Low-Noise Remote Charge Converter

Endevco Corp. launched Model 2771C-XX, an ultra-low-noise remote charge converter (RCC) designed for use with charge output piezoelectric sensors within applications such as nuclear power plant/regenerative energy and environmental testing. The model offers a rugged two-wire (IEPE), single-ended design that operates from constant current power (4-20 mA). Both RCC signal output and current to the RCC are carried along the same wire. Housed in a small package, the charge converter offers broadband noise range down to 5µ V rms, with a frequency response of 0.4 to 50 kHz. Units are designed to withstand shock loads of up to 100-g peak and are radiation tested to 1.0 Mrads. The model is available with three different fixed gains: 0.1 mV/pC, 1.0 mV/pC, and 10 mV/pC. It can also support TEDS (per IEEE P1451.4) for smart sensor and larger channel count applications and includes an available M1 Version with male BNC, to facilitate easy panel mounting.
