New Infrared Gas Detector For LPG Gas Hazards
The Xgard IR LPG from Crowcon is a new, low cost infrared (IR) fixed gas detector designed to detect LPG* gas hazards before concentrations reach flammable levels. Typical environments requiring LPG monitoring include petroleum refineries, manufacturing processes, vehicle filling stations and buildings that use LPG as their main gas supply.
Conventional LPG detectors based on catalytic pellistors are susceptible to poisoning in some industrial atmospheres. This can make their readings unreliable and even destroy the sensor altogether. The new Xgard IR LPG is totally immune to poisoning and will reliably warn of LPG gas hazards in environments that are unsuitable for other types of sensor. The detection range is 0-100% LEL**. Infrared sensing has other benefits too. Unlike catalytic pellistors, IR sensors will fail to safety, detect flammable gas in inert backgrounds and are not damaged by high gas concentrations.
The new IR LPG sensor can be specified with two types of enclosure: polyester-coated aluminium or 316 stainless steel for maximum corrosion resistance in extreme 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*** and IECEx**** approved for use in hazardous areas, the Xgard IR LPG is 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.
