Fixed Methane Alarm

A fixed methane alarm detects methane concentration through catalytic combustion or infrared principles. When the sensor comes into contact with methane, it generates an electrical signal change, triggering audible and visual alarms upon reaching the set threshold. It is used for leakage monitoring in places such as gas stations and chemical plants.
Selection
When selecting, ensure the detection range covers 0-100% LEL and the explosion-proof rating meets on-site requirements. Prioritize catalytic combustion sensors for routine environments, and switch to infrared sensors for environments containing silicon compounds. Pay attention to the sensor lifespan and calibration cycle, and determine the wiring method based on the installation location.
