Abstract

A force transducer for measuring compression and/or tension forces includes a rod-shaped deformation body and at least four strain transducers applied on the deformation body and configured for measuring a longitudinal strain and a transverse strain of the deformation body. Front and rear elongate recesses are provided on the front and rear sides of the deformation body at an intersection point between a central longitudinal axis and a central transverse axis of the deformation body. Left and right upper indentations and left and right lower indentations are provided on the deformation body respectively at the four quadrants bounded by the axes. An angle between the central transverse axis and a shortest connecting line between the front elongate recess and the left upper indentation is at least 17° and at most 29°.
