Universal Amplifier for Acoustic Emission Analysis

Preamplifier for Acoustic Emission Sensors from various Manufacturers The AE-Amp amplifier is a universal preamplifier for acoustic emission (Acoustic Emission) sensors from various manufacturers. The AE amp can be used with passive, JFET, ICP / IEPE or constant voltage sensors.

The AE-Amp has two independent channels and is available in either a boxed version or a rack-mountable module. Each channel has 4 gain levels: 0 dB, 20 dB, 40 dB and 60 dB. These can be set mechanically on the front or via the USB / RS485 interface.

The input stage is AC coupled at a lower filter cutoff frequency of 25 kHz. Thus, signal components in the audible range are largely filtered out. The upper bandwidth is between 1 and 3 MHz depending on the amplification level.

If the connected sensor is also used as an actuator, it is possible to switch off the amplification stage via software and to connect an additionally connected high-voltage pulser to the sensor input.

• 2 independent channels per module
• Switchable amplifier stages: 0 dB, 20 dB, 40 dB and 60 dB per channel
• 1 MHz bandwidth at gain 60 dB
• Low noise
• High voltage pulser input (500 V)
• USB / RS485 software interface for the configuration of all settings
