  • SO2 emission measurement with the European standard reference

    for all tested P-AMS except for NDIR at the lower range. The SO 2 results measured with NDIR and the chiller were lower compared to the set-up with NDIR and permeation. This was most probably due to the chiller causing absorption of SO 2 in the condensate. Tests were also carried out at field conditions, measuring the SO

  • 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.

  • Operating principle ‐NDIR-type gas sensor

    Structure of Ndir Gas SensorOperating PrincipleFeaturesWhen infrared radiation interacts with gas molecules, infrared light is absorbed by the gas molecules at a particular wavelength, causing vibration of the gas molecules. NDIR (Non-Dispersive Infrared) gas sensors detect decrease in transmitted infrared light which is in proportion to gas concentration. This transmittance, the ratio of transmitted radiation energy to the incident energy, is dependent on target gas concentration. NDIR gas sensor consist of an infrared source, detector, optical filter, gas cell, and electronics for signal processing. A single light source, dual wavelength type gas sensor has two detectors and two optical filters of different wavelengths which are placed in front of each detector. Infrared light that is absorbed by a target gas passes through the active filter with a particular bandwidth for the detection of the target gas. Infrared light that does not interact with the target gas passes through the reference filter. The difference between transmitted l...

  • CO2 Sensors: Which Type Should You Be Looking For?

    Non-Dispersive Infrared (NDIR) SensorsElectrochemical SensorsMetal Oxide Semiconductor (MOS) SensorsWhat Sensor Does The Laser Egg+ CO2 use?Simply put, NDIR sensors use specific wavelengths of light to measure the amount of CO2 in the air. Each element on Earth absorbs certain types of light. For example, a carrot will reflect orange light but absorb all of the other colors. Because the light is absorbed, it doesn’t have a chance to make it to our eyes to see. When things are broken down into atoms and molecules, we can pinpoint what kind of light each absorbs, even light that we cannot see. With this knowledge in hand, we can use sensors to test if certain elements are present and, if so, in what quantity. Carrots absorb green, blue, and violet light but reflect orange light. This is how a CO2 NDIR sensor works: Air will enter the sensor. The sensor will then activate a light set at one of the specific wavelengths for CO2, usually around four microns, at one end of the sensor. The other side will hold a receptacle that will measure how much light makes it to the other side. Once the light is activated, any CO2 in the a...
