An ultra-low noise, wide bandwidth, fixed-gain 40dB TOFD PreAmplifier, suitable for use with any ultrasonic transducers and system.
Overview

The PreAmplifier from Phoenix can be used for TOFD inspections when long probe leads are used and additional gain is required at the front-end. The PreAmplifier will enhance weak signals and improve the effective signal-to-noise of the system. Available as 40dB TOFD 1, 2 or 4 channel.

Features

  • 40dB Gain
  • Ultra low noise
  • Wide signal bandwidth
  • Output capable of driving long cable lengths
  • TOFD (twin crystal)
  • Low power – single 9V PP3 battery or external 5-12 VDC
  • Rugged and small enclosure
