Dec 01, 2016 · Gaseous sensor system was developed for the detection of sulfur hexafluoride vapor based on its cataluminescence (CTL) emission by using coral-like Zn-doped SnO 2 composite. The test architecture, experiment characteristics and optimal conditions were studied in detail under optimized experiment conditions. Results showed that the gas sensor system covered a linear detection range from 8 mg/L to 5600 mg/L (R = 0.9963, n = 7) with a detection limit of 6.2 mg/L (S/N = 3), which was below the ...

  • Sulphur Hexafluoride | Edinburgh Sensors | Gas Detection

    Sulphur Hexafluoride. NDIR sensors for measuring SF 6 leaks. Sulphur hexafluoride is an inorganic, colourless, odourless, non-flammable gas which is an excellent electrical insulator. It is an extremely potent greenhouse gas therefore it is important to minimise leaks of it to the environment. It absorbs strongly in the infrared, so NDIR sensors are ideally suited to detecting it at low ppm concentrations.
