NDIR sf6 detection systems pdf

The IR series of infrared gas detection sensors use the technique of NDIR (Non Dispersive Infrared) to monitor the presence of SF6 and refrigerants. This technique is based on the fact that the gas has an unique and well defined light absorption curve in the infrared spectrum that can be used to identify the specific gas.

  • Nondispersive infrared sensor - Wikipedia

    A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
