High-frequency moisture meter for grain and grain products
https://doi.org/10.32446/0368-1025it.2022-4-65-71
Abstract
The technical aspects of the construction of devices for measuring the moisture content of grain and products of the agroindustrial complex have been studied. The necessity of developing primary moisture measuring transducers has been substantiated. The dielcometric method for determining humidity, based on the dependence of the dielectric constant of the controlled material on its humidity, is considered. The dependencies linking the electrophysical parameters of materials with humidity and uninformative parameters of materials are studied. A structural diagram of a high-frequency moisture meter is presented, the principle of operation of which is based on the dielcometric method of measuring the moisture content of materials. A prototype of a grain moisture control device has been developed with an electrical model of the primary measuring transducer. The proposed high-frequency moisture meter can be used to measure the moisture content of grain and grain products in industrial and laboratory conditions.
