Non-Dispersive Infrared (LEL-IR)
Description of the LEL-IR sensor.
The Non-Dispersive Infrared (LEL-IR) sensor detects combustible gases using infrared absorption. It is suitable for use in oxygen-deficient or inert environments.
Note: The F2 LEL-IR Pump Cartridge only operates in pump mode, regardless of configuration.
The LEL-IR sensor:
- Does not detect Hydrogen (H2) or Acetylene (C2H2).
- Is resistant to poisoning, contamination, and electromagnetic interference.
- Must be calibrated in a flammable-free environment using appropriate span gas.
Note: LEL-IR
sensors are impacted by temperature. For more details, see Cartridges and Extreme
Weather.
