Abstract
The complex dielectric constant of successive increments of a stream of tobacco particles is indicative of the mass and/or moisture content of the tested increments. Instead of passing along two high-frequency resonators, as disclosed in German patent No. 43 42 505 to Stange, the stream is caused to pass through the inlets and outlets of the housings of two high-frequency resonators which are connected to a microwave generator and transmit high-frequency signals whose amplitudes are indicative of the complex dielectric constants. The signals from the two resonators are processed in a regulating unit wherein a circuit sums up the real and the imaginary parts of the complex dielectric constant.
