Ultrasonic Thickness Gauge for Potentially Explosive Environments

Cygnus Instruments has been designing and manufacturing high quality ultrasonic inspection equipment in the UK for over 35 years. During that time, Cygnus has built an enviable relationship with customers not only for the physical quality of the instruments it makes, but also for making the most reliable and accurate products too.

At the heart of Cygnus Instruments’ reputation for reliability and accuracy lies the Cygnus-pioneered “multiple echo technique”. By using three distinct return pulses of ultrasound, Cygnus thickness gauges will remove almost all possibility of error – and simultaneously read through coatings. Cygnus multiple echo gauges are also extremely simple to calibrate and use.

As one satisfied customer recently noted:

“TechCorr, a global leader of inspection services, uses Cygnus Gauges for pipelines, tanks and vessel inspections. Our operators particularly love Cygnus for pipelines – as readings come quick and accurate.

There are many within the industry who are using Cygnus thickness meters for more than 20 years… I myself have used Cygnus’ Intrinsically Safe UT meter from the early stages of my career – and that goes back to more than 25 years for sure”.

The Cygnus 1 Intrinsically Safe thickness gauge is certified intrinsically safe to ATEX Marking Group I & Group II; CSA Class 1 Group A, B, C & D Division 1; IECEx Ex ia IIC T2/T3/T6 Ga, Ex ia I Ma. This means that the unit is ideal for use in Zone 0 and Zone 1 hazardous areas – and requires no plant shutdown or hot work permit. In addition to oil & gas production facilities, the gauge has been approved for use in mines and is also useful in maintenance and inspections of LPG vessels and FPSOs.

The gauge body has been designed to be rugged, durable and shock-proof, and has been IPX5 rated, meaning that this heavy-duty sealed unit is highly dirt and dust resistant.

In addition to this Intrinsically Safe unit, Cygnus offers a full range of thickness gauges for any and all applications. Call us on +44 (0)1305 265533 and let us help you with your application.
