Acoustic Emission Pre-Amplifier The AE-Amp amplifier is a universal pre-amplifier for acoustic emission sensors from various manufacturers. The AE-Amp can be used with passive, JFET, IEPE or constant voltage sensors. For applications where the sensor is also to be used as an actuator, the amplifier can be bypassed and an external signal can be output to the input. The AE-Amp is modular and can be expanded as a 19’’ system up to 48 channels per system. For smaller applications, the amplifier is available as a 2-channel version in a small box. In combination with the HVP500 high-voltage pulse generator and the AE-Amp-BU-xx base unit, regular pulse patterns can be output to the sensor. Each channel can be set independently. The setting options include gain (0 / 20 / 40 and 60 dB) and sensor supply via constant current (IEPE) or constant voltage. Control is via the USB interface.
