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.

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 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 over a large area ... More
