Abstract
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.
Claims12
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, comprising:
- 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;
- and
- 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,
- wherein the element is a line resonator with at least one end face that functions as an electrode, and wherein the line resonator has two end faces that function as electrodes and which are oriented toward the testing region.
