Gas density monitors - Product overview - WIKA

Sulfur hexafluoride (sf 6) is an extremely effective electrical insulator for medium- and high-voltage switchgear. For proper insulation, gas density must remain within certain levels. Furthermore, as Sulfr hexafluoride is a potent greenhouse gas, it must not escape into the atmosphere. An insulating gas gas density monitor warns operators of dropping levels thatGet price
