Endevco’s Model 2771C-XX ultra-low-noise remote charge converter is used with charge output piezoelectric sensors within mechanical system health monitoring, nuclear power plant/regenerative energy, and environmental testing applications. The device offers a rugged two-wire, single-ended design that operates from constant current power (4-20 mA). Both signal output and current to the RCC are carried along the same wire. Housed in a rugged, small package, the charge converter offers broadband noise range down to 5 µVrms, with a frequency response of 0.4 to 50 kHz. Units can withstand shock loads of up to 100 g peak and are radiation tested to 1.0 Mrad. They come in three different fixed gains of 0.1 mV/pC, 1.0 mV/pc, and 10 mV/pC and can support Transducer Electronic Data Sheet technology for smart sensor and larger channel count applications.
