trueDGS® 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.
