PCB Piezotronics Inc., Vibration Div., Depew, NY, offers Series 495B10 differential remote charge converters for use with differential charge output piezoelectric accelerometers. Charge converters operate from 10–32 VDC over a –25°C to 85°C temperature range and are available in charge sensitivities of 2 mV/pC or 10 mV/pC. You can specify a low frequency roll off of 10, 15, 20, or 25 Hz. The devices convert a transducer's differential high-impedance charge input signal to a low-impedance voltage output and supplies the normal acceleration output along with a separate integrated velocity output.
