5100-28-IT Principle of Operation5100-28-IT Principle of Operation
• Combustible gases absorb IR light energy at defined wavelengths
• Higher concentration results greater absorbance
• Detector measures energy from the IR light and compares to the energy emitted by source
• Difference in energy received indicates level of gas concentration
