November 2, 2009
The Model 2771C-XX from Endevco Corp., San Juan Capistrano, CA, is an ultra-low-noise remote charge converter (RCC) for use with charge output piezoelectric sensors within mechanical system health monitoring, nuclear power plant/regenerative energy, and environmental testing applications. The device offers a rugged, 2-wire (IEPE), single-ended design that operates from 4–20 mA constant current power. Both RCC signal output and current to the RCC are carried along the same wire. Features include broadband noise down to 5 µVrms; 0.4 to 50 kHz frequency response; fixed gains of 0.1 mV/pC, 1.0 mV/pC, and 10 mV/pC; support for TEDS; and the ability to withstand shock loads up to 100 g peak and radiation to 1.0 Mrads.
