摘要： A system for measuring the moisture content of a multi-layer bale of material, comprising a source of microwave radiation disposed on a first side of the bale for directing a circularly polarized source beam through the bale in a direction substantially parallel to the layers thereof so as to exit from the bale as an exit beam and a conveyor for conveying the bale past the source of microwave radiation. A pair of microwave antennas are disposed on an opposite side of the bale for receiving mutually orthogonal components of the exit beam permitting determination of a maximum amplitude of the exit beam corresponding to an amplitude of the exit beam in a direction normal to the layers of the bale. This permits calculation of an attenuation of the beam consequent to absorption by moisture in the bale and thus allows the moisture content of the bale to be determined.

摘要： A method for highly accurate, high speed, multi-slice density and moisture content measurements and calculations of homogeneous or non-homogeneous fibrous material, using a microwave resonator device and computer algorithms. The device is comprised of a cylindrical microwave resonator, including two cutoff waveguides, internal corrective pieces, a teflon tube, signal input and output ports, alternative microwave sources, alternative signal receivers, temperature sensor and optional moisture sensor, and computerized processing and display units. The method comprises passing fibrous material, located in-line of a production process, through the resonator, wherein the fibrous material is scanned with a sweeping range of microwave frequencies, in a continuous, real time, and multi-slice mode. The presence of the fibrous material causes resonance frequency shifts and changes in resonator quality, which are proportional to, and used in calculations of, material density and moisture content, respectively. Calculations of material density (and moisture content) are based on evaluation of density and moisture content arrays (of time samples), which are functions of resonator frequency shift and quality data, empirically determined density, moisture content, and structurally dependent correlation functions, and material temperature. Improved accuracy in values of density is obtained by compensating for moisture content. Density and moisture content values are used for real time quality control feedback of process parameters, including fiber density, moisture content, temperature, and incoming feed rate.
