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 4–20 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.
