Charge amplifiers

Charge amplifiers convert charge signals from piezoelectric sensors into proportional voltage signals.

A charge amplifier is a charge converter that converts very low charge signals, such as those generated by piezoelectric sensors, into proportional voltage signals (volts). As the inventor of the charge amplifier, Kistler offers a huge range of charge amplifiers for all applications.
