US 2019/0265016 A1 · STRAIN GAUGE

Abstract

A strain gauge for mounting on a surface. The strain gauge comprises first and second mounting pads arranged for securing to respective first and second portions of the surface. The first and second mounting pads having respective first and second upstanding walls each arranged to extend away from the surface to a bridging portion extending between the first and second upstanding walls. The strain gauge has a strain sensing element secured to one of the first and second upstanding walls.

A strain gauge for mounting on a surface, the strain gauge comprising

a first end for securing to a first potion of the surface,
a second end for securing to a second portion of the surface,
a bridging portion extending between the first and second ends, the bridging portion including a measurement surface, and
a strain sensing element secured to the bridging portion,
wherein the strain gauge extends in a first direction from said first end to said second end,
wherein the strain gauge is configured such that, when said surface is deformed in a direction generally parallel to the first direction, a first portion of the measurement surface undergoes compressive deformation, and a second portion of the measurement surface undergoes tensile deformation, and
wherein the strain sensing element includes
a first sub element arranged to sense deformation of the first portion of the measurement surface, and
a second sub element arranged to sense deformation of the second portion of the measurement surface.
