Summarize
NDIR infrared SF6 gas sensor module (WFS-S1-S) based on dual-beam dual-wavelength infrared measurement technology and high-precision digital processing technology, is widely used in high voltage switch GIS room SF6 gas leak monitoring (0-100ppm). SF6 gas leak detector (0-50ppm) and SF6 purity analyzer (0-100%). Internal integrated complete automatic drift control and temperature compensation circuit.
NDIR infrared SF6 gas sensor module (WFS-S1-S) adopts dual beam non-spectral infrared (NDIR) detection technology, which is resistant to other gas interference, easy maintenance, good stability, and built-in temperature compensation. Standard Modbus ASCII protocol, digital output and analog output optional and other advantages. Suitable for SF6 leak alarm, on-site construction protection, single gas analysis, online monitoring, industrial process analysis and other applications.
Product characteristics
The unique light-free cell NDIR technology is equipped with a highly breathable stainless steel housing and can be connected to an external oxygen sensor with a digital signal output. Because it is designed for SF6 specific wavelength, it is resistant to other gas interference, does not require air pump pipeline, small size, strong corrosion resistant shell, easy to use and maintain, can upload and output sulfur hexafluoride content and oxygen content at the same time, and is suitable for leak alarm, environmental detection, online monitoring, gas composition analysis and other applications.
