Cigarette filter rod measuring station, has micro-wave measuring device measuring mass of softening agent, moisture content and/or dry mass of filter material, where device has resonator and measuring unit for determining resonance changes

摘要

The station has a measuring equipment for measuring mass and pulling resistance of a filter rod, and a micro-wave measuring device for measuring the mass of a softening agent and/or moisture content and/or dry mass of a filter material in the filter rod. The measuring device has a microwave resonator and a measuring unit for determining changes in resonance of the filter rod, where the measuring unit determines a shifting of a resonance frequency and a spreading of a resonance curve.
