Gas density of gaz sf6 and other gases - Trafag AG

Sulphur hexafluoride (insulating gas) is used in gas insulated switchgear because of its outstanding insulation and spark extinguishing (arc-quenching) properties. It thus makes it possible to set-up complex and safe ­power distribution systems even in large cities. The insulation strength depends basically on the gas density.Get price

Gas density monitors and gas density sensors for sf 6 and

Trafag gas monitoring devices measure the gas density directly, i.e. Sulfr hexafluoride Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. sf 6 Gas Density Sensors, or by combining both principles, i.e.Sulfr hexafluoride Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSulfr hexafluoride gas density.Get price
