All About Geophone and Hydrophone
A geophone is a ground motion transducer used by geophysicists and seismologists to measure seismic activity by measuring changes in electrical potential. The seismic response is defined as the amount by which this recorded voltage varies from a reference line and is used in studying the composition of the earth. The geophysical equipment for sale resonance frequency is crucial for detecting and measuring weak signals. However, geophones also need to be able to see signs at higher frequencies. Most commercially available geophones, however, are held together by mechanical springs, severely limiting the device's effectiveness. By reflecting the Geophone's output, the Geophone's sensitivity to low-frequency signals may be adjusted, making the Geophone more sensitive to specific movements. Geophone's resolution may be changed by moving the proof mass around. Theory of Operation The essential element of a geophone is a weight held in the air by mechanical springs
