  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    The ammonia (NH 3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH 3 analyzers that perform measurements indirectly, NH 3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system and time delays in measurement.

  • Nondispersive infrared sensor - Wikipedia

    A nondispersive infrared sensor is a simple spectroscopic sensor often used as a gas detector. It is non-dispersive in the fact that no dispersive element is used to separate out the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors use a broadband lamp source and an optical filter to select a narrow band spectral region that overlaps with the absorption region of the gas of interest. In this context narrow may be 50-300nm bandwidth. Modern NDIR sensor

  • How infrared sensors measure LEL combustible gas | 2014-09-03

    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 concentration of the gas being measured. Optimizing instrument performance along one parameter usually requires a tradeoff along another parameter. Using an IR source that produces a brighter beam of light increases signal strength, but takes more power. Lengthening the optical path provides greater opportunity for the molecules to absorb the light, improving the sensor’s ability to measure gases with lower relative responses, while at the same time allowing use of a lower power IR source to achieve the same strength of signal. But it means the sens...
