DEVICE AND METHOD FOR DETERMINING THE MOISTURE CONTENT OF MATERIAL

摘要

A device for measuring the moisture content of a module of material, including: a source (28), for producing a microwave radiation source beam, the source being located on one side of the module (10); at least one microwave antenna (128, 130) located on an opposing side of the module for receiving an exit beam and for producing an antenna signal; an attenuation unit for measuring an attenuation of the antenna signal; a phase shift determiner for determining a phase shift of the source beam and the antenna signal, the phase shift determiner including: a raw phase shift measurer for determining a raw phase shift of the source beam and the antenna signal; and a phase region determiner for determining a phase region of the raw phase shift from the attenuation and producing a corrected phase shift; and a moisture determiner for determining a moisture content of the module from the corrected phase shift and the attenuation.
