trueDGS^® Transducers

TrueDGS Angle Beam Ultrasonic Testing Transducers

New, patent-pending trueDGS technology from the GE's Inspection Technologies business has allowed the company to develop and introduce a range of ultrasonic trueDGS angle beam probes which:

Offer increased accuracy in sizing of flaws using the DGS method.
Provide the same accuracy as circular straight beam probes
Are available as single elements and phased array transducers (not yet available).
Ensure accurate, compliant ultrasonic inspection in a wide range of applications
Are accompanied by updated trueDGS software for the USM GO, USM 35 and Phasor Series flaw detectors. Click this link to Obtain Updated trueDGS software for your instrument.

Features & Benefits

The ultimate level of precision and repeatability for the DGS flaw sizing method
Revolutionary patent-pending design provides:
- Unrivalled accuracy in sizing small flaws using the DGS method
- Accuracy previously only available in circular straight beam transducers
- Savings on scrap costs due to significantly reduced chance of flaw over sizing
Compatibility with electronic DGS on the USM GO, USM 35 and Phasor Series flaw detectors
Legacy DGS probe familiarity with improved results driven by innovation
Improved ergonomically-designed die cast housing for durability
Replacement soles (sold separately) for extended service life
Side mount Lemo 00 connector

Applications

General inspection using the DGS method
Weld inspection
Tubes, pipes, pressure vessels, containers, pumps, valve housings
Turbine blades & shafts
Wheel rims
