<p>A method for online measurement of a plasticizer in an endless filter rod (7) at a filter rod maker, with the following method steps:
- measuring a resonance shift (A) and a line broadening (B) with a microwave resonator (10) at a passing endless filter rod (7),
- determining a mass per length of plasticizer from the measurement variables (A, B) of the microwave resonator (10),
- measuring (13) a reference mass of plasticizer applied per time with the application (4) of the plasticizer (17) 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 of the microwave resonator, over the same time period in which the reference mass of plasticizer is determined,
- determining a deviation between the averaged reference value for the mass per length and the averaged mass per length and correcting the mass per length, determined from the measurement variables of the microwave resonator, according to the determined deviation.</p> |
