Abstract

A measuring arrangement for form measurement of cylinders, comprises a measuring arm insertable into a cylinder space, a measuring sensor which is guided by the measuring arm, movable translatorily in the direction of a longitudinal axis of the measuring arm and driveable independently of the measuring arm in a circumferential direction, a sensing pin which is displaceable radially and along an axis of the measuring sensor and arranged for sensing a geometry of walls of cylinders, a driving arm which is movable translatorily and rotatably and having an end, the measuring arm being formed as a thin sensing body which is in operative connection with the end of the driving arm, formed bending-resistant, and extends parallel to the driving arm, the sensing body having an end which is spaced from the driving arm and carries the measuring sensor, and the measuring sensor being provided with the sensing pin.
