advantages of Sulfur Hexafluoride sensor

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.

    The same Report highlights sulfur hexafluoride (SF 6) as an important greenhouse gas, as it has a radiative forcing of 0.52 W/m 2, an atmospheric lifetime of 3,200 years and a Global Warming Potential (GWP) of 23,900. Sulfur hexafluoride is almost non-reactive and therefore it is widely employed for insulation and current interruption purposes in electric power transmission and distribution equipment.Cited by: 6

  • Sulfur Hexafluoride - an overview | ScienceDirect Topics

    Sulfur hexafluoride (SF 6) is an inert, volatile tracer and has been deliberately added to water bodies to determine k w. Experiments in enclosed lakes showed a good correlation between k w and wind speed and a parameterization of k w developed from these studies predicts a similar global mean (12 cm h −1 ) to that obtained from the radon data.
