Method and device for measuring mass and/or moisture of the content of capsules

Method for measuring the mass and/or moisture of the contents of capsules containing products, with the aid of microwaves, in which method the displacement of the resonant frequency and broadening of the resonance curve caused by the capsules in at least two resonators is determined and evaluated, a first resonator with a measuring field which is homogeneous over the capsule dimensions being used to determine the total mass/moisture of the capsule, characterised in that a second resonator, having a measuring volume which is so severely limited that only the capsule casing can be detected therewith, is used.
