The high sensitivity velocity sensor including 3 orthogonal and 3 angular (rotational) sensitivity axes is the unique development based on the molecular-electronic technology. It provides new data channels and presents new means to retrieve more data from seismic signals.
The sensor combines the advantages of the high-sensitive molecular-electronic linear and angular motion sensors. It is the reliable fast-deploying instrument for field seismic measurements.
Applicable for the following areas: geophysics, exploration seismology, earthquake engineering, seismic monitoring of high-rise buildings, bridges and constructions.
