CH4 (LEL) Sensor

LEL 90 is a flameproof flammable gas detector for Zone 1 and Zone 2 hazardous areas. It detects flammable gases up to the Lower Explosive Limit (LEL) of the calibrated gas (e.g., methane). Used in oil & gas and many other industries (chemical, petrochemical, power, manufacturing, utilities, waste treatment), it features a modular stainless-steel housing certified Ex d IIC T6. An integrated amplifier powers the pellistor sensor and provides a standard 4–20 mA output for control and monitoring systems.
