ABSTRACT:
A device for testing the quality of rope-like materials in the form of yarns, rollings, fiber bands and the like employs a microwave resonator and devices for determining the displacement of the resonant frequency and the widening of the resonance curve due to the rope-like material present in the microwave resonator. Mechanical devices are provided for transporting the rope-like materials through the measuring volume of the microwave resonator. The microwave field is homogeneous in the measuring volume and the measuring device is a microwave generator constructed for measuring the mass per length and the moisture of the rope-like materials. Sensitivity of the device is improved by using metallic elements to concentrate the electromagnetic field in the measuring volume.
