Abstract

This article discusses methods for measuring moisture content of certain substances and mate- rials. Currently, the most used methods, which is based on measuring the dielectric permittivity of the material. The dielectric permittivity of materials depends on its physical nature. The free dipole moment of polarized water molecules is much higher than the dipole moment of unstable molecules of minerals and oxides, this feature will allow us to judge the moisture content of substances. Measurement ɛ leads to a change in the capacity of the object under study, which can be regarded as an element of an equivalent electric circuit.The main advantages of the dielcometric method for determining the moisture content of mate- rials are listed.
