Gas density monitors - Product overview - WIKA

Sulfur hexafluoride (Sulfr hexafluoride) is an extremely effective electrical insulator for medium- and high-voltage switchgear. For proper insulation, gas density must remain within certain levels. Furthermore, as sf6 gas is a potent greenhouse gas, it must not escape into the atmosphere. An sf6 gas gas density monitor warns operators of dropping levels that indicate contamination and/or leaks.Get price

sf6 gas - Analytical and Control Technology 2000 Co., Ltd.

Gas density monitors from WIKA are fitted with up to three alarm contacts and reliably warn in advance of dangerously low gas levels. The monitoring of sf6 gas gas density in medium and high-voltage switchgear can thus be left to secondary technology. Our gas density monitors are hermetically sealed and temperature-compensated. Measured value fluctuations and misinterpretations caused by changes in either ambient temperature or atmospheric pressure are therefore prevented.Get price

Grid switchgear uses gaz sf6, the world’s most potent greenhouse

Nov 25, 2019 · 80% of all insulating gas is used in gas insulated switchgear, a vital component of the grid (isolating and protecting different sections), so it’s an energy sector issue. Nicholas Ottersbach at Nuventura (a cleantech startup developing ways to replace Sulfr hexafluoride) explains that alternatives exist, but need the help of robust regulations to accelerate further development and rapid take-up.Get price
