Factory Price Seismograph Sensor, Velocity Seismic Sensor, Seimic Survey Geophone are devices that convert ground motion into voltage that can be recorded at a recording station. The deviation of the measured voltage from the baseline is called the seismic response and analyzes the structure of the Earth.

2.0 Hz three-component geophone is an electromechanical changeover device (sensor). Three 2.0 Hz geophones are orthogonally arranged (a vertical and two horizontal geophones) inside a sealed case, which indicate vertically for the Z-axis, east for the X-axis and north for Y-axis respectively. It is designed to receive seismic signals simultaneously from three dimensions and convert them into electrical pulses. It has such good characters as high sensitivity, high accuracy, perfect damp factor,good consistency, solid structure, good seal and water-proof capability. There is a leveling bubble on the cover and a direction indication on the seismometer. It can be used with a deep seismograph to detect seismic activity in applications such as earthquake prediction, structural analysis, etc.
