One of the most serious issues in paper production is when the material becomes too dry or wet. When this happens, the paper must be discarded, wasting a manufacturer’s time and money. This can be prevented by controlling the moisture within a production space.
Utilizing the high-speed measuring technology of microwave resonance sensors, a paper manufacturer can accurately stay within the ideal moisture range of 4 to 8 percent, thus eliminating the threat of moisture. Sensors can measure the surface as well as the interior of the paper without actually coming into contact with the materials. A moisture sensor also has the capability to measure glue layers applied to paper and the drying of printing inks.
Note: Water features distinct dielectric characteristics compared with other materials like wood, i.e. wood changes its dielectric properties in proportion to its moisture content.
