Cygnus Instruments Limited news

For over three decades, Cygnus has set the standard for underwater ultrasonic thickness measurement. The original Cygnus 1 Underwater gauge earned a reputation for rugged reliability and unmatched accuracy in the harshest conditions. Today, that legacy continues with the new Cygnus Underwater, engineered with advanced technology, modern usability, and the same uncompromising durability that professionals have trusted for years. As one diver’s story proves, true reliability doesn&rsq

Purpose built for seamless use with the Cygnus 1 Ex Ultrasonic Thickness Gauge, the probe is specifically designed for high temperature corrosion surveying in hazardous environments. Operating on assets up to 300°C, it gives technicians the ability to capture reliable thickness data at temperature - helping maintain integrity with confidence and make informed decisions without interrupting production. With Cygnus, high temperature inspection becomes possible without shutdowns, without coo

The Cygnus 1 Ex sets a new benchmark for ultrasonic thickness measurement in the oil and gas industry – where safety, uptime, and cost control are non-negotiable. Certified to IECEx, ATEX, and UKEX standards, it is the world’s only fully certified intrinsically safe ultrasonic thickness gauge (UTG) approved for ATEX Zone 0 – the highest safety classification – delivering unmatched reliability in ALL hazardous gas environments (Zone 0, 1, 2), coal mines and combustible

Though well-known as the tool for offshore inspection, it is also invaluable to inland waterway applications.

Offshore Applications

Cygnus Underwater is built for the harshest environments, and it doesn’t get much tougher than the most remote parts of the ocean. Offshore applications include:

• Offshore Platforms and Mobile Offshore Units (MOUs)
• UWILD and IWS class ship surveys
• Subsea pipelines
• Subsea storage tanks.

A Major Leap Forward in Underwater Thickness Measurement

The latest addition to the Cygnus diver range, the new Cygnus Underwater represents a significant advancement over its predecessor. Packed with innovative features, it is purpose-built to operate seamlessly in diverse conditions – ensuring greater measurement accuracy, enhanced usability, and robust performance in harsh subsea environments.

Why Cygnus Underwater Stands Out

Cygnus 1 Ex provides a first-class experience in user control and safety - unmatched within intrinsically safe Ultrasonic Thickness Measurement (UTM). Users can adjust the complexity of the settings to suit their level of experience - an invaluable tool allowing offshore teams in hazardous environments to carry out regular preventative structural monitoring without the costs of shutdown, disruption or outsourcing, whilst balancing increasing demand in a 24/7 production culture.

Several inspection methods have been used over time. The simplest is a visual inspection using a torch, checking for rust, damage, or residue. Whilst quick and easy, it’s limited by what the eye can see. This can be used in conjunction with chalk testing, where chalk powder is applied to the gasket, highlighting potential leaks wherever the chalk rubs away. Water hose testing involves spraying high-pressure water over the hatch cover. Although widely used, the hold must be empty to avoi

Explosive dust environments pose serious risks across many industries, often leading to catastrophic damage and tragic loss of life. When airborne dust particles accumulate in confined spaces and encounter an ignition source - such as electrical or thermal equipment - the result can be a powerful explosion caused by rapid pressure build-up. These environments often resemble dense fog due to low visibility, and unfortunately, they are more common than many realize. Historical data reveals that

The Cygnus Surface Range is built for inspecting possible corrosion onboard vessels, and to combat the challenges this presents. These lightweight, compact, hands-free gauges are shatter-proof and water-resistant (IP67) making them highly practical in a range of conditions. Plus, twin-crystal and right-angle probes increase flexibility for tight, awkward spaces.

Corrosion is a critical threat to the structural integrity of ships and offshore structures. These structures are constantly

To celebrate our best-performing product, 3 years since launch, we’re offering a FREE* Cygnus S2C-Ex Probe when you order a Cygnus 1 Ex PRO Anniversary kit (includes a Cygnus 1 Ex PRO Gauge and a Cygnus T5B-Ex Probe)!

Cygnus 1 Ex is Intrinsically Safe

When we say the Cygnus 1 Ex is Intrinsically Safe, we mean it’s designed to operate with extremely low energy levels - not enough to ignite a hazardous atmosphere, even in the event of a fault.
