Weinig E Scan Series

EScan is a grading machine for structural wood pieces, according to the standard EN-14081. EScan predicts the strength class of a board moving on a cross conveyor, by computing the dynamic Modulus of Elasticity (MOEdyn,long) and the density ?. A mechanical device hits the board in order to create a vibration, which is measured by a laser interferometer. The density (?)
results from combining the weight and dimension measurements. The bending strength is then predicted via statistical
modelling. This proven and reliable technique provides consistent results for the prediction of the mechanical resistance – the strength class-of a board.
