Abstract
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, an O-ring and centering pins. An end face of the force input or output element is to be connected to a weighing scale part in an aligned, force-transmitting, hermetically-sealed manner, for which the end face has centering holes receiving the centering pins, a circular groove receiving the O-ring, and a threaded hole receiving a connecting bolt. Further embodiments involve an overload protection integrated in the bending beam, or the enclosure including a stiff pipe sleeve and ring elements with flexible membranes connecting the sleeve to the longitudinal body.
