Abstract
A measuring device for determining the dielectric value of a medium in a phase-based manner comprises a measurement section which can be brought into contact with the medium, a signal generation unit for injecting a high-frequency signal at a defined frequency into the measurement section, and an evaluation unit designed to receive a corresponding reception signal after said high-frequency signal passes through the measurement section, to determine a phase shift between the high-frequency signal and the reception signal, and to determine the dielectric value of the medium on the basis of the determined phase shift. The measuring device also comprises at least one filter which transmits the frequency of the high-frequency signal and is arranged such that the received reception signal and/or the generated high-frequency signal is/are filtered. This ensures that the determined dielectric value is not distorted by noise caused by components or the environment.
