Measurement device for determining dielectric constant and conductivity

A measurement device for a determining dielectric constant and an electrical conductivity of a fill substance, comprising:

• a first electrode that can be brought into galvanic contact with the fill substance;
• a second electrode that can be brought into galvanic contact with the fill substance;
• a high frequency measuring unit that is designed to couple via a high frequency output an electrical high frequency signal into the first electrode, to receive via a high frequency input the high frequency signal from the second electrode after interaction of the high frequency signal with the fill substance, and to determine at least based on the received high frequency signal the dielectric constant of the fill substance;
• a conductivity measuring unit that is designed to couple via a signal output a measuring signal into one of the electrodes, to couple via a signal input the measuring signal out of the other electrode after interaction of the measuring signal with the fill substance, and to determine the conductivity of the fill substance based on the out-coupled measuring signal;
• and
• a signal decoupling unit that is designed to separate the signals of the high frequency measuring unit and the conductivity measuring unit from one another.
