Abstract:
1. A measurement device for measuring moisture from a material by electromagnetic radiation, wherein the measurement device comprises: a closed material space; a resonator with a first resonator part and a second resonator part, the resonator parts being aligned with one another, the material space being between the resonator parts and the material to be measured being insertable into the material space; the resonator parts comprising a generating element in the first resonator part and a detecting element in the second resonator part, the generating element and the resonator parts generating a resonating electric field which is vertical in the resonator parts and laterally omnidirectional in the material space; and a signal processing unit configured to determine a moisture content of the material based on a resonance frequency of an electromagnetic omnidirectional waveform resulting from the resonating electric field.
