The present invention relates to a method and a device for measuring stress forces in refiners having refining discs that define a refining gap between them for refining material between bars (3) arranged on the refining discs. In accordance with the invention the measurement takes place over a measuring surface (7) constituting a part of a refining disc and said measuring surface comprises at least partsd of more than one bar (6). The measuring surfae is resliently mounted in the surface of the refining disc and the measurement takes place through the measuring surface being resliently mounted in a direction parallel to the surface of the refining disc and, in the event of a stress force, being movable in said direction in relation to two rigidly mounted force sensors (10, 11) with which the measuring surface is connected and whic are arranged to produce oppositely directed deflection when the measuring surface is influenced by said stress forces, and in that said stress forces are calculated on the basis of the difference between the deflections measured for respective force sensors on each occasion.
L'invention concerne un procédé et un dispositif de mesure de forces de pression dans des raffineurs contenant des disques de raffinage définissant entre eux un espace de raffinage permettant de raffiner de la matière entre des barreaux (3) disposés sur les disques de raffinage. Selon l'invention, la mesure a lieu sur une surface de mesure (7) constituant une partie d'un disque de raffinage, cette surface comprenant au moins des parties de plus d'un barreau (6). La surface de mesure est montée résiliente sur la surface du disque de raffinage et la mesure est réalisée par l'intermédiaire de cette surface, montée résiliente dans une direction parallèle à la surface du disque de raffinage et, qui soumise à force de pression, peut être déplacée dans cette direction par rapport à deux capteurs de force (10, 11), montés de façon rigide, auxquels la surface de mesure est connectée, et qui sont disposés de façon à produire des déflexions de directions opposées lorsque la surface de mesure est soumise à des forces de pression, ces forces étant calculées en fonction de la différence entre les déflexions mesurées aux capteurs de force respectifs à chaque occasion.
