SF6 gasplant Density Monitors for Hitachi

SF6 gasplant Density Monitors for Hitachi

The pressure of the SF6 gas varies with temperature, so a mechanical temperature-compensated pressure switch is used to monitor the equivalent of gas density. GIS is filled with SF to a density far enough above the minimum density for full dielectric and interrupting capability so that from 10 to 20% of the SF6 gas can be lost before the ...

  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 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.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.
