  • Page 8: Inductive Conductivity Measurement

    3 Inductive conductivity measurement Range of Applications General The inductive measurement process allows a mostly maintenance-free acqui- sition of the specific conductivity even in difficult medium conditions. In con- trast to the conductive measurement process, problems like electrode replacement and polarization do not occur. Brief description The device is used for the measurement/control of the conductivity/concentra- tions of liquid media.

  • Page 9: Function

    3 Inductive conductivity measurement Function of the transmitter The device is conceived for use at the location. A robust housing protects the electronics and the electrical connections from aggressive ambient influences (system of protection IP67). In the standard version, the device has one analog signal input for the conductivity/concentration and the temperature.
