ABSTRACT:
An improved apparatus and process for sensing a test object by means of a switching sensor which is movable relative to the test object, in which the relative position between the test object and the switching sensor is measured by a measuring instrument. The switching sensor generates a switching signal at the moment of contact with the test object in order to cause the instantaneously prevailing measuring value of the measuring instrument to be retained. Such measuring values commonly are characterized by sensing errors as a function of the sensing speed and/or the material pairing between the switching sensor and the test object. In order to correct for such sensing errors the measuring value present at the moment of contact between the switching sensor and the test object is added with previously determined correction values for correcting errors resulting from the velocity of approach between the test object and the switching sensor and/or for the material pairing between the switching sensor and the test object.
