A comparative analysis of amplitude and phase methods for measuring the moisture content of materials in the grain drying process flow

Assessment and comparison of the error in determining the moisture content of materials by the amplitude and phase superhigh frequency methods are considered. It has been revealed that when the mass of the controlled material is not constant, the error of the amplitude method is smaller than that of the phase one. As a result of the investigations, to control the moisture content of materials in a process fl ow, it is recommended to use the amplitude method of measurements.
