IEPE 8 Channel Power Supply and Signal Conditioner



Datasheet available upon request.

The ASC-1408-PXI 8 Channel IEPE Preamplifier transforms the output of piezo-ceramics or other Constant Current Power (CCP) devices into a low impedance voltage signal that can be transmitted into a measurement device. Each channel of the 8 Channel IEPE Preamplifier provides a constant 4 mA current source to the sensor. The sensor then sends a vibration signal back to the supply where the sensor bias voltage is removed. The vibration signal with the DC bias removed is sent through an amplifier with a gain of 1 or a gain of 10, then to the output connector to the data acquisition system. 

Custom options are available with gain, 50 Ω line driving, and low / high pass filtering (all filtering options specified at 0.1 dB). A-Weighted filtering is also available. Please contact IC2 to discuss your custom requirements.
