METHOD AND DEVICE FOR MEASURING A DENSITY-INDEPENDENT MOISTURE VALUE AND A DENSITY VALUE OF DIELECTRIC MATERIALS FROM THE FREQUENCY SHIFTS OF TWO MICROWAVE RESONATORS OR TWO MODES OF A MICROWAVE RESONATOR

摘要

Method for measuring a moisture value F of dielectric materials using at least one microwave resonator, wherein a shift A in the resonant frequency is respectively evaluated for at least two resonant modes with different resonant frequencies and a moisture value which is independent of density is calculated from the measured shifts in the resonant frequency.
