  • Page 14: Measuring Principle

    3 System Description LB 571 BTwave Measuring Principle Microwaves penetrate the bulk material, causing a rotation of the free water mol- ecules. Placing a moist material on the field of the sensors causes a decrease of the resonance frequency and quality factor of the resonator. Both effects are measured and used as a direct indication of the moisture content.
