Abstract
Digital micrometer having an encoder rotor and an encoder stator. The encoder stator is fixedly secured to the micrometer which the encoded rotor is rotatably mounted in the micrometer but is prevented from moving axially so as to cooperate with the stator. The rotation of the rotor is correlated to the axial movement of a lead screw for the measurement through a thimble so that the measured value is obtained by the cooperation of the rotor with the stator.
