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 in inspection services, uses Cygnus Gauges for pipelines, tanks, and vessel inspections. Our operators particularly love Cygnus for pipelines – as readings come quickly and accurately.

There are many within the industry who have been 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 the 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.
