Cygnus Instruments Ltd
The Safest Corrosion Gauge for ALL Hazardous Gas Zones
Gas Explosions and Hazardous Environments
High-risk environments include oil and gas refineries, chemical plants, storage tanks, fuel depots, road and sea tankers, and industrial facilities. Maintenance checks are vital to prevent leaks and accidents, but the equipment itself must be safe to use in explosive atmospheres.
Cygnus 1 Ex – Intrinsically Safe Design
The Cygnus 1 Ex ultrasonic thickness gauge is certified for safe use in areas with ignitable gases, vapours, or dust. Its intrinsic safety technology limits energy and heat, ensuring no sparks or arcs can ignite hazardous atmospheres—even under fault conditions. Key features include:
- Limited output energy
- Anti-static enclosure
- Redundant safety components
- No high surface temperatures under damage or fault.
Globally recognised under IECEx, ATEX, and North American standards, intrinsically safe equipment is suitable for all Zones and Divisions. Cygnus 1 Ex is the only gauge worldwide approved for ATEX Zone 0, equivalent to NEC Class I Division 1 Group ALL. It is also certified for Zone 1 (occasional risk) and Zone 2 (rare, short-term risk). Zones can change dynamically—for example, leaks can elevate an area from Zone 1 to Zone 0.
Advanced Features for Hazardous Inspections
Cygnus 1 Ex enables safe, efficient inspections without shutdowns or Hot Work permits. Customers praise it as “versatile, multifunctional, robust, and intuitive.” Benefits include:
- Three measuring modes with probes for materials and coatings up to 20mm
- Manual Measurement Mode for heavy corrosion, with adjustable gates and Time-Controlled Gain (TCG) to boost weak echoes
- Comprehensive data logging: linear, template, 2D/3D grids, 16 patterns, annotations, and Radial Points** for detailed analysis.
Conclusion
The Cygnus 1 Ex represents a major step forward in safe inspection technology, combining world-class certification with advanced functionality to protect lives and assets in the most hazardous environments.
