Measuring device

A method for measuring a dielectric value of a bulk material in a container, the method comprising:

• providing a measuring device for measuring the dielectric value of the bulk material in the container, including:
• a signal generating unit designed to drive a transmitter electrode by means of an electrical AC voltage signal such that the transmitter electrode transmits a radar signal in a direction of the bulk material;
• a receiver electrode arranged in the container to receive the radar signal after passing through the bulk material;
• and
• an evaluation unit configured to:
• ascertain an amplitude, a phase shift, and/or a signal propagation time between the transmitter electrode and the receiver electrode on the basis of the radar signal received by the receiver electrode, and
• determine the dielectric value on the basis of the ascertained signal propagation time, phase shift, and/or the ascertained amplitude,
• wherein the transmitter electrode and the receiver electrode each includes:
• a dielectric resonator layer, and
• a metallic reflection layer mounted behind the dielectric resonator layer with respect to each other electrode;
• emitting the radar signal via the transmitter electrode in the direction of the bulk material;
• receiving the radar signal via the receiver electrode after passing through the bulk material;
• determining the amplitude of the received radar signal and/or the signal propagation time between emission and reception of the radar signal;
• and
• determining the dielectric value by using the amplitude and/or the signal propagation time.
