Acoustic Emission Preamplifier
compact · robust · wide-band · low-noise · pulse through

 

AEP4:

  • 34 dB or 40dB (jumper-selectable) into 50 Ohm
  • 2,5 kHz to 3.8 MHz, (to 1MHz full power 10VPP into 50 Ohm)
  • +28VDC24mA (no signal) 64mA (10VPP into 50 Ohm)
  • Noise: 10µVPK,1.2µVRMS @90-850kHz
  • Pulse-through calibration bypass for automated sensor coupling test
  • 65 * 60 * 35 mm (BNC connector not considered) 200g
  • 5°C to 105°C

 

AEP4-IS: like AEP4, but
  • Sensitivity increase: AEP4-IS delivers up to 11dB higher signal amplitude than preamplifiers and 1.2m sensor cable, due to the short internal cable.
  • internal electronics protected by epoxy molding
  • 3 strong magnets
  • for sensor cases -M and -H

AEP4H-ISTB:
  • optimized for tank floor testing
  • designed for sensor VS30-V
  • 46dB into 50Ohm
  • Bandwidth (-3dB): 20kHz to 1MHz
  • Noise (VS30-V connected): 18dBAE(<10µVPK) @ 20-45kHz
  • internal electronics protected by epoxy molding
  • Power supply: 28VDC24mA (no signal) 64mA (10VPP into 50 Ohm)
  • Pulse-through calibration bypass for automated sensor coupling test
  • Dimensions: H: 60mm (2.36 in.), (incl. magnets), W: 57mm (2.24 in.)
    L: 65mm (2.56 in.) (+18mm/0.7 in. BNC),
  • Weight: 370gr
