Gas density sensors

Featuring high-accuracy sensor technology and long-term stability

For high-precision online monitoring of the gas density, temperature, pressure and humidity of SF6 gas in internal and external systems of SF6 gas-insulated equipment, WIKA gas density sensors are exceptionally suited. The instruments are notable for their high-accuracy sensor technology which guarantees very good long-term stability and EMC characteristics. Optionally, there are hybrid solutions available which combine gas density transmitters with conventional gas density monitors with switch contacts.

FAQ
FAQ

Can a gas density sensor be damaged if connected incorrectly?

Interchanging the +/- connections cannot damage the instrument, since the connection pins for the voltage supply are protected against reverse polarity.

Why might the humidity measurement in a gas density sensor not show plausible values?

The measuring sensor settles, after commissioning, to the correct measured value. Depending on the initial conditions, this can take up to two days.
