Abstract
A caliper sensor of the opposing contact type, wherein are provided target supporting spherical surfaces comprising at least three spherical surfaces disposed on a periphery of a target facing plane of a sliding surface and a plane determined by the tops of each spherical surface and in contact in parallel with a measurement reference plane above the target; and contact spherical surfaces for the reference plane outside the target facting plane of the sliding surface, whose number is equal to or greater than that of the relevant target supporting spherical surfaces and the tops of each spherical surface having a height about equal to the relevant target supporting spherical surfaces, so that contaminants are steered away from the tops of the spherical surfaces and the measurement process is thereby unaffected by the contaminants for a long period of time.
