Why use an Accelerometer Preamplifier? Direct loading of a piezoelectric accelerometer’s output, even by relatively high impedance loads, can greatly re- duce the accelerometer’s sensitivity as well as limit its frequency response. To minimise these effects the accel- erometer output signal is fed through a preamplifier which converts to a much lower impedance, suitable for connection to the relatively low input impedance... »
