The LEL (Lower Explosive Limit) Gas Sensor Transmitter is used to detect the presence of flammable gases like methane, propane, or hydrogen in the air. It continuously monitors gas concentration levels and alerts if the gas reaches a dangerous level. It uses a catalytic bead or infrared sensor, provides 420 mA or RS485 output, and can be connected to control panels or alarms. Suitable for industrial plants, gas storage areas, and chemical factories, this device ensures safety by helping prevent gas explosions.
LEL stands for Lower Explosive Limit. It is the minimum concentration of a flammable gas in air that can ignite.
It can detect flammable gases such as methane (CH), propane, butane, hydrogen, and LPG.
It uses a catalytic bead or infrared sensor to measure the concentration of combustible gases and sends real-time signals to control systems
Standard outputs include 420 mA analog and RS485 Modbus digital for easy integration with SCADA or PLC systems.
Yes, flameproof/ex-proof models are available for Zone 1 and Zone 2 classified areas.
The transmitter can be connected to external audible/visual alarms through relay output or gas controllers.

Hydrogen Gas Sensor Transmitterincorporates a pellistor or catalytic bead sensor. This sensor consists of a matched pair of elements, one active and the other for compensation. When in contact with a combustible hydrocarbon or solvent causes the gas or vapor to "burn" or oxidize at concentrations below the Lower Explosive Limit (LEL). This oxidization process raises the temperature of the active bead and increases the resistance of the internal wire coil. The second bead does not have the catalytic coating and provides compensation for environmental conditions including temperature and humidity. When these elements are connected to the circuit, a useable signal is produced that is proportional to the gas concentration . Applications :
