When measuring vibration by means of an accelerometer it is
necessary to incorporate a preamplifier between this and the
measuring Amplifier. The preamplifier is introduced in the
measuring circuit for two reasons:
1) to amplify the relatively weak output signal from the
accelerometer and 2) to transform the high output impedance
of the accelerometer into a lower value. The signal from the
piezoelectric accelerometer appears as a voltage across a
capacitive impedance. This charge is proportional to the
acceleration to which the accelerometer is exposed.
