A measurement device is for the measurement of the radius of curvature of curved or arched surfaces. It overcomes the difficulties and inaccuracies encountered with surfaces having bumps or indentations with difference measurements between surfaces of large radius where only a small sensor radial motion occurs, and non-constant sensor movement to radius variation relations. A flexible elastic measurement probe has an associated strain gauge attached to it which determines the deformation of the probe and hence the radius of curvature may be calculated. The probe is a strip of spring steel with attached electrical strain gauges whose output signals are converted into a visual display of the radius of curvature. |
