DEVICE AND METHOD FOR DETERMINING THE PROPORTION OF AT LEAST ONE ADDITIVE IN A SUBSTANCE CONTAINING TOBACCO, AND TOBACCO-PROCESSING INDUSTRY MACHINE

摘要

The invention relates to a device for determining the proportion of at least one additive in a substance containing tobacco, comprising a sensor arrangement (29), which is arranged in a measurement relationship to the substance containing tobacco and is designed to operate with at least one electromagnetic alternating field having a first measurement frequency and a second electromagnetic alternating field having a second measurement frequency, which is different from the first measurement frequency, and for the output of signals that contain information from the interaction of the first and second electromagnetic alternating fields with the substance containing tobacco. The device comprises a data-processing apparatus (30), which is designed to determine, by evaluation of the signals from the sensor arrangement (29), two independent measurement parameters for each of the at least two measurement frequencies and to determine the moisture, the tobacco proportion, and the proportion of the at least one additive from the at least four determined measurement parameters.
