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 />
elaboration software.<br />
300, 400, 500ms<br />
