ABSTRACT:
An electronic radius gauge including a base with an inverted U-shaped configuration having a horizontal top post, a pair of side posts each coupled to opposite ends of the top post and depending therefrom, and a vertically oriented bore centrally formed in the top post. The base adapted to be removably situated on a curvature with an associated radius wherein both side posts rest thereagainst. Also included is a control housing with a probe comprising a rod. The rod is adapted to be slidably insertable through the bore and further abut the curvature. A distance measuring mechanism is situated within the control housing and is adapted to calculate a distance the post has slid up or down with respect to an equilibrium position. A display is situated on a front face of the control housing for depicting a plurality of numbers. Finally, a control mechanism is situated within the control housing and connected to the distance measuring mechanism, the display, and a power source. The control mechanism is adapted to calculate and allow the display to depict the radius of the curvature.
