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