Triaxial Geophone 2Hz is an ideal instrument for the 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.
