Introduction to Gas Sensing Using NonDispersive Infrared ...

Nondispersive infrared (NDIR) is a physical sensing technique that provides a number of advantages over catalytic gas sensing method. The main feature of this technique is that fixed narrowband filters are utilized with separate IR detectors to detect a few gas absorption lines across a restricted wavelength range. This helps in eliminating the dispersive potion of a gas spectrometer. The ...

Nondispersive Infrared Sensor Assignment Point

The principle of nondispersive infrared absorption uses the properties of individual gases in absorbing specific frequencies of infrared light which the sample gas is exposed to. The main components of an NDIR sensor are an infrared (IR) source (lamp), a sample chamber or light tube, a light filter, and an infrared detector. An infrared …

09/05/2021· One technique is called nondispersive infrared (NDIR) spectroscopy. NDIR is usually used to measure a single constituent of an air sample. Think what the name implies and consider how such an instrument might be designed. The word nondispersive implies that the instrument does not use a monochromator. The design of a NDIR is illustrated in Figure \(\PageIndex{6}\). Common things that are often measured using NDIR …
