Photoacoustic-Based Gas Sensing: A Review

· NDIR sensors at the time and still today show cross sensitivities to a large number of gas species because of the broad spectral response of solid-state-based light detectors. To overcome this drawback, first Schick in the 1920s and then Veingorow, Luft, and Lehrer realized the potential of using the target gas itself as the filter medium since it features near-identical spectral ...

Nichtdispersiver Infrarotsensor – Wikipedia

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

A Miniaturised, Fully Integrated NDIR CO2 Sensor On-Chip

In this paper, we present a fully integrated Non-dispersive Infrared (NDIR) CO2 sensor implemented on a silicon chip. The sensor is based on an integrating cylinder with access waveguides. A mid-IR LED is used as the optical source, and two mid-IR photodiodes are used as detectors. The fully integrated sensor is formed by wafer bonding of two silicon substrates.

Messwissen von Testo | CO 2 | Testo SE & Co. KGaA

Die von Testo angewandte Messtechnik beruht auf dem NDIR (Nichtdispersives Infrarot) - Absorptionsprinzip. Bei diesem Messprinzip wird die Konzentration des gesuchten Gases elektrooptisch über das Ausmaß der Absorption einer spezifischen Wellenlänge im infraroten Spektrum gemessen. Die Abfolge ist wie folgt: Die Glühbirne sendet Strahlung aus. Das CO 2 absorbiert Strahlung bei …

CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 molecule counts. The industry calls this "drift". To combat sensor drift, during ...
