Basic Principle of NDIR Gas Detection - Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: On the right side we have an IR light source that emits radiation at all wavelengths. The reflector is used to direct as much light as possible in the direction of the thermopile detector which is on the left side. In between there is a tube with IR reflecting walls which is used as measurement path. For CO2 ...

Carbon Dioxide Sensor -

NDIR sensors are spectroscopic sensors that detect carbon dioxide in a gaseous environment by its characteristic absorption. It includes an infrared detector, an interference filter, a light tube and an infrared source. The gas is either pumped or diffused into the light tube, and the electronics measure the absorption of the wavelength of light.

What is NDIR ? | CO2 Sensors | PRODUCTS | Asahi Kasei ...

Photodiode (Infrared sensor of NDIR CO2 sensor) Since the photodiode is a photo type detector, its response speed is overwhelmingly faster (typ. 2μs) than that of a thermal type detector. Therefore, by incorporating this photodiode into a NDIR gas sensor and combining with LED of an infrared light emitter, the power consumption can be reduced to the minimum.

Why NDIR? | Senseair

Why NDIR? A non-dispersive infrared (NDIR) sensor has a detector that measures how much infrared light of a specific wavelength is absorbed by the surrounding air. This measurement is then used to calculate the concentration of a specific gas. ›. Compared to electrochemical sensors, the lifespan of the NDIR sensor is lengthy.

Nondispersive infrared sensor - Wikipedia

NDIR Definition: NDIR stands for Non-Dispersive InfraRed. This technology is used to measure the concentration of a gas (actually, the number of molecules in the optical path) by determining how much infrared energy is absorbed at a select wavelength band that corresponds to a resonant mode spectrum of the molecule being analyzed.
