SF6 gas density monitors: reliable warning against low gas quantities

Sulfur hexafluoride (SF6) 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 is a potent greenhouse gas, it must not escape into the atmosphere. An SF6 gas density monitor warns operators of dropping levels that indicate contamination and/or leaks. WIKA’s SF6 gas density monitors are temperature compensated and hermetically sealed to shield measurements from atmospheric pressure fluctuations and differences in mounting level. Manufactured entirely from stainless steel for reliability and long life, they are fitted with up to three alarm contacts to provide advance warnings when pre-defined limit levels are reached.

What happens after the minimum validity of the WIKA Build ID has expired?

Validity cannot be guaranteed after three months.

After unpacking the gas density monitor, the pointer is not in zero position - is the instrument defective?

The instrument is probably not defective. The temperature compensation also works without a gas compartment being connected. Through this the pointer changes its position to compensate for the influence of the temperature on the indication. At temp ...
