LEL-IR Sensor Behavior
The Non-Dispersive Infrared (LEL-IR) sensor detects combustible gases using infrared absorption. It is suitable for use in oxygen-deficient or inert environments.
The LEL-IR sensor exhibits the following key behaviors:
Operates without oxygen, making it ideal for inert or confined spaces.
Does not detect hydrogen (H₂) or acetylene (C₂H₂).
Resistant to poisoning, contamination, and electromagnetic interference.
Calibration must be performed in a flammable-free environment using appropriate span gas.
High-gas levels may temporarily affect readings, but the sensor typically recovers once gas clears.
- A-CART only operates in pumped mode, regardless of the configuration.
