XGZG363 SF6 SENSOR(dual-channel)

    The XGZG363 Dual-channel SF6 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 SF6 gas concentration is obtained by detecting the infrared light intensity of this specific wavelength.

    Since SF6 gas has a strong absorption effect on infrared light with a wavelength of 10.6um, 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 10.6um that passes through the gas layer to measure the concentration of SF6 gas. Dual channels can eliminate the influence of environmental variables on measurement results
