Disclosed is an apparatus and method for measuring the diametral change in a cylindrical component by monitoring and measuring bending (compression and tension) effected by the diametral change in a plane perpendicular to the diameter of the cylindrical component. The apparatus for effecting the method comprises at least one web, but typically two webs, defining planes perpendicular to the diameter of the cylindrical component and strain measuring elements mounted on the web planes and arranged to sense and measure the compressive and tensile (bending) action of the strain-gauge-mounted webs. |
