Load cell with an external interface and weighing foot with a load cell

A weighing foot having a load cell, the load cell comprising

• a spring body comprising an outer support ring, an inner force introduction element, and an annular deformation section, wherein the support ring and the force introduction element are fixedly connected to one another with the annular deformation section, wherein the inner force introduction element comprises a force introduction pipe, and wherein the force introduction pipe comprises an outer wall defining an interior of the force introduction pipe;
• a measuring transducer configured for generating an output signal corresponding to a weight acting on the force introduction element;
• and
• an external interface electrically connected to the measuring transducer and configured to output the output signal generated by the measuring transducer to a device external to the load cell;
• wherein at least one of an electrical energy store for the measuring transducer, the external interface, or an evaluation unit of the measuring transducer is arranged within the interior of the force introduction pipe.
