  • Patent number: 4716774
    Abstract: A force measuring cell has a force sensor in the form of a bendable support. The base part and the load-receiving element of the force sensor are connected by two elastically bendable link members with pronounced bendable segments. Strain gauge elements in the form of strips are disposed on the bendable segments of one of the link members, to produce an electrical signal corresponding to the force (F) being measured. In order to achieve uniformity of the magnitudes of the stresses on all the bendable segments when under load, the mean material thickness of the bendable segments of the link member, which bendable segments are disposed closest to the base part, is thicker than the mean material thickness of the other bendable segments, corresponding to the larger bending moments which occur at the first-mentioned bendable segments. Thus the same degree of expansion or compression occurs in all the bendable segments and in the strain gauge elements associated with said bendable segments.
