Since 1983, Cygnus Instruments (Stand 1) has been the leading manufacturer of Digital Ultrasonic Thickness Gauges (UTG) for reliable corrosion inspection and asset integrity management. Our most advanced, unique gauge is undoubtedly the Cygnus 1 Ex—the world’s only Zone-0 thickness gauge. This Ex gauge is not just safe but certified intrinsically-safe for all Hazardous Zones 0, 1, and 2.

With customer reviews favourably as “versatile, multifunctional, robust and intuitive,” this Ex-certified UTM gauge boasts 3 measuring modes for accurate thickness measurement on heavily corroded or coated metals. It ignores protective coatings up to 20mm thick and saves considerable time and money from removing coatings!

The Cygnus 1 Ex ultrasonic thickness gauge is the only one of its kind in the world certified to ATEX, IECEx, UKEX for Zone 0 - offering an invaluable leap forward for safe structural inspection of:

-  Oil and Gas refineries
-  Chemical Plants
-  Hazardous Storage Tanks
-  Fuel Depots
-  Road Tankers
-  Chemical, Oil and Gas Tankers
-  Industrial processing facilities in explosive atmospheres

This intrinsically-safe gauge provides first-class user control and flexibility and eliminates the need for plant shutdown or a Hot Work permit. Equipped with 3 measuring modes and a selection of probes, the gauge is capable of measuring a range of materials and metals with thick coatings or severe corrosion.

The great news for advanced users is the Manual Measurement Mode allows manual adjustment of gain and gates to suit your specific application. Like a flaw detector, its two gates can be positioned anywhere on the A-scan. You can alter the gate height, start-point and width. It also allows you to choose to measure from the first gate or between gates. Furthermore, if the 2^nd or 3^rd echo is weak, the Time-Controlled Gain (TCG) enables you to introduce different gains to boost the weaker echo(es), keeping the first echo the same. Such versatility makes measurements on tricky areas easier and more accurate.

When storing your data, you’ll enjoy equal flexibility. Comprehensive data logging offers linear, templates, and 2-D or 3-D grid formats, with 16 grid patterns and annotation capability. Radial Points enable further investigation on an area of interest or heavy corrosion, allowing you to add up to 12 additional measurements ‘around’ the principal measurement.

No matter how complex your inspection process is, the gauge is designed for seamless data analysis and report generation using Cyglink, easily connected via Bluetooth^TM or a data port. It can export data to Excel or generate PDF reports. The CygLink software allows you to transfer, manage and view data logger records, A-scans and B-scans, as well as templates, measurement comments, and material velocity tables.
