Abstract
A measuring device for determining the dielectric value of a medium has at least the following components: a measuring sensor with at least one first electrically conductive electrode and a high-frequency unit which is designed to couple a high-frequency signal at least into the first electrode and determine the dielectric value of the medium using a corresponding reflection signal. The measuring device is characterized in that the first electrode is wound on a measuring rod which can be brought into contact with the medium. By winding the electrode, the measuring sensor can be advantageously configured to be significantly shorter without limiting the sensitivity of the measuring device. In this manner, the measuring device can also be used in the event of constricted installation conditions.
