MAE A6000SE modular combined
system is a very compact and versatile equipment for
24-channel/24-bit active and passive seismic PROSPECTIVEs, and
geoelectrical PROSPECTIVEs using both the four-terminal network
technique or the multi-electrode electrical tomography system.
The seismic or geoelectrical survey methods are easily selected from
the main menu of a touch-screen colour display. Upon choosing the
data acquisition system needed (single measurement or complete cycle),
data retrieval is automatically performed by the push of one button.
This seismograph main characteristic is the real 24-bit resolution
for each single channel; this is achieved thanks to MAE new 24-bit
data acquisition card, which uses an A/D 24-bit digital converter
for each of the seismograph entry channels. This peculiar
characteristic makes the A6000SE seismograph the ideal solution for
any active or passive seismic PROSPECTIVE, structural surveying and
inspections of buildings and infrastructure facilities (acquisition
of vibrations by accelerometers or low frequency seismic sensors,
tomographic surveys). |
