Crowcon Xgard IR LPG Infrared Gas Detector

The Xgard IR LPG from Crowcon is a new, low-cost infrared (IR) fixed gas detector designed to detect liquid petroleum gas (LPG) hazards before concentrations reach flammable levels. 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 sensors. The detection range is 0-100% lower explosive limit. Infrared sensing has additional benefits over traditional sensing. Unlike catalytic pellistors, IR sensors detect flammable gas in inert backgrounds, are not damaged by high gas concentrations. The Xgard IR consumes half the power of comparable catalytic bead detectors. The new IR LPG sensor can be specified with two types of enclosures: polyester-coated aluminum or 316 stainless steel for maximum corrosion resistance in extreme environments. 800.5-CROWCON, www.crowcon.com
