Abstract
A device for measuring the moisture content of a module of material, including: (a) a source of microwave radiation for producing a microwave radiation source beam, at least a portion of the source being located on one side of the module; (b) at least one microwave antenna located on an opposing side of the module for receiving an exit beam and for producing an antenna signal, the exit beam being the source beam after a transition from the source to the antenna; (c) an attenuation unit for receiving a first portion of the antenna signal and for measuring an attenuation of the antenna signal; (d) a phase shift determiner for receiving a portion of the source beam and a second portion of the antenna signal and for determining a phase shift of the source beam and the antenna signal, the phase shift determiner including: (i) a raw phase shift measurer for determining a raw phase shift of the source beam and the antenna signal; and (ii) a phase region determiner for determining a phase region of the raw phase shift from the attenuation and producing a corrected phase shift; and (e) a moisture determiner for determining a moisture content of the module from the corrected phase shift and the attenuation.
