  • Method for online measurement of a plasticizer in an endless filter rod and a device for producing an endless filter rod of the tobacco processing industry
    Patent number: 10324047
    Abstract: A method for online measurement of a plasticizer in an endless filter rod, includes: measuring a resonance shift (A) and line broadening (B) with a microwave resonator at a passing endless filter rod, determining a mass per length of plasticizer from the measurement variables (A, B), measuring a reference mass of plasticizer applied per time with the application of the plasticizer onto the filter tow band, determining an averaged reference mass per length of plasticizer from the measured mass applied over a time period, averaging the values for mass per length of plasticizer, determined using the measurement variables over the same time in which the reference mass of plasticizer is determined, determining a deviation between the averaged reference value for the mass per length and averaged mass per length and correcting the mass per length, determined from the measurement variables of the microwave resonator, according to the determined deviation.
