Low-noise remote charge converter 2777A series

Model 2777A-XX-YY Differential Remote Charge Convertor (DRCC) is a low noise ruggedized device designed for use with differential piezoelectric transducers. This device converts the transducer’s high impedance charge input to a low impedance voltage output. The acceleration output is also integrated to produce an AC voltage proportional to velocity output. The low impedance output from the DRCC provides less susceptibility to noise in the cabling from the DRCC to the main signal conditioning instrument, and it also makes the system’s noise level insensitive to the capacitance of the cable connecting the DRCC to the main conditioner. This is a low noise device with a frequency response of 10 Hz to 10 kHz. The DRCC operates over the temperature range of 5°F to 185°F (-15°C to 85°C).
