How does an NDIR CO2 Sensor Work? |

How does an NDIR CO2 Sensor Work? January 05, 2021 NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.

Infrared absorption and emission spectra of carbon ...

The infrared absorption and emission spectra of carbon monoxidc and carbon dioxide have been measured with high resolution in the region from 4 to 6 microns. The measure­ ments of the Cl2016 fundamental band were carried out to a high precision, and a set of molecular constants were calculated from the experimental data. In emission the 1- 0 and 2-1 bands of CO were measured in the P branch ...

Carbon Dioxide Absorption in the Near Infrared

Carbon Dioxide is composed of a single carbon atom covalently bonded to an oxygen atom on either side. This structure allows for CO ... energy states, while longer wavelengths such as in the IR spectra match the frequency of vibrational states. 4 There are three general vibrations for a CO 2 molecule: a symmetric mode, a bending mode, and an asymmetric mode (Figure 1). Each mode is able to ...

The Infrared Absorption Spectrum of Carbon Dioxide

The complete infrared spectrum of C O 2 may consistently be explained in terms of a linear symmetrical model, making use of the selection rules developed by Dennison and the resonance interaction introduced by Fermi. The inactive fundamental ν 1 appears only in combination bands, but ν 2 at 15μ and ν 3 at μ absorb intensely.. Resolution of the fundamentals ν 2 and ν 3.—The 15μ ...
