AE–Preamplifier Data Sheet AEP5 / AEP5H AEP5 / AEP5H are general purpose wide-band preamplifiers supporting single ended AE sensors. The only difference between AEP5 and AEP5-H are different frequency bandwidths. Gain can be set to 34 dB or 40 dB by a switch located inside the preamplifier. Changing the gain requires opening of the housing as described in the specification of preamplifiers. Thereby accidental change of gain is excluded. As every preamplifier of Vallen Systeme GmbH the AEP5 / AEP5-H can put a voltage pulse (up to 450 VPP) through the preamplifier to the connected AE-sensor (sensor coupling test) while the supply voltage for the preamplifier is interrupted. Technical Specification (typical) Preamplifier Gain @ 50 Ω [dB] Input Range [mVPeak] Output Range into 50 Ω [VPP] 450 (suited for AMSY series) Noise (max. 1/s for dBAE values) Filter 95 to 300 kHz [dBAE] | [µVRMS] Filter 95 to 850 kHz [dBAE] | [µVRMS] Mechanical and Environmental Specification Input Connectors Case Material Output Connector Vibration – Sinus sweep
