ABSTRACT:
A load sensing device for connection in load indicating apparatus between a pair of spaced members arranged to move apart under applied load tension forces, the load sensing device having a hydraulic load cell and an electronic load cell mechanically mounted in stacked series relationship and being respectively connected with a load indicator, wherein the applied tension load forces of the apparatus are mechanically converted into compression load forces for the actuation of the load cells. Manual selectors are also provided to permit the selective use of one or the other of the load cells as the sensing medium to energize its associated load indicator, and which includes a split ring for selectively by-passing the load forces with respect to the hydraulic load cell when utilizing the electronic load cell.
