Thayer Scale Mat Weigher Designed for OSB

Thayer Scale’s Mat Weigher has been specifically designed to accurately weigh a continuous, stream of material such as polystyrene ceiling tiles, pre-pressed OSB/MDF or gypsum wall board mat stream. The weighing systems provides an accurate and repeatable load measurement that can be used to make intelligent forming system adjustments allowing the operator to monitor and/or control the density of the material flowing to the forming machines, as well as the weight of the formed mat, improving overall board quality and reducing the amount of off-spec board produced.

The Mat Weigher consists of a Force Measurement Suspension System (FMSS) interposed between a live, multi-idler weigh bridge . The FMSS is a moment-sensitive reaction device that functions as a force vector filter; allowing the sum of vertically directed load forces to produce a change in measurement output while blocking all of the extraneous horizontal force vectors ( friction, torsional forces, etc.) that produce measurement non-repeatability and calibration drift. The FMSS also provides a means to mass counter-balance all dead load (weight of weigh bridge, idlers, etc.) and provide overload protection so that load cell selection can be made based on the NET, rather than GROSS requirements of the application. This unique design provides a low cost of ownership as the weight transducer can be inspected and/or replaced without first having to remove the weigh bridge. The Mat Weigher ensures high accuracy, repeatability and reliability, quick calibration and easy installation even existing lines.
