Title: Omnidirectional capacitive probe for gauge of having a sensing tip formed as a substantially complete sphere

A non-contact, omni-directional capacitive probe for use in dimensional gauging includes an electrically conductive spherical sensing tip that forms a capacitor with a workpiece, the capacitance of the capacitor being indicative of the distance between the spherical sensing tip and the workpiece.
