What is the principle of SF6 and oxygen monitoring unit of SF6 concentration online monitoring system?
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 concentration and oxygen content changes in the environment to output strong and weak electrical signals. After accurate compensation and amplification, the data is transmitted to the 32-bit digital signal processor (DSP). Through the digital model embedded in the DSP, the data is transported and compared. After the data is encoded and encrypted by the communication processing module in the digital transmission DSP, the data is transmitted to the field host through the CAN bus in the form of digital signals. The data results sent by the received SF6 and oxygen detection units as well as temperature and humidity detection units are decoded, analyzed and processed comprehensively.
