Geophone sensor is a kind of acoustic sensor with small volume, low frequency and high noise sensitivity. It has the characteristics of low acceleration sensitivity and good anti-flow noise performance.
Characteristics
Good Price Land Geophone 4.5hz Seismic Geophone Sensor for Sale 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.

A geophone is a device that converts ground movement (velocity) into voltage, which may be recorded at a recording station. The deviation of this measured voltage from the base line is called the seismic response and is analyzed for structure of the earth.
