Miniature Charge Amplifier for Piezoelectric Transducers

The Series 5820 Charge Amplifiers from Columbia are specifically developed for use with virtually all piezoelectric transducers to develop several airborne vibration and shock data acquisition systems. Very small package size and extremely low power consumption are the features of these devices.

Series 5820 Charge Amplifiers offer dual signal outputs, one is biased about +2.50 VDC and one unbiased capacitance and the other one is unbiased capacitance coupled. They come in seven standard charge conversion ranges. Each range provides a 10:1 tandem gain adjustment capacity. It comes with a range of seven low-pass filters to fulfill the separate vibration measurement requirements of the users.
