New infrared flammable and CO2 gas sensor detects hazards where conventional sensors fail
The Xgard infrared (IR) from Crowcon (Figure 1) is a new, low-cost 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. IR 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.
