Triaxial Geophone 2Hz

Triaxial Geophone 2Hz is a ideal instrument for seismic survey and industrial vibration monitoring. Inside of the triaxial geophone, three mutually perpendicular 2Hz geophone elements are arranged in Cartesian coordinates, which means that the vertical geophone element is Z direction, the east direction horizontal geophone element is X direction, and the north direction horizontal geophone element is Y direction, by which the Seismic signals in the three directions of X, Y and Z will be taken simultaneously and converted into electrical signal outputs.

ST Series Triaxial Geophone 2Hz(P/N:ST-2-3D) is fully compatible with assorted seismographs to perform HVSR, MASW, Surface Waves and Vibration monitoring with the features of high sensitivity, low distortion, good consistency, good linear response, and reasonable damping coefficient.

  • Rugged structure, good sealing and excellent waterproof performance.
  • Horizontal adjustment device equipped.
  • 7-pin blocking connector is equipped to prevent sensor damage during transportation.
  • Adjusting Screws(3pcs) are supplied for using on hard surfaces and also interchanges steel spikes(3pcs) are also supplied for using on soft earth ground.
  • A connecting cable for seismograph with 10m length is supplied with a NK2721C connector, split spring connectors or free cable end optional.
  • Delivered with a carrying case.
  • Widely used in HVSR, MASW, Surface Waves and Vibration Monitoring.
