Two probes are immersed into the measured liquid. The distance between the probes and their surface define the cell constant (K) of the instrument.
Connecting AC voltage to the electrodes the electronics measures the conductivity of the liquid between the probes. This measured value is converted to 4…20 mA output signal.
The cell constant defines the measuring range and thus the application area
