• Seismic Geophone Sensor

Perfect for all of your 2-D & 3-D seismic exploration needs with bandwidth from 10 Hz up to 240 Hz

Basically, it's a super low frequency microphone for the ground. Low distortion, combined with excellent specifications, provide high-fidelity data. A geophone works by translating ground movement into voltage, which can easily be read by a microcontroller. The geophone element is designed to offer the highest performance in seismic earthquake exploration based upon field-proven I/O Sensor technology. 


Features:

  • Tight specification, low-distortion geophone
  • Extended spurious over 240 Hz, allowing full bandwidth at 2-ms sampling
  • Sensitivity of 28.8 V/m/s
