How do you protect an LEL sensor from sensor poisons?

Chronic LEL Sensor Poisons • Hydrogen Sulfide • Halogenated Hydrocarbons (Freons, trichloroethylene, methylene chloride) • Styrene Also called “inhibitors,” chronic LEL sensor poisons don’t act as quickly on catalytic bead sensors. Often, exposure to clean air will allow the sensor to “burn off” these compounds. But when operated in an atmosphere containing these chemicals ...

Safety - What is %LEL / %UEL and PID and PPM? - Lower ...

Therefore, 100% of LEL is 14,000 ppm of gasoline, 10% of LEL is 1,400 ppm of gasoline and 1% of LEL is 140 ppm of gasoline. 140 ppm of gasoline is the lowest amount of vapor that the LEL monitor can "see." Gasoline has a TWA of 300 ppm and a STEL of 500 ppm; this does not make LEL sensors well suited for measuring gasoline vapors because they simply don't provide adequate resolution. LEL ...

What gases can the LEL sensor detect? - Honeywell

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 with a correction factor. Only the manufacturer can specify which gases the sensor can read and the expected reading level. In addition, it cannot detect all combustible gases; elemental hydrogen and acetylene ...
