Abstract
The load cell has a central force transmission plate (1) joined by a first tubular section (2) to a deformation ring (3) carrying annular strain-gauge elements (9,11) of different diameter on opposite faces. A second tubular section (12) connects the ring to the foot (14) of the cell. An annular groove (4) between the first tubular section and the ring has a floor with different inner and outer radii (R1,R2). The transition radius (R1) of the radially inner boundary wall (5) is between twice and ten times the radius of the outer wall (6).
