СИСТЕМА ВИМІРЮВАННЯ ВМІСТУ ВОЛОГИ ЗЕРНА З РОБАСТНОЮ ФУНКЦІЄЮ ПЕРЕТВОРЕННЯ, ІНВАРІАНТНОЮ ДО ЗМІНИ ФІЗИКО-ХІМІЧНОГО СКЛАДУ ЗЕРНА

Abstract

The main task was to receive a robust transfer function for the capacitive grain moisture measurement system. It was estimated how the new transfer function compensates for the type uncertainty and how close it is to the nominal values of moisture content. Dispersions of adequacy and repeatability of the new transfer function, which describe possible variation in the measured moisture values and the correspondence of the new transfer function with the nominal linear transfer function of a moisture meter respectively, were calculated for five chosen substances. It was proved that the new transfer function has lower sensitivity to grain type and better adequacy to the ideal transfer function than the closest analog.
