Abstract:
An axial deformation transducer comprising:a first clamping assembly having a first and second spaced apart clamping semicircular collars with flanges extending outward therefrom along the open diameter, a first pushing pillar extending from said first collar in an axial direction toward said second collar, a second pushing pillar extending from said second collar in an axial direction toward said first collar and a first sensing platform extending orthogonal to and between said first and second pillars and at the end of each pillar forming an integral structure;a second clamping assembly having a third and fourth spaced apart clamping semicircular collars with flanges extending outward therefrom along the open diameter, a third pushing pillar extending from said third collar in an axial direction toward said fourth collar, a fourth pushing pillar extending from said fourth collar in an axial direction toward said third collar and a second sensing platform extending orthogonal to and between said third and fourth pillars and at the end of each pillar forming an integral structure;fastening means extending through each of said flanges for securing said first and second clamping assembly together;a first and second strain gage connected to said first sensing platform and a third and fourth strain gage connected to said second sensing platform;circuit means for electrically connecting said first, second, third and fourth strain gages in a bridge for measuring the electrical changes in each gage in response to axial movement of said pushing pillars; andmeans extending through each of said first, second, third and fourth collars for securing said first and second clamping assemblies around a circular cross section of the member to be measured forming an axial deformation transducer.
