The SF6 and oxygen sensing components of the Winfoss SF6 concentration online monitoring system (WINFOSS-S1) use dual beam non-spectral infrared (NDIR) detection technology, which is resistant to other gas interference, easy maintenance, good stability, and comes with temperature compensation. Standard Modbus ASCII protocol, digital output and analog output optional advantages, and thermal pyrolysis technology and oxygen anode and cathode REDOX reaction, release electrons to form a current, with

SF6 gas decomposition products detection items include: SO2, H2S, CO and CF4 content detection. SF6 gas decomposition products detection methods include: electrochemical sensor method, gas chromatography, ionization method, dynamic ion method and infrared method. The electrochemical sensor method works by means of an electrical signal that reacts with the measured gas and is generated in direct proportion to the gas concentration.

Density is a measure of the specific gravity of SF6 gas in a closed container, which is independent of pressure and temperature changes. That is, the gas in the container does not leak or add gas into it, and its density state is constant. The internal pressure will change with the change of the ambient temperature.
