Catalytic Gas Detector: How Catalytic Bead Sensors Work ...

2017-10-02· Lower Explosive Limit (LEL) indicates the minimum concentration of gas in the air that will ignite and explosively burn if there is a source of ignition. The atmosphere will start burning under the following conditions: it must contain an adequate level of oxygen and fuel, a source of ignition, and the molecular energy sufficient enough to sustain the fire chain reaction. These four conditions ...

Why LEL important in Gas Detection? - Inst Tools

For a gas detector to give an alarm at 10% of the LEL, it must trigger when it detects % by volume. The detector for this application would most likely be calibrated for the range from 0% to 5% gas by volume, but display the reading as 0 – 100% LEL. Why LEL important in Combustible Gas Detection? When it comes to dealing with combustible gases, it is important for those doing so to have a ...

LEL and UEL Explained (Explosive Gas) - Projectmaterials

2017-09-20· The lower explosive limit (LEL) is the minimum concentration of a specific combustible gas required to fire combustion when in contact with oxygen (air). If the concentration of the gas is below the LEL value, the mix between the gas itself and the air is too weak to spark. The upper explosive limit (UEL) is the maximum level of concentration of the gas that will burn when mixed with oxygen ...
