Abstract

The invention relates to a method for determining the material moisture of a material, comprising the following steps: referencing a material using a referencing device by determining the material moisture of a material sample of the material in accordance with the mass of the material sample; determining the dielectric material constant (DProbe) of the material sample in accordance with the material moisture; calibrating a first microwave sensor using the dielectric material constant of the material sample; measuring the dielectric material constant of the material online by means of the first microwave sensor; determining the material moisture of the material using the dielectric material constant previously measured online.
