Hazardous‑area operators face relentless pressures: high temperatures, volatile conditions, tight compliance expectations—and corrosion that never waits. Maintaining asset integrity under these constraints is especially challenging when equipment must stay online. The Cygnus High Temperature Ex Probe is engineered precisely for this reality, enabling safe, accurate, in‑service inspection of hot assets.
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 cooling delays, and without compromising safety.
The probe is a trusted solution for:
- Oil and Gas Refineries
- Chemical Plants
- Nuclear Plants
- Petrochemical Refineries
- Processing Plants
In refineries, hot boilers, pressure vessels and pipelines face constant corrosive stress. Protective linings can degrade over time or suddenly, and early detection prevents unplanned outages and costly replacement. Chemical facilities rely on vast heat‑exchanger networks—hundreds of tubes and connections where undetected corrosion can jeopardise operations. Processing plants face similar challenges, where even water becomes corrosive under extreme heat inside process vessels.
Across all these environments, the need is the same: accurate, real‑time insights at temperature.
A Smarter, Faster, Safer Way to Inspect
The Cygnus High Temperature Ex Probe tackles the industry’s most persistent pain points:
- Unplanned downtime: Inspect at operating temperature—no cooling, shutdowns or isolation required. Continuous measurement accelerates inspection schedules and increases overall efficiency.
- Hot work restrictions: With the highest level of intrinsic safety, the system eliminates the need for Hot Work Permits, removing planning bottlenecks and reducing delays.
- Compliance pressure: Fully Ex‑certified for Zones 0, 1 and 2, with consistently high ultrasonic accuracy, it helps operators meet regulatory demands with confidence—especially where uncertified tools cannot be used.
- Protective coatings: Cygnus 1 Ex ultrasonic thickness gauge can measure substrate thickness through protective coatings of up to 20 mm thick, eliminating the time and cost of coating removal.
- Restricted access: Probes require access from only one side, enabling accurate wall thickness readings in constrained or hard‑to‑reach locations.
- Challenging environments: Designed for real‑world field conditions, including remote sites, extreme heat and harsh weather.
- Aging infrastructure: As assets extend beyond their original lifespan, routine corrosion monitoring becomes essential. Cygnus provides a fast, easy and reliable means of doing so.
- Environmental responsibility: Measuring through coatings reduces rework, waste and emissions—strengthening sustainability goals.
Every aspect of this tool is engineered with field reality in mind: fast deployment, intuitive handling, and repeatable accuracy even under extreme thermal conditions.
