The Beer-Lambert LawWhat Is The Wavelength Used For Measurement?Limitations of Catalytic Wheatstone Bridge Type Lel SensorsAdvantages of Ndir Lel SensorsLimitations of Ndir SensorsThe strength of the NDIR sensor signal is determined by the Beer-Lambert Law, a basic law of physics. According to Beer's Law, the strength of the signal is proportional to (1) the intensity of the beam of infrared light; (2) the specific absorbance characteristics of the molecules of gas in the optical sensing chamber; (3) the distance the light travels through the sensing chamber (the optical path length); and of course, (4) the actual concentratio…See more on ishn.com[PDF]MSA Gas Detections7d9.scene7.com/is/content/minesafetyappliances/0700-58-MC PAIR vs NDIR - ENe The gas molecules heat and cool as they absorb the infrared energy. The pressure changes as a result of the heating and cooling of the molecules measured by the detector. r The gas is exhausted and a fresh sample enters the cell. This sampling process is continuously repeated. w The gas is irradiated with pulsed infrared energy. The pressure
