The S-100 is a three-component velocity equivalent output seismic sensor.
The unit is recommended for local and regional seismicity and microseismicity monitoring. The design is based on the force-balance principle, Using three geophone elements, the bandwidth is extended to lower frequency of the original geophone’s natural frequency.
Actually three generations of the S-100 sensor have been implemented. Several low and upper corner frequencies provided through different senor configuration. Thus 10s, 5s, 2s and 1s low cut frequency corner is available as well as 50, 80 and 98 Hz high cut frequency corner. The sensitivity is 1000V/m/sec for the Mk1 version while it has been increased to 1500V/m/sec for the Mk2 and Mk3 version.
