Displacements Schemes for Obtaining the Frequency Dependence on the Cottonseeds Moisture

The mathematic model of the high frequency moisture meter for cottonseeds has been constructed, in which the studying material as a complex dielectric installing in an electric field is represented. The displacement scheme which includes capacity between electrodes and also capacities and resistors corresponding to different polarization types has been presented. 4 variants of displacement schemes which describe approximately the dependence of angle tangency of dielectric losses on the electromagnet field frequency using in the measuring device have been considered. It has been shown that the simplest two element R-C scheme connected parallel corresponds to the closest real description of measuring object in frequencies range from 105 up to 108 Hertz.
