The TRPP 5810 unit is a high-performance remote pulser/preamplifier dedicated to TOFD inspection and compatible with the Olympus NDT scanner line as well as PV-100 and PV-200 weld inspection systems.
This remote pulser/preamplifier provides an optimum signal-to-noise ratio for TOFD inspection by combining a 40 dB preamplifier with a remote high-voltage (200 V) pulse repeater in a single, small enclosure. The TRPP 5810
supports two UT channels, enabling simultaneous inspection with one or two pairs of TOFD probes.
Application
|
|
The TRPP 5810 can be used as a pulser and/or preamplifier.
TRPP 5810 as a Pulser
- Provides an additional pulse gain in order to generate a stronger signal when needed to reveal difficult-to-detect flaws.
TRPP 5810 as a Preamplifier
- Provides the additional gain or broadband signal-to-noise enhancement necessary for optimum signal acquisition on thick sections of material exhibiting high ultrasonic attenuation.
- Allow driving of long cables from remotely located sensors.
Pulser
- Remote, high-voltage (200 V) pulse repeater
- PRF of up to 10 kHz at 100 ns per channel and up to 20 kHz at 50 ns for a single channel
- Outputs are protected against misuse and bad connection to pulser outputs.
Preamplifier (Receiver)
- 40 dB preamplifier
- Accommodates probe frequency range from 1 MHz to 15 MHz.
- Inputs and outputs are protected against misuse and bad connection to pulser outputs.
