Safe NDT in explosive atmospheres

26 November 2021

Usually, the Cygnus 1 Intrinsically Safe Ultrasonic Thickness Gauge is the only choice for use in Zone 0 and Zone 1 hazardous areas. However, many locations surrounding these areas can be classified as Class 1 Division 1 and therefore don’t necessarily require the use of intrinsically safe equipment to operate there, instead these areas can use Explosion Proof (XP) equipment.

The Cygnus 6+ Pro is Explosion-Proof (XP) and offers safe operation in some explosive atmospheres: Class 1, Division 2, Group D locations only, as defined in NFPA 70, Article 500. Such locations are common in industries where hazardous zones only cover a proportion of vast production sites, including chemical plants, fuel depots, processing plants, oil and gas production facilities and mines.

This is where the 6+ comes in, offering more measurement options and benefits to a broader set of corrosion inspection applications, safely.

A closer look at the Cygnus 6+ Pro

The highly intuitive Cygnus 6+ PRO ultrasonic thickness gauge boasts an array of useful features for professional users, including three versatile measuring modes, A-scan, B-scan, and Measurement Stability Indicator (MSI^TM) to give reliable measurements. The A-scan display allows you to check the back-wall echo signal whilst the Gain or A-scan range can be manually adjusted where necessary. And the comprehensive data-logging feature records your measurements for hassle-free reporting and analysis afterwards.

What’s more, the 6+ comes with a Temperature Compensation feature, so when used with Cygnus High Temperature probe, it can measure the remaining wall thickness of high-temperature (up to 300^oC), in-service assets without shutdown or isolation.
