Microwave resonator housing passed by a filiform material with electronic components like the microwave generator being contained within shielded chambers of the housing

摘要

The microwave rod measuring device (20) has a housing (21) with an inner space that is formed as a microwave resonator. The inner space is enforced by a material rod. One or multiple accuracy determining electronic components is or are arranged within the housing. A microwave generator or a frequency-stabilized oscillator or a signal processing components or measuring electronic components are arranged as accuracy determining electronic components in the housing. A protective tube is made of a non-conductive material, particularly polyether ether ketone. An independent claim is included for a machine, particularly rod making machine or tobacco rod machine or filter rod machine, for tobacco processing industry.
