Cygnus 1 EX Intrinsically Safe Ultrasonic Thickness Gauge

Conduct accurate corrosion surveys safely in explosion-risk areas without removing protective coatings. The Cygnus 1 EX is an Intrinsically Safe (IS) Ultrasonic Thickness Gauge, certified to ATEX, IECEx, and CSA standards for use in Zone 0 and Zone 1 hazardous areas. It uses the Multiple-Echo technique to measure metal thickness through coatings (up to 20 text{ mm} thick). This rugged, compact gauge ensures safe, accurate corrosion monitoring and integrity checks in environments like petrochemical and offshore facilities. Supplier: Cygnus Instruments Ltd.

Description

Detailed Overview

An intrinsically safe (IS) ultrasonic thickness gauge certified for use in hazardous, potentially explosive environments (Zone 0, 1, and 2). It utilizes the Multiple-Echo technique to take accurate through-coating thickness measurements. The solution provides safe and reliable corrosion assessment on assets in the oil, gas, and chemical industries without compromising safety regulations.


The ONLY intrinsically safe multiple-echo gauge, certified for use in Zone 0 and Zone 1 hazardous areas.

  • This gauge is engineered with triple-echo technology to accurately measure metal thickness through up to 20mm of coating without removing it, specifically certified for explosive atmospheres.
  • Its robust, sealed design provides maximum protection against impact and environmental ingress, ensuring safety compliance on petrochemical and offshore sites.
  • The core components are the intrinsically safe gauge body, a probe, a cable, an operating manual, and a rugged carry case.

Top Features & Benefits

  • Intrinsically Safe (IS) certified for use in hazardous (explosive) environments.
  • Multiple-Echo technology for accurate measurements through coatings.
  • Minimizes the risk of false readings.
  • Durable, shockproof, and water-resistant casing.
  • Large LCD display.

Primary Uses & Functions

A rugged, handheld, intrinsically safe gauge for reliable thickness measurements in Zone 0 Explosive Atmospheres (e.g., oil & gas, chemical plants) using the multiple-echo technique.


Real-World Applications

  • Thickness measurement in Zone 0 Explosive Atmospheres
  • Inspection in Chemical plants, Fuel depots, and Mines
  • Inspection of Oil and gas production facilities (pipelines, offshore platforms)
  • Inspection of Petroleum/chemical storage tanks and processing vessels
  • Thickness measurement on road transport tankers carrying explosive contents
