Function and system design Measuring principle Conductive measurement of conductivity AC The conductivity of liquids is measured with the following measurement setup: Two electrodes are immersed in the medium. An AC voltage is applied to these electrodes which generates a current in the medium. The electric resistance or its reciprocal value, the conductance G, is calculated according to Ohm’s law. The specific conductivity κ is determined using the cell constant k that is dependent on the sensor geometry. Conductive measurement of conductivity AC I U Power supply Current meter Voltage...

Reliability The Memosens technology digitalizes the measured values in the sensor and transfers them to the transmitter contactlessly and free from interference potential. The result: • An automatic error message is generated if the sensor fails or the connection between sensor and transmitter is interrupted. • The availability of the measuring point is dramatically increased by immediate error detection. Maintainability Sensors with Memosens technology have integrated electronics that allow for saving calibration data and further information such as total hours of operation and operating...
