 The Endevco Model 2771A-XX Remote Charge Convertor (RCC)
is a low noise, two-wire, single-ended device designed
for use with piezoelectric transducers. This device transforms
the transducer's high impedance charge output to a low
impedance voltage proportional to the transducer's charge.
The signal output from the RCC is less susceptible to
noise pick-up because of its low impedance voltage. Also,
the shunt capacitance of the cable connecting the RCC
to the main conditioner does not significantly affect
the noise and sensitivity of the system.
The signal output from the RCC and the current to the
RCC are carried with the same wire. The 2771A has fixed
gains of 0.1 mV/pC, 1.0 mV/pC, 10 mV/pC or 20 mV/pC. This
is a low noise device, with a frequency response of 1
to 40 kHz. It operates within a constant current range
of 4 to 20 mA.
Features:
• Rugged small package
• Two-wire system
• Low noise
• Wide frequency response
• Four different gains
