  • Micrometer system and process of use therefor
    Patent number: 6286227
    Abstract: A micrometer system includes a motorized drive for repeatedly advancing and retracting the micrometer barrel, and a touch sensor for sensing when the barrel tip has just touched the target surface. The drive is preferably mounted on the micrometer body. By performing a measurement repeatedly, a series of readings can be obtained which cumulatively increases measurement accuracy, especially when contact must be made to a compliant surface.
