  • Patent number: 4058005
    Abstract: Strain measurement apparatus comprises a rigid support arranged to be secured against the surface of a structure. One or more resiliently deformable carrier elements provided with strain gauges mounted in said support are urged against the surface by the securing of the support to engage the surface at regions spaced from the region of securing of the support and thereby the strains at said regions of engagement are translated directly into deformation of the carrier element or elements to produce measurement signals from the strain gauges. The engagement pressure is transmitted to the elements through resilient means that limit its magnitude while allowing the apparatus to be firmly secured to the surface.
