Measuring Principle
A generator (1) generates an alternating magnetic field in the primary coil (2) which induces a current in the
medium (3). The strength of the induced current depends on the conductivity and thus the ion concentration
of the medium. The current flow in the medium generates another magnetic field in the secondary coil (4).
The resulting current induced in the coil is measured by the receiver (5) and processed to determine the
conductivity.
