ABSTRACT:
The deforming body of a force measuring device or load cell is provided with radial stems (3) equipped with foil strain gages (7) and integrally connected to a hollow cylindrical outer ring (1) and to a central hub (2). The outer ring (1) and the central hub (2) extend axially on both sides of a central plane (5) at least as far as three times the largest thickness of the radial stems (3). A force introducing flange (13) is arranged on the outside of the outer ring (1) and lies in the radial central plane (5) of the radial stems (3). Each stem (3) is thicker at its ends near the hub and ring so that the thinnest stem portion is located approximately intermediate the stem ends for providing a linear characteristic for the load cell which is substantially non-sensitive to any loads other than loads applied perpendicularly to the central radial plane.
