Description
Genuine Crowcon spare sensor assemblies for flammable gas detection in the Xgard fixed detector range — pellistor (catalytic) VQ-series assemblies, infrared (IR) spare sensor modules and thermal conductivity (TC) assemblies. Configurations cover methane, propane, butane, pentane, ethane, ethylene, LPG, petrol vapours, hydrogen, acetylene, ethanol, methanol, hexane, toluene, jet fuel and ammonia LEL, in 0-100% LEL and percent-volume ranges.
These are complete factory assemblies and modules, ready to swap into the detector — not bare sensing elements. Sensors are consumable parts: replace the assembly when the detector fails a bump test or calibration, drifts, or reaches end of life, and always bump test and calibrate after fitting. Pick the exact gas, sensor type and range in the Configuration dropdown.
