Abstract
A conductivity sensor for measuring the electrical conductivity of a liquid medium having at least a first coil, a current source and a control and evaluation unit, the current source being connected to the first coil. The conductivity sensor has the ability to determine a particularly large range of electric conductivity by at least a first electrode and a second electrode and at least one voltage measuring unit being provided, the voltage measuring unit being connected to the first electrode and the second electrode, the control and evaluation unit being connected to the current source and to the voltage measuring unit, and the first electrode and the second electrode being out of electrical contact with the first coil.
