ABSTRACT:
A force sensing device comprises a parallelepipedic block, the height of which is larger than its width, and which is provided with an opening in the direction of its width so as to form a parallelogram made deformable by the presence of thinner zones in the direction of its height; flexural deformation sensitive elements are fixed to a substantially horizontal section of the block opposite two of the thinner zones which are of a higher flexibility than the other thinner zones. This allows significantly easier manufacturing of low costs while combining high accuracy of measurement and low sensitivity to eccentric loads.
