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.
Die E+E CO2-Sensoren basieren auf dem NDIR-Zweistrahlver-fahren (2 Wellenlängen / 2 Detektoren). Ein Detektor ist auf die Wellenlänge von 4,2 μm eingestellt, die von CO2 absorbiert wird. Der zweite Detektor ist auf eine Wellenlänge von 3,9 μm …
NDIR analyzers accommodate the analysis of a wide range of gases, including carbon dioxide (CO 2), carbon monoxide (CO), methane (CH 4), and sulfur dioxide (SO 2). Below we outline how NDIR analyzers are used to analyze these gases in different industrial applications. CO 2 Analyzers
