Crowcon ATEX gas sensors for flammable and toxic gases
The XGard Series of gas sensors are designed to meet your specific needs. The hazards of toxic and flammable gases and lack of oxygen are different for each type of application. XGard offers you three different sensor designs so you can choose the specific design to meet the needs of your site. XGard is available in explosion-proof, intrinsically safe, or safe area versions for use in any environment and for any classification.
XGard type 1: Intrinsically safe toxic gas and oxygen sensor
XGard type 2: Explosion-proof toxic gas and oxygen sensor
XGard type 3: Explosion-proof flammable gas sensor
XGard type 4: Explosion-proof flammable gas sensor at high temperatures
XGard type 5: Explosion-proof flammable gas sensor with a 4-20 mA output
XGard type 6: Explosion-proof gas sensor based on thermal conductivity
