Tobacco dielectric constant measuring device - uses evaluation of amplitude values of HF signals received from 2 HF resonators along tobacco transport path

摘要

The device provides the complex dielectric constant of the tobacco using the tuning of HF resonators in the presence of the tobacco fed along a non- conductive guide sleeve (13) enclosed by the resonator housings (2,3). The HF transmitter and/or the resonators are controlled so that both resonators operate at the same frequency, with evaluation of the amplitudes of the received HF signals from both resonators via formation of sum and difference values to provide the complex dielectric constant.
