Cygnus 1 Ex: Safe, Reliable Ultrasonic Thickness Measurement
The Cygnus 1 Ex delivers unmatched safety and user control in intrinsically safe Ultrasonic Thickness Measurement (UTM). Its adjustable settings suit both novice and experienced operators, enabling offshore teams to monitor structural integrity in hazardous environments without costly shutdowns or outsourcing—vital in today’s 24/7 production culture.
Corrosion Monitoring on Vessels and Scrubbers
Corrosion in SOx scrubbers, intensified by hot exhaust gases and acidic wash water, can lead to catastrophic failures such as water ingress into engine rooms. Classification societies like DNV-GL mandate annual wall thickness checks, and Cygnus—trusted worldwide for over 40 years—provides reliable, easy-to-use ultrasonic testing equipment.
Certified Intrinsic Safety
Cygnus 1 Ex is the only ultrasonic thickness gauge certified Intrinsically Safe to ATEX, IECEx, and UKEX for use in hazardous gas Zones (0, 1, 2), coal mines, and dust Zones (21, 22). This ensures safe operation even on vessels carrying flammable cargoes.
Multiple-Echo Technology
The device employs Cygnus’ pioneering Multiple-Echo technique, reading through protective coatings without removal. This saves time and preserves expensive epoxy layers that guard against corrosion.
Efficiency Offshore
Designed for minimal disruption, the Cygnus 1 Ex features a Measurement Stability Indicator (MSI) for reliable readings, ergonomic design, and intuitive controls. Four quick function keys, dynamic screen views, and user access protection enhance usability. Two rechargeable batteries provide 8 hours of continuous use, while light/dark display modes adapt to any environment. Measurement, A-Scan, Data-logging, and B-Scan screens are easily rotated, and seamless reporting is enabled via Cyglink software with Bluetooth or data port connectivity.
