Plasterboards are stocked in the warehouse after production. As they pull in a minimum moisture from the ambient humidity, the target moisture has been fixed on 0.2% after the dryer. TEWS systems deliver reliable results from an in-line installation in the conveyor belt below to passing boards. Our moisture information is transferred directly to the dryer control software. Thanks to our high-speed technology we are able to make up to 20 measurements in the width of each board which even allows eventual wet spot to be found as well as creating in this way moisture (and density) profiles of the single board. The advantages are apparent in the continuous quality control of the drywalls, the optimization of the drying process to save energy and to identify defects of the dryer and, of course, the reduction of non-conforming boards.
From raw material control, to storage monitoring, TEWS microwave resonance unique patented solutions help you get the most reliable data out of your production. TEWS instruments are industry 4.0 ready, and the data can be automatically shared in your data collection system or with your PLC.
