TheYLE Motor Sensors working principle of CO2 sensor

The working principle of the CO2 sensor is: using the single beam dual wavelength non divergent infrared delta method, which is unique in the filter -- 1 kinds of pocket electronic tuning interferometer mirror it. This filter milling to ensure the accuracy and stability of YLE Automotive Temperature Sensors wavelength of light it through, to avoid the abrasion of rotary filter filter, the brake is not matching and traditional and generating problem arising. This paper is to discuss the optical measurement method of non divergent infrared measurement. A variety of gas will absorb light. Different gases absorb light of different wavelengths, such as CO2 to infrared light (wavelength 4. The most sensitive 26m). Carbon dioxide analyzer is usually measured gas inhalation of a measuring chamber, one end of the measuring chamber is provided with a light source and the other end is provided with the filter and detector. The filter's role is to allow only certain wavelengths of light through the. The YLE Coolant Temp Sensordetector is measured by the light flux measurement chamber. The luminous flux received by the detector was determined to in the environment of measured gas. Measurement method of non divergent infrared gas detection based on the principle of mainly has 3 kinds: single beam single wavelength measurement, the Shuang Guangshu dual wavelength and dual wavelength single - beam measurement. The implementation of Chinese sensor network transactions mainly talk about here in front of two kinds of measurement methods.
