METHOD AND APPARATUS FOR MOISTURE SENSING USING MICROWAVE TECHNOLOGIES

摘要

This invention provides a method and apparatus for the sensing of moisture using microwave technolgy. The apparatus provides a wave guide having a linear array of slots in its broadwell. A detector detects microwave reflection coefficients at the slots once the material is positioned over said slots to provide a value for the moisture content of the material. These slots are at an angle with respect to the longitudinal axis of the wave guide and the angle can be varied according to the material being tested.
