8220 Conductivity Sensor
Brand: Burkert Fluid Control Systems
The conductivity sensor is a compact probe with integrated conductivity electrodes. Four conductivity probes having different cell constants are available and offer a large measurement range.
The Pt1000 for automatic temperature compensation is integrated in the sensor housing. The sensor transmits directly a raw signal and is fitted with a standard EN 175301-803 plug connector.
The sensor has to be connected to the Burkert conductivity transmitter Type 8225 for panel or wall mounting or to the multiCELL transmitter/ controller Type 8619 via a shielded cable (maximal cable length of 10 meters).
Features- Compact version for DN15 to DN200
- Large capabilities of conductivity measurement through different cells
- Large range of process connections with various fittings
