Gas density sensors

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

Can a gas density sensor be damaged if connected to too-high a voltage?

Inadvertent connection of the voltage supply lines to the communication pins of the instrument can cause damage, since the connection pins for the communication have not been designed for high voltages.

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.
