Gas density monitors

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 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. The instruments are manufactured entirely from stainless steel and, with this, ensure the highest quality.
