<p>An apparatus for measuring the force applied by an elastically flexible element undergoing a pre-set elastic deformation, includes a horizontal lever, unbalanced by a known and constant torque, the axis of rotation of the lever defined by a fulcrum. The lever is coupled to a slider, movable in a horizontal direction, and includes a rest surface that touches the slider, while a portion of the flexible element is fixed to a base. The slider is urged to displace in a horizontal direction and, in the course of the displacement, position sensors detect the height of the rest surface - indicative of the height of the slider and of the deformation of the flexible element - and the distance of the contact zone between slider and rest surface from the axis of rotation of the lever. The amount of said distance, when the height of the rest surface indicates the pre-set elastic deformation of the flexible element and the unbalance torque is balanced, is utilized for calculating the force to be measured.</p> |
