New Infrared Flammable & CO2 Gas Sensor Detects Hazards Where Conventional Sensors Fail

Jan 01 2000 Read 1285 Times

Xgard IR from Crowcon (UK) 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 or temporary inhibition when exposed to gases such as hydrogen sulphide. 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 water and sewage treatment facilities. Continuous CO2 monitoring is common in laboratories.

This new IR sensor can be specified with two types of enclosure: polyestercoated 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 plugin module that makes replacement quick and easy. ATEX* 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.
