A resonator device for testing a material quantity in the tobacco-processing industry for existence of at least one foreign substance and/or for detecting at least one of weight, density and humidity level of the material includes a resonator housing having a through opening for the material to pass through and a testing region located inside the resonator housing to which the material can be moved at least in part. The device has at least one element that increases energy density of electromagnetic waves for increasing the energy density in at least a portion of the testing region.

Microwave-resonator and measuring device

Apparatus for ascertaining the mass and/or the moisture of succesive increments of a running rod containing tobacco and/or filter material for tobacco smoke having a resonator housing with a cylindrical internal chamber which is disposed between and inlet an outlet and wherein the rod is exposed to microwaves. The horsing is made of a metallic material having a low thermal expansion coefficient, and its internal surface is lined with gold or another corrosion resistant substance. A protective plastic tube establishes a path for the rod from the inlet, across the chamber and into the oulet of the resonator housing.

Method and apparatus for applying microwaves to measure the moisture content of material

A stray-field sensor for measuring dielectric properties of substances includes generating elements for generating an electrical field and shielding elements for shielding the generated electrical field. The shielding elements have at least two openings for coupling the electrical field out into the outside space so that the electrical field is at least partially located outside of the shielding elements.
