Utility Crawler Add-Ons

Cygnus’s industry-leading ultrasonic thickness gauge can be integrated onto your magnetic crawler, allowing you to evaluate the thickness of steel on tanks, hulls or other metal surfaces without needing dive intervention or draining the asset.


Non-destructive Testing Tool, the Ultrasonic Thickness Gauge Probe


  • 0.1 MM Accuracy
  • Readings in Seconds
  • Modular Add-on
  • Reads through 12 MM of Marine Growth

This ultrasonic thickness (UT) probe presses on the surface, taking an accurate measurement even through marine growth or coatings. The data is then displayed and recorded via Cygnus software on a laptop.

The probe is able to take readings through up to 1/2″ or 12 MM of soft marine growth or coatings to take a reading of the steel. This is a great tool for corrosion surveys for UWILDs on FPSOs or Vessels, as well as for steel tanks and pipes and other surfaces.
