PCB’s New Remote Charge Converters Complement Differential Sensors

April 18, 2006—The Vibration Division of PCB Piezotronics introduced the Series 495B10 differential remote charge converters for use with differential charge output piezoelectric accelometers.

Differential sensors and sigal conditioning electroics are used in flight test applications due to their common mode noise rejection, which reduces noise in the measurement signal. These rugged, low-noise units convert a transducer’s differential high impedance charge input signal to a low impedance voltage output and supplies the normal acceleration output as well as a separate integrated output for velocity.

The converters operate from 10-32 VDC power over a temperature range of -13 degrees F to 185 degrees F 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" threaded connector and the output is a six-pin bayonet-style connector.
