CO2 measurement with NDIR co2 sensors

Measuring method. The E+E CO2 sensors feature the dual wavelength/dual detector NDIR principle. One detector is tuned to µm wavelengths, which is absorbed by CO2, the second detector on µm, which is not affected by any gas. For every single measurement the CO2 concentration is calculated from the outputs of the two detectors.

OnChip NonDispersive Infrared CO2 Sensor Based On an ...

Typically, NDIR CO2 sensors use the strong absorption of CO2 around m, a wavelength range where no other common molecules absorb, thereby avoiding crosssensitivity issues. Due to these advantages, 83% of the European advanced CO2 sensor market uses NDIR sensors [4]. However, NDIR sensors tend to be bulky as a long (typically several cm) interaction length is required to …

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 ...

Nichtdispersiver Infrarotsensor – Wikipedia

Ein nichtdispersiver Infrarotsensor oder NDIRSensor ist ein spektroskopisches Gerät, das überwiegend als Gassensor eingesetzt wird. Besonders geeignet sind NDIRAnalysatoren zur Bestimmung der Konzentration von Kohlenstoffmonoxid, Kohlenstoffdioxid oder Kohlenwasserstoffen in einem Gas. Ein typisches Anwendungsgebiet ist die Analyse der Abgase von Verbrennungsmotoren.
