Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( 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.

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

The maximum NDIR chop frequency is 5 Hz, and the minimum half cycle pulse width is therefore 100 ms. The settling time to 22 bits is approximately × the minimum chop pulse width. The AD8629 has a Hz to 10 Hz input voltage noise of μV p-p. Ignoring the sensor voltage noise and the AD8629 current noise, a 1 mV p-p signal output from the thermopile yields a signal-to-noise ratio ...

IR-8400DC Gas Analyzer

The Infrared Industries NDIR-based IR-8400DC (compensated) total hydrocarbon (THC) gas analyzer is specially designed to measure CH4 (methane) in addition to the full range of hydrocarbons. This allows the analyzer to distinguish a discrete CH4 value to either be read separately from the THC reading or subtracted from it. The benefit here is the CH4 being a naturally occurring hydrocarbon is ...

Methane (CH4) Analyzers | Nova Gas | Methane Measurement

Methane Gas Analysis. Methane is a gas of interest in many analytical applications. Non-dispersive infrared (NDIR) analyzers can be used to measure CH4 gas because it is an excellent absorber of infrared energy. Methane in industry is frequently measured in percent (%) ranges, but parts per million (ppm) measurement is also possible with IR detectors.
