Endevco 2771B-10 Remote Charge Converter
The Endevco 2771B-10 is a remote charge converter designed for use with piezoelectric accelerometers and pressure transducers. It converts the high-impedance charge output of these sensors into a low-impedance voltage signal, suitable for transmission over long cables to data acquisition systems or signal analyzers. This model offers a charge sensitivity of 10 pC/mV, providing excellent signal-to-noise ratio and minimizing signal degradation due to cable capacitance.

This unit
The Endevco 2771B-10 is a remote charge converter that transforms high-impedance charge output from piezoelectric accelerometers and pressure transducers into a low-impedance voltage signal suitable for extended cable transmission. This two-wire, single-ended in-line charge amplifier operates within a constant current range of 4 mA to 20 mA and delivers a fixed gain of 10 mV/pC. The low-impedance output minimizes noise pick-up and eliminates susceptibility to cable shunt capacitance, enabling seamless integration with data acquisition systems and signal analyzers equipped with IEPE constant current sources.
