Abstract

An apparatus for measuring mechanical forces and force actions by means of body, a restoring element and a movable mass, with elements for limiting the deflections of the movable mass. The movable mass is deflected against the resistance of the restoring element under the influence of a mechanical force which, with the aid of sensors, is converted into electrical signals. The elements for limiting deflection include at least two parallel tongues fixed respectively to the restoring element and to the movable mass, and a bridge element fixed at right angles to one of the tongues, at least partly overlapping the other of the tongues.
