Device and method for measuring properties of a mobile material rod, in particular a cigarette rod, by means of a microwave resonator, which is fed with a single sideband signal

摘要

The device comprises a microwave measuring unit, which has a microwave resonator (54), through which a material strand is supported or conveyed. A microwave generator (71) is provided, which has a certain output frequency. The microwave resonator is impinged by a single-side band modulator (73) having a side band signal. An independent claim is also included for a method for processing and measurement of properties of a moving material strand of a tobacco processing industry.
