Combustible Gas Detection Fundamentals

Lower Explosive Limit (LEL) or Lower Flammable Limit (LFL). This is the minimum concentration of a flammable gas or vapor that will propagate flame when exposed to a source of ignition. Commonly abbreviated LEL or LFL, a mixture below this concentration level is considered too “lean” to burn. An increase in atmospheric temperature or pressure will decrease the LEL of a gas or vapor. Nature ...

What gases can the LEL sensor detect?

The LEL Catalytic sensor reacts with almost all inflamable gases. A new unit is factory calibrated for CH4 but the sensor can be calibrated for any other inflamable gas or adjusted through a correction factor. The IR LEL sensor is designed primarily for a target gas ( Methane, Propane). It can detect a variety of gases with a greater or lesser degree of accuracy, but cannot be adjusted ...

Defining LEL (Lower Explosive Limit) For Calibration Gas

One hundred percent lower explosive limit (100% LEL) denotes an atmosphere in which gas is at its lower flammable limit. The relationship between percent LEL and percent by volume differs from gas to gas. The example below demonstrates the flammability of Methane (Natural Gas) in Air. In concentrations of 0-5% Methane in air, the mixture is too lean to ignite or burn. Methane concentrations ...
