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 ...

A review on non-dispersive infrared gas sensors ...

Aug 01, 2016· Infrared spectroscopy is a technique based on the vibrations of the atoms of a molecule. An infrared spectrum is commonly obtained by passing infrared radiation through a sample and determining what fraction of the incident radiation is absorbed at a particular energy .As an application of infrared spectroscopy, non-dispersive infrared (NDIR) gas measurement started in the late 1930s in …

eSense Low-Temperature CO2 Transmitter |

The transmitter uses an IP65-rated housing with a built-in heater. The heater ensures that gas samples entering the CO2 sensors are not only warm enough for sensing but also at the correct moisture level. The CO2 levels are then read by the NDIR carbon dioxide sensor and transmitted via industry standard 0-10V or 4-20mA signals to an HVAC system.
