ABSTRACT:
A load-measuring device, comprising a ring to be interposed between two opposed bodies coaxial with the load axis. Circumferentially-spaced projections separate one axial face of the ring from one of the bodies, and similar but angularly-staggered projections separate the other axial face from the other body, so that when the bodies approach under load the ring is distorted to an undulating shape. The distortion may be measured by a set of strain gauges fixed to the axial faces of the ring, and the output of a second set of gauges fixed to the radial faces of the ring may serve to compensate for distortions of the ring caused by things other than axial thrust, e.g. temperature variation. The projections may be fixed to the ring, or fixed to and located by the ring casing so that they bear against the ring in use.
