METHOD OF DETERMINING MOISTURE CONTENT OF SUBSTANCE Russian patent published in 2012 - IPC G01N22/04 

FIELD: physics.

SUBSTANCE: disclosed is a method of measuring moisture content of a substance moved through a conveyor with extended metal rollers, where a detecting element is placed with or without contact with the conveyor belt and the value of its information-bearing parameter is determined, from which the value of moisture content is determined. The detecting element used is a piece of a long line, at least one of two conductors of which is one or more neighbouring extended metal rollers of the conveyor. Electromagnetic vibrations are excited on this piece of long line. The information-bearing parameter used is one of its resonance frequencies of electromagnetic vibrations, particularly the main resonance frequency.

EFFECT: high accuracy of measuring moisture content of a controlled substance.
