XGZG362 CH4 SENSOR(dual-channel)

    The XGZG362 Dual-channel CH4 sensor adopts the principle of non-dispersive infrared (NDIR), which has the advantages of small size, long life, fast response, high precision, and continuous analysis.

    Non-dispersive infrared (NDIR) gas concentration detection technology uses the principle that gas molecules can absorb infrared light of a specific wavelength, but have no effect on other wavelengths of infrared light to detect gas concentration. The bandpass filter in front of the thermopile sensor is used to filter out infrared light outside a specific wavelength, and then the CH4 gas concentration is obtained by detecting the infrared light intensity of this specific wavelength.

    Since CH4 gas has a strong absorption effect on infrared light with a wavelength of 3.435um, and other gases have no absorption effect on infrared light of this wavelength, it can be performed by measuring the intensity of infrared light with a wavelength of 3.435um that passes through the gas layer to measure the concentration of CH4 gas. Dual channels can eliminate the influence of environmental variables on measurement results
