Basic Principle of NDIR Gas Detection - Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: ... To generate more IR radiation, more electrical power is needed and this will also have a negative impact on the IR source lifetime. Therefore in most cases a bigger thermopile chip is the preferred choice if more signal is needed. It is also possible to detect different gases at the same time. In this case ...

NDIR Gas Sensors - Electrical Optical Components, Inc.

Nondispersive Infrared Gas Detectors An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not pre-filtered. Instead a narrow bandpass (or NBP) filter is used before the detector.
