IEPE 8-Channel PXI


The ASC-1408-PXI 8-Channel Integrated Electronics Piezo-Electric (IEPE) Power Supply provides a constant current source that can be used by piezo-electric sensors, or other Constant Current Power (CCP) devices / sensors.

The device features a selection of 1x or 10x gain and 4 mA excitation current in a convenient PXI card package. This portable, rechargeable battery powered device’s flat frequency response provides true, source-accurate broadband data. Versatile and reliable – the ASC-1408-PXI is well-suited for precision measurement applications.

Each channel of the 8 Channel IEPE Preamplifier provides a constant 4 mA current source to the sensor. The sensor then sends a AC signal back to the supply where the sensor bias voltage is removed. The AC 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.
