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