  • Patent number: 5012680
    Abstract: A stress gauge force sensing device is provided comprising a circular ring connected to a hub by a sector. The hub bears on a shaft integral with a supporting structure. The end of the tie to which the load is applied passes round the ring then is connected to the supporting strand of this tie by a fastener. The sector, which supports the stress gauge system, is placed, in the axis of the force, along the radius of the ring situated on the same side as the load with respect to the axis of the ring. The stress sensor forms at the same time a coupling member for the tie supporting the load and thus reduces the length which interpositioning of the sensing device occupies in the load line.
