New differential remote charge converters for aerospace applications

The Vibration Division of PCB Piezotronics, Inc., introduces Series 495B10 differential remote charge converters, for use with differential charge output piezoelectric accelerometers. Differential sensors and signal conditioning electronics are widely used in flight test applications due to their common mode noise rejection, which greatly reduces noise in the measurement signal. These rugged, low noise units not only convert a transducer's differential high impedance charge input signal to a low impedance voltage output and supplies the normal acceleration output, but also supplies a separate integrated output for velocity.

Series 495B10 charge converters operate from 10 to 32 VDC power, over a temperature range of -13 F to +185 F (-25 C to +85 C) and are packaged in a lightweight aluminum housing. They are available in charge sensitivities of either 2 mV/pC or 10 mV/pC. In addition, the user can specify a low frequency roll off of 10, 15, 20 or 25 Hz. The input is a two-pin, 7/16 inch threaded connector and the output is a six-pin bayonet-style connector.
