New Infrared Flammable & CO2 Gas Sensor Detects Hazards Where Conventional Sensors Fail
The Xgard IR from Crowcon is a new, low cost infrared (IR) flammable gas and carbon dioxide (CO2) sensor designed for use in fixed point detection systems where conventional detectors can prove unreliable or suffer from interference and damage.
Conventional flammable gas 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 is totally immune to poisoning and will reliably warn of gas hazards in environments that are unsuitable for other types of sensor. 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.
Typical environments requiring flammable gas monitoring include petrochemical processing, water and sewage treatment and power generation. Continuous CO2 monitoring is common in food production processes, laboratories and brewing.
This new IR 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 IEXEx approved for use in hazardous areas, the Xgard IR 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.
