SF6 Gas Leakage Monitoring Sensor FS02102 Introduction

SF6 Gas Leakage Monitoring Sensor FS02102 uses a unique NDIR technology without the need for light source and is equipped with an aluminum alloy shell. It adopts digital output, has the characteristics of anti-interference by other gases, no need for gas pump pipeline, small volume, sturdy and corrosion-resistant shell, easy to use and maintain, and adaptability to harsh environments. It is suitable for leak alarms, environmental detection, online monitoring, gas component analysis, and other applications. Using the non-dispersive infrared principle to detect the presence of sulfur hexafluoride gas in the air, when the infrared light passes through, the transmission intensity of sulfur hexafluoride molecules to a specific wavelength will be significantly weakened. The degree of attenuation is related to the gas concentration, and the relationship between the two follows the Lambert-Beer law.
