Crowcon’s Xgard IR infrared (IR) gas detector is now approved to the latest amendment of the Marine Equipment Directive (MED, 96/98/EC). This means the low cost detector can be used to detect flammable gases and vapour hazards on tankers, drilling ships, FPSOs, dive vessels, coastguard vessels, ferries and other marine vessels.
Applications for the Xgard IR include pump rooms and monitoring leaks in storage tanks, pipes and valves. It provides fast early warning of gas accumulations before concentrations reach flammable levels. Detection is in the range 0 – 100% LEL.
Unlike conventional sensors (such as catalytic pellistors) the Xgard IR’s sensor is immune to being poisoned or inhibited by other substances. Infrared sensing has other benefits too: unlike pellistors, IR sensors will fail to safety, detect flammable gas in inert backgrounds and are not damaged by high gas concentrations.
The Xgard IR is available with a 316 stainless steel enclosure for maximum corrosion resistance in the most extreme marine environments. The sensor, which has a life expectancy of over 5 years, is a simple plug-in module that makes replacement quick and easy. ATEX, IECEx and UL approved for use in hazardous areas, the Xgard IR is also Exd flameproof rated.
The standard junction box is designed for both wall and ceiling mounting, and four cable gland options ensure compatibility on any site. The detector takes a range of accessories for harsh or wet conditions and for remote sampling.
