Metallic and Non-Metallic Tubes (DCUT)

No items found.

POWERUT TG-IL uses Dry-Coupled UT (DCUT) sensors to measure thickness of metallic and non-metallic materials with optimum lateral resolution and accuracy.


  • Proprietary DCUT sensors with no-couplant.
  • Ambient temperature inspection.
  • Wheel and touch probe sensors for continuous and spot measurements.
  • Great accuracy (+/-2.5µm) and lateral resolution (1mm).
  • Thickness readings (lateral resolution) of 1mm at 2m/s.
  • Automatic calculation of eccentricity and ovality.
  • Thickness measurement on internally tapered tubes.
  • Applicable to finishing lines on tubes (stainless, carbon), pilger mills and many other applications.


  • Technique:
    – Dry-coupled, High-power Piezoelectric Transducer
  • Materials Inspected:
    – Metallic and non-metallic materials including most plastics and composites.
