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 ...

How does an NDIR CO2 Sensor Work? |

+

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. The IR light detector measures the amount of IR light that ...
