Methane gas sensor

Methane gas sensors detect methane concentration through catalytic combustion or infrared absorption principles. The catalytic type utilizes the change in resistance caused by methane combustion on the surface of a platinum wire, while the infrared type relies on the absorption intensity of methane for specific wavelengths of infrared light. They are used for gas leak monitoring, mine safety, and environmental detection.
Selection
When selecting, consider a detection range covering 0-100% LEL, explosion-proof rating suitable for the operating environment, catalytic type for routine detection, and infrared type for resistance to poisoning. Pay attention to a response time under 30 seconds, calibration cycle and sensor lifespan, and compatibility with existing alarm systems.
