| 摘要 |
An apparatus for the measurement of mass and/or moisture of dielectric objects, with an analysing unit, at least one high frequency generator, at least one high frequency detector and with a high frequency resonator, wherein the at least one high frequency generator can generate at least two modes which are independent from each other, having different resonance frequencies in the resonator, the at least one high frequency detector can measure the occurring frequencies for each mode in the resonator, and the analysing unit can determine a shift of the resonance frequency (A) and a change of the resonance curve for the measured frequencies in each mode, and can calculate the mass and/or moisture of the dielectric object from the determined values for the shift of the resonance frequency (A) and the change of the resonance curve.
