A: The Infrared sensor is expensive to
manufacture, but offers the following advantages:
- Totally immune to silicone poisons and halogenated compounds which can degrade or destroy
Catalytic/Pellistor Sensors.
- Infrared sensors are not damaged when exposed to high concentrations of combustible gases.
- Additionally, the Infrared sensor does not require a background of Oxygen in order to accurately
detect the combustible gas levels when there’s a need to inert or purge lines or vessels.
