Zusammenfassung:The invention relates to a load cell with a spring body formed rotationally symmetrically about a center axis, and a plurality of strain gauges arranged on a lower side of the membrane for detecting a stretching and/or compressive deformation of the spring body, wherein the strain gauges are electrically connected to a Wheatstone bridge or as a part thereof, with at least one first strain gauge. The spring body has an outer support ring, an upwardly projecting inner force introduction element, and an annular deformation section that is formed as an annular membrane and with which the support ring and the force introduction element are fixedly connected to one another. The mean thickness of the annular membrane in the region of the first strain gauge or gauges is larger than the mean thickness in the region of a second strain gauge or gauges.
