Abstract

See full text

A load cell has a longitudinal body including a bending beam axially between a force input element and a force output element, strain gages applied on strainable measuring parts of the bending beam, a hermetically sealed enclosure outside around the strain gages and the strainable measuring parts, and an overload protection arrangement including an overload beam in a recess in the bending beam, a receiving hole partially in the overload beam, and a fitting pin received in the receiving hole so that a defined gap is formed between the fitting pin and an adjacent stop surface in the recess of the bending beam. In further embodiments, the enclosure includes a stiff pipe sleeve and ring elements with flexible membranes connecting the sleeve to the longitudinal body, and a mounting end face of the longitudinal body has centering pins in holes and an O-ring in a groove.
