Documents
The AIU is to be used with IEPE (Integrated Electronics Piezo-Electric) accelerometers and strain gauges. The unit provides a stabilised supply for excitation. The voltage output from the IEPE is attenuated and buffered by the AIU at fix gain of 0.4 to convert the 10V full scale measurement from an IEPE device to an output in the range of 0.5 to 4.5V
