The C-100 Seismic Sensor

The C-100 is a three-component, velocity-equivalent output seismometer. The sensor consists of three geophone elements, one per axis. When combined with our force balance electronics (third generation), the bandwidth is extended to 10 sec – 98 Hz, and the sensitivity is increased to 1500 V/m/s.

Additional Details

The seismometer electronics are integrated into the GEOThree digitizer and provide a sensitivity of 1500 V/m/s. The default cable length is approximately 20 meters, but it can be extended up to 150 meters. A dot sign engraved on the case’s plastic cover indicates the direction of each axis. Smart elastic clamping ensures excellent coupling with the borehole at any depth. Optionally, surface mount installation is available.
