Low-noise remote charge converter 2771CM2-1

The model 2771CM2 remote charge converter, is designed to operate with high temperature piezoelectric transducers that have low impedance when exposed to very high temperatures (1200°F, 650°C). The device converts the transducers charge output to a proportional voltage. This unit is a two-wire device with the output signal available on the same two wires that carry the supply current from the constant current power supply. The 2771CM2 supports IEEE P1451.4 (A Smart Transducer Interface for Sensors and Actuators) and contains an identification code via TEDS (Transducer Electronics Data Sheet). The charge transducer identification, actual unit gain and calibration data are stored in the TEDS (256-bit Non-volatile memory). This unit features a fixed gain of 1.0 mV/pC, low noise and operational over a constant current range of 4 to 20 mA and a temperature range of -40°C to +125°C.
