Abstract
The present disclosure relates to a method for determining a conductivity value of a measurement medium using a conductivity sensor. The method includes providing a conductivity sensor with at least one transmitting unit, at least one receiving unit, and a control unit having a storage module, and transmitting a stimulation signal into the measurement medium at the transmitting unit by the control unit. The method also includes receiving a detection signal at the receiving unit, determining a signal quality indicator by the control unit based on the detection signal, and determining a conductivity signal corresponding to the detection signal. The method further includes storing the conductivity signal, determining a dynamic factor by the control unit based on the conductivity signal, filtering the conductivity signal using a filter function depending on the determined signal quality indicator and the dynamic factor, and outputting a filtered measured value of the filtered conductivity signal.
