Infrared IR Sensors
Infrared detectors are based on the principle of infrared absorption by gas molecules
at specific wavelengths in the infrared region. The Mil-Ram sensor utilizes
an infrared lamp source and dual detectors; active and reference. The active
detector is covered by an optical filter that allows transmission of infrared
radiation at a specified wavelength where the target gas is known to absorb.
The reference element is covered by a filter that transmits wavelengths outside
the absorption band. This arrangement provides compensation for normal changes
in lamp intensity over time. The infrared detector can be supplied for hydrocarbon
(LEL) or carbon dioxide measurement. Unlike catalytic sensors for hydrocarbon
detection, the infrared sensor is unaffected by catalytic inhibitors and poisons.
