A review on non-dispersive infrared gas sensors ...

Aug 01, 2016 · The detection limit of a NDIR sensor is a function of both IR signal strength (or sensitivity) and signal stability (signal-to-noise ratio). The detection limit has a concentration unit such as ppb, ppm, μg/m 3. The precision (%) of a NDIR sensor shows the consistency of results when repeated.

Infrared Measurement Principle (NDIR) - ecom

A non-dispersive infrared sensor is used in gas analysis to determine the gas concentration. NDIR analysers are particularly suitable for the determination of the concentration of carbon monoxide, carbon dioxide or hydrocarbons in a gas. Components of this process are a source of infrared radiation, an irradiated tube (cuvette) with the gas to be analysed, […]

Basic Principle of NDIR Gas Detection - Heimann Sensor

Thermopiles (in combination with an infrared light source) can be used to measure the gas concentration of certain gases. The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law.

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector. It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) 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 reg…
