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.


Surface Sensor

Surface Sensor

Ideal for measuring bulk solids and sheet-like material, surface sensors can successfully detect moisture levels of between 1 to 60%. The sensors are capable of measuring an average of up to 10,000 samples per second, enabling manufacturers to meet the high-speed demands of today’s production lines.


Flow Through Sensor

Flow-through sensors are the ideal solution for measuring powder, particles, and compact materials up to 20mm. Using these sensors, manufacturers can determine the amount of moisture in a material ranging between 1 to 15%. Density measurements can also be taken based on kg/m3. Designed to meet the rapid demands of today’s production lines, our flow-through sensors can measure an average of up to 10,000 samples per second.
