ABSTRACT:
An apparatus and a method for measuring the force (GL) applied by an elastically flexible element (5;71,71′) undergoing a pre-set elastic deformation, more specifically an element that carries a slider (3) and includes a thrust device that applies a force to the flexible element. The thrust device includes, for instance, a pneumatic nozzle (27;57,57′;28) for applying a force (R) to an intermediate portion (4) of the thin plate, at a thrust section (K). A position sensor (30;80) detects the height (z) of the slider—indicative of the deformation of the flexible element. The value (MF) of the moment of the applied torque when the height (ZF) of the slider indicates the pre-set elastic deformation of the flexible element, is utilized for calculating the force to be measured according to the formula GL=MF/L where L is the distance separating the slider from the section of weakness.
