Combustible Gas Concentration Analyzer

The combustible gas detector measures the concentration of combustible gases in the air using catalytic combustion or infrared absorption principles. The sensor converts the gas concentration into an electrical signal, which is processed by the circuit to display the value and trigger audible and visual alarms. It is used for leakage monitoring and operational safety protection in settings such as petrochemical plants and coal mines.
Selection
When selecting, consider matching the sensor type to the types of gases being detected. Catalytic combustion sensors are suitable for most flammable gases, while infrared sensors are suitable for oxygen-deficient environments. Ensure the measurement range covers the safety limits, and the response time meets monitoring requirements. Pay attention to the explosion-proof rating and ensure it matches the hazardous area on-site. Regular calibration and maintenance are essential to ensure data reliability.
