Specifically designed for underwater remotely operated vehicles, Cygnus offers a dedicated ROV Mountable thickness gauge, depth rated to 2,000 m (6,526 ft). This mountable measurement gauge again, benefits from the multiple-echo technology found in all our ultrasonic measuring devices. It is truly versatile and designed to measure metal thickness through coatings in the harshest operating conditions.
Dedicated software reveals the date, time and thickness readings on the surface which may be logged or stored. In addition, a Topside Repeater (TSR) is available providing the ability to present the thickness measurements remotely and overlay them on to a video signal. This permits the measurements to be superimposed on the ROV camera’s monitor screen.
Cygnus Instruments builds all of its equipment in the UK using only genuine and original parts and components – including Lemo® Connectors and Peli® Cases.

For optimum performance of the ultrasonic thickness gauge it is essential to utilise the appropriate probe for the specific material being tested. Here below are the probe options available.
|Single crystal soft-faced compression||13 mm – 2.25, 3.5 or 5 MHz|
The Cygnus Topside Repeater (TSR) is available as an option and has the facility to display the thickness measurements remotely and overlay them on to a video signal. This allows the measurements to be superimposed on the ROV camera’s monitor screen.
Cygnus G1 Observation, Inspection, Light Work Class ROV Probe Handler
The Cygnus G1 Probe Handler is designed for use on Observation, Inspection and Light-work class ROVs. Constructed from acetal it is both strong and lightweight it features an adjustable mounting bracket allowing optimum positioning of the UT probe. The UT probe is located in an articulated mount that allows up to 15 degrees of movement in both planes allowing automatic alignment of the probe face to the measurement surface making the ROV pilot’s job easier.
