Multiple-Echo Through Coating Thickness Gauges from Cygnus

Using the Multiple-Echo technique approved by Classification Societies, all Cygnus ultrasonic thickness gauges provide accurate and reliable metal thickness measurements without the need to remove coatings. The PLUS models also incorporate Single-Echo and Echo-Echo measuring modes for testing heavily corroded metals with front and/or back wall corrosion and pitting.

The wrist mountable Cygnus 4+ thickness gauge is well suited for marine surveys, with its simple to use menus on a large colour LCD screen; data logging with auto-log function; and radial points capability. For further validation of measurements, this UTM gauge also offers live A-scan and MSI™ (Measurement Stability Indicator) – ensuring only stable readings are displayed.

Testimonial from Dale Bradley – Principle Marine Surveyor

"Having owned and operated the Cygnus models two and three I recently upgraded to the Cygnus 4+. Cygnus has always been a brand to associate with reliable and accurate UTM readings. And working for a number of high-profile clients and MCA classification societies, this accuracy is mandatory. The Cygnus 4+ is not only small and lightweight, it is also wrist mounted to keep your hands free."

Dale continues "the added functions are endless, and you can add comments in for single readings and add additional readings (outside the pre-determined grid) in as you are conducting the survey. This is very useful if defect areas are identified as they can be clearly documented on the spot, rather than having to return after the record is completed. The back-office software is user friendly and has plenty of fields of extra information that can be added apparent to the vessel. After having a demonstration of the 4+ at the 2019 Seawork’s show I ordered the unit the following day. The staff are very helpful and knowledgeable, and the unit arrived promptly. The 4+ has helped me become more time efficient and produces a very informative report that is well accepted within industry".

Pioneers of the multiple-echo measuring technique which has long since been an industry standard for through coating measurement of material thickness, Cygnus thrive on developing a product range that is application-driven and user-focused.

Designed for the Engineer who needs to take quick and accurate thickness measurements, the MK5 Cygnus 4+ is a highly reliable, extremely rugged and simple to use ultrasonic thickness gauge.

The unit is perfect for testing levels of wear and corrosion on industrial machinery, factory infrastructure, boiler tubes and pressure vessels. This gauge has been rigorously tested to military specification: drops from height onto concrete, extreme vibrations and extreme temperatures – and is completely environmentally sealed to IPX7 and IP6X.

While the Cygnus 4+ has been specifically designed to be easy to operate, it also has an excellent array of features including: versatile measuring modes (multiple-echo, single-echo and echo-echo); an A-scan display that helps to verify true back wall readings in difficult measuring applications; data logging that stores up to 500,000 readings with their A-scans; and MSI™ (Measurement Stability Indicator) which verifies stable and reliable readings.

The gauge has a large colour LCD display that can be viewed in all lighting conditions, an easy to use keypad and an intuitive menu. The gauge body has been designed to be comfortable to hold and protects against bumps whilst offering maximum strength with its hard-internal shell.

Cygnus’ most advanced gauge in the MK5 range is the Cygnus 6+ PRO. Developed with a primary focus on the non-destructive testing industry, the Cygnus 6+ provides the same features as the Cygnus 4+ as well as comprehensive data logging, B-scan, Bluetooth™ and a dual display.

Also available is Cygnus 1, the world’s only ultrasonic thickness gauge that has been certified intrinsically safe to the highest possible ATEX rating: Group I & Group II / CSA Class 1 Group A, B, C & D Division 1; this means that the Cygnus 1 Intrinsically Safe thickness gauge can be used in Zone 0, Zone 1 hazardous areas – and requires no plant shutdown or hot work permit. This makes it the number 1 choice for all engineers working within potentially explosive environments such as food processing plants.
