MODEL
2792B
ISOTRON ® Signal Conditioner
Model 2792B
• 9-Channel Constant Current Supply/
Amplifier for ISOTRON (Piezoelectric
Voltage Mode) Accelerometers
or Remote Charge Convertors
• Transducer Sensitivity Normalization
and LED Status Indicators
• Wide Frequency Range: 1 Hz to 80 kHz
DESCRIPTION
The ENDEVCO ® Model 2792B nine-channel signal conditioner is a versatile power supply/amplifier
for ISOTRON accelerometers and other piezoelectric voltage mode transducers. It can also power
Remote Charge Convertors (RCC) in a high impedance piezoelectric measurement system. Each
channel provides a constant current excitation (4 mA or 10 mA) for the transducer or the RCC, input
sensitivity normalization, and a switched gain output. Individual LED status indicator informs the user
of short, open, or normal conditions.
