Abstract
A method for measuring absorbent hygiene products comprises placing absorbent bodies on a web and moving the web through at least one microwave resonator. Values of a shift in a resonance frequency and a spreading of the resonance frequency are measured using the at least one microwave resonator to continuously determine the shift in the resonance frequency and the spreading of the resonance frequency. At least one of moisture and density of the plurality of absorbent bodies is determined based on the measured values of the shift in the resonance frequency and a spreading of the resonance frequency. Empty values for each of the measured values of the shift in the resonance frequency and the spreading of the resonance frequency are determined and subtracted from the measured values of the shift in the resonance frequency and the spreading of the resonance frequency to evaluate the measured values.
