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

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.

Why would the gas density sensor not provide plausible values, even after two days?

If the gas density sensor does not provide plausible readings, even after two days, it is recommended that you check the installation. The sensor should be installed as close to the gas compartment as possible and should be in contact with the gas ov ... More ...
