Methane alarm Detector

The methane alarm detector detects gas concentration through catalytic combustion or infrared absorption principles. When the sensor comes into contact with methane, it generates changes in electrical signals, triggering audible and visual alarms upon reaching the set threshold. It is used in locations with methane leakage risks, such as gas pipelines, mines, and chemical plants, to ensure safety monitoring.
Selection
Ensure the detection range covers 0-100% LEL when selecting, with explosion-proof ratings meeting on-site requirements and including a sensor life indicator function. Prioritize models with a response time of less than 15 seconds, and choose diffusion or pump-suction sampling methods based on the installation environment. Calibrate regularly using standard gases.
