Authors: Wei Ding Abstract: Low frequency performance of geophone is important when using microtremor system to explore deep geological structure. This paper reports on improving low ... WebLike an accelerometer, the geophone is a resonant device, but this time, the resonance is low frequency due to the mass (magnet) being suspended. Typically, this is around 3-4Hz, and the usable linear range is above this. This potentially gives an issue with measuring low-frequency vibration – we are often interested in measuring vibration at ...
