Abstract:
1. A measurement system for measuring a degree of stratification of moisture in a moving flat sheet product, said system comprising: one or more sources that provide radiation incident to first and second sides of said moving flat sheet product at a measurement station adjacent said moving flat sheet product; a first reflection gauge and a second reflection gauge that are located on said first and second sides of said moving flat sheet product at said measurement station and that respond to said radiation in the infrared range to provide first and second reflection output signals, respectively; a first transmission gauge and a second transmission gauge that are located on said first and second sides of said moving flat sheet product at said measurement station and that provide first and second transmissive output signals, respectively; and a controller that processes said first and second reflection output signals and said first and second transmissive output signals to provide a measurement of a degree of stratification of moisture within said moving flat sheet product, and wherein said measurement comprises a moisture value of a location within a depth of said moving flat sheet product.
