  • Device for performing micromechanical measurements of the surface of test objects
    Patent number: 4577493
    Abstract: The invention relates to a device for performing micromechanical measurements on the surface layer of a test object. An axially movable carrier pipe is arranged in a housing, and a measuring shaft is provided with an indentor arranged within the carrier pipe. An induction generator and an induction displacement sensor are provided surrounding the measurement shaft. A constantly increasing load is applied to the shaft, and the incremental displacement of the shaft is continually measured by the displacement sensor over a predetermined period. According to an alternative embodiment, a displacement actuation device is disposed within the carrier in order to incrementally displace the shaft, and an electrical load sensor associated with the shaft continually measures the load thereon.
