Seismic Survey Wave Geophone Seismograph Sensor Seismic Geophone Element And Geophone String with Plug and Mueller Clip
With good consistency of parameters, firm mechanism, good sealing, each geophone signal is output separately, high sensitivity, low distortion, reasonable damping coefficient and high resolution, it can meet the requirements of multi wave component seismic data acquisition technology
Deep seismic exploration, natural earthquake prediction and monitoring, engineering micro vibration measurement, and other aspects of low-frequency vibration measurement have high sensitivity, low distortion, reasonable damping coefficient, good linear response, good water resistance, and high resolution. In order to meet the needs of different users, there are horizontal and vertical varieties.
It is widely used in petroleum, coal, metallurgy, national defense engineering and shallow seismic exploration
Seismic refraction, reflection and surface wave sensors
Seismic CT and acoustic CT

So the geophone is a kind of mechanical vibration into electrical energy conversion device. Due to the different design of various geophone, the sensitivity and frequency characteristics are also different, so the formation of different geophone models. Now the land is almost all moving coil type electromagnetic geophone, and at present, the development of digital geophone, swamp or ocean geophone used are piezoelectric type, some people will be used in the Marine seismic exploration geophone called hydrophone.
