Abstract
A force transducer with an electromechanical transducer element for fitting in force plates (i.e. measuring platforms) includes adjacent a first axial end a radial mounting flange with a greater outside diameter than that adjacent the second axial end. This make it possible, after connecting the signal lines, to insert the transducer in a mounting hole of the base plate of the force plate and then fix it by welding, brazing, soldering or cementing. The transducer with its signal lines thus becomes an integral part of the base plate and is sealed completely against outside influences. The recesses of the base plate may be filled with a curable resin, providing further portection against mechanical shocks and corrosion influences while at the same time enhancing the rigidity of the force plate.
