Signal conditioning for NDIR sensor Application note

In the case of an NDIR CO. 2. sensor, the active channel is combined with a filter which allows the µm wavelength to pass, that is the quantity the CO. 2. molecule can absorb. The reference channel has a filter centered on µm where there is no absorption as described by (data are issued by HITRAN database). Figure 3. Absorption spectrum of CO. 2. Absorption spectrum of CO2 0 ...

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.

NDIR Gas Sensors Electrical Optical Components, Inc.

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 prefiltered. Instead a narrow bandpass (or NBP) filter is used before the detector. The NDIR sensor is a broadband IR detector using ...
