SF6 Gas Dehydration System That Doesn't ... - WIKA Blog's Innovative Dehydrator Removes Moisture from SF6 Gas Without Stopping Operations 05/03/2019 | Leo Lopez Pure SF 6 is an excellent insulator in electric switchgears, but humidity in the gas decreases its insulating ability and can also result in very harmful decomposition products for humans, machinery, and the environment.
Gas density monitors and gas density sensors for SF6 and ... 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.
