overview
SF6 Infrared Sensor (WFS-S1-S)Based on dual beam dual wavelength infrared measurement technology and high-precision digital processing technology, widely used in high-voltage switchesGISchamberSF6Gas leakage monitoring（0-100ppm），SF6Gas leak detector(0-50ppm)andSF6Purity analyzer(0-100%)Internally integrated with complete drift automatic control and temperature compensation circuits.
SF6 infrared sensor (WFS-S1-S) adopts dual beam non dispersive infrared(NDIR)Detection technology, with resistance to interference from other gases, easy maintenance, good stability, and built-in temperature compensation. standardModbus ASCIIThe advantages include optional protocols, digital outputs, and analog outputs. apply toSF6Various applications include leak alarm, on-site construction protection, single gas analysis, online monitoring, industrial process analysis, etc.
Product Features
Adopting a unique light free poolNDIRTechnology, equipped with a highly breathable stainless steel casing and an external oxygen sensor, using digital signal output. Due to targetingSF6Specific wavelength design, with resistance to interference from other gases, no need for air pump pipelines, small size, sturdy and corrosion-resistant shell, easy to use and maintain, adaptable to harsh environments, capable of simultaneously uploading and outputting sulfur hexafluoride content and oxygen content, suitable for applications such as sulfur hexafluoride leakage alarm, environmental detection, online monitoring, gas composition analysis, etc.
Compared with the principles of electrochemistry and negative corona discharge, infraredSF6Advantages of sensors:
