AE–Preamplifier Data Sheet

Product catalog summary

Overview: The AEP5 and AEP5H are general-purpose wide-band preamplifiers designed for single-ended AE sensors. The primary distinction between the two models is their frequency bandwidths. Gain settings of 34 dB or 40 dB can be selected via an internal switch, requiring the housing to be opened to prevent accidental changes.

Technical Specifications:

Gain: 34 dB or 40 dB (switch selectable)
Bandwidth: AEP5: 2.5 to 2400 kHz; AEP5H: 20 to 2400 kHz
Input Impedance: 50 MΩ | 22 pF
Power Supply: 28 VDC via signal cable
Power Consumption: 1.8 W
Input Range: 100 mVPeak @ 34 dB, 50 mVPeak @ 40 dB
Output Range: 10 VPP into 50 Ω
Max Pulse Through: 450 VPP

Noise Levels: Noise is measured in dBAE and µVRMS across different filters and input conditions.

Mechanical and Environmental Specifications:

Connectors: BNC for both input and output
Case Material: Aluminium
Operating Temperature: -20 to +85 °C
Vibration: Sinus sweep 2 Oct/Min, 5 to 50 Hz, 20 g
IP Rating: IP 40
Dimensions: 30 x 55 x 90 mm
Weight: 160 g

Standards and Directives: Complies with EMC Directive 2014/30/EU and various EMC and AE standards.

Accessories: Includes mounting holders and BNC cables. Filters are to be used in subsequent measurement chains.

Handling and Maintenance: Proper handling is crucial to avoid damage. Regular checks are recommended to ensure functionality, especially after exposure to severe conditions.

Catalog excerpts

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.
