Abstract
The invention relates to a measuring device for determining the dielectric value of a medium. The measuring device is based on two waveguides, each of which has a signal gate on one end. The waveguides are, in such case, so arranged that the signal gates lie opposite one another. Formed therebetween is a sample space for the medium, such that a high frequency signal, which is in-coupled into the first waveguide, is transmitted into the second waveguide via the second signal gate after passage through the medium. Since the transmitted fraction and the reflected fraction of the high frequency signal depend strongly on the dielectric value, such can, as a result, be measured with a high sensitivity and, depending on choice of the frequency band and dimensioning of the waveguides, over a large value range.
