carried out with M.A.E.<br />
instrumentation.<br />
The test consists of producing, on a longitudinal line of the floor, one or<br />
more concentrated forces. The forces are calculated so as to produce<br />
the same maximum state of stress laid down in the design for applying<br />
the distributed load.<br />
When receipt of data starts, the software records the measurements on<br />
entry, displays them and creates the graphics in real time.<br />
The load value can be read automatically or entered manually.<br />
The reading of the data may be continuous in real time or at manual intervals<br />
with recording of the data decided on by the user.<br />
Data and Graphics displayed in real time.<br />
Possibility of analysing the graphic for one or more channels simultaneously.<br />
Report creation with tables of measurements read and graphics generated.<br />
Accepts LAN and USB connections.<br />

› ALARM-MANAGER<br />
Software for managing alarms from monitoring stations. Receives<br />
alarms notifications by text message sent by detection units. Shows<br />
on video the list of alarms received with information such as place of installation<br />
of the station, sensor in alarm and type of alarm found. A log<br />
is also generated with all the alarms that have occurred, with recording<br />
of date, time, station of origin and sensor in alarm.<br />
The software allows programming of alarm thresholds settable by the<br />
user for each channel; when these thresholds are reached or exceeded,<br />
a call or alarm text message is sent automatically to one or more numbers<br />
entered in the station at the time of programming.<br />
