We often describe the Cygnus 1 Ex Ultrasonic Thickness Gauge as “Intrinsically Safe, certified to Zone 0, suitable for hazardous areas.” But what do these technical claims mean? In this campaign, we aim to unpack the terminology and explain the regulations behind equipment used in explosive or hazardous environments.
To celebrate our best-performing product, 3 years since launch, we’re offering a FREE* Cygnus S2C-Ex Probe when you order a Cygnus 1 Ex PRO Anniversary kit (includes a Cygnus 1 Ex PRO Gauge and a Cygnus T5B-Ex Probe)!
Cygnus 1 Ex is Intrinsically Safe
When we say the Cygnus 1 Ex is Intrinsically Safe, we mean it’s designed to operate with extremely low energy levels - not enough to ignite a hazardous atmosphere, even in the event of a fault.
Intrinsic safety is a protection concept used in hazardous area environments. It ensures that:
- Power levels are kept low
- Stored energy is minimized
- Sparks and heat capable of igniting gases or vapours are prevented under any conditions.
This makes it possible for intrinsically safe equipment to be certified for:
- Zone 0 (where explosive gases are present continuously or for long periods)
- Zone 1 (likely to be present during normal operations)
- Zone 2 (unlikely to be present in normal operations).
In contrast, other safety... Read more about what we really mean when we say the Cygnus 1 Ex is intrinsically safe.
