Cygnus DIVE underwater ultrasonic thickness gauge

Russell Fraser Sales introduces the next generation of its popular wrist-mounted Cygnus DIVE underwater thickness gauges.

The new Cygnus DIVE underwater ultrasonic thickness gauge features a twin-crystal probe option to assist with measurements on uncoated materials such as anchor chain links, extremely corroded steel and plastic outfall and dredge pipes. Also exclusive to Cygnus thickness gauges, the new Measurement Stability Indicator (MSI) in the DIVE gauge indicates when a reading in single-echo mode is stable by turning the thickness reading from red to yellow.

Given the poor visibility conditions during underwater inspections, the new DIVE has been designed with a super bright AMOLED display, which is easily viewable to the diver and his camera. Updated topside and reporting software now allows measurements and A-Scans to be displayed on the surface and data logged topside.

The Cygnus Multiple-Echo technique has been recommended and endorsed by the world’s leading classification societies (DNV, Lloyds and others) for measuring the remaining metal thickness through protective coatings. Though the Multiple-Echo technique provides accurate and reliable measurements, this measuring technique can sometimes be difficult to achieve when measuring on extreme front face and back wall corrosion and round bars such as anchor chain links.

Cygnus has therefore introduced the Single-Echo technique using twin-crystal probes into their product range, providing users with the flexibility to alternate between the two measurement methods.
