ABSTRACT:
A piezo-controlled dynamic probe or feeler head for measuring installations and measuring machine, which is in an operative connection with a measurement evaluating or plotting unit and, selectively with a measuring machine control. The probe is constructed from two mutually independently operating measuring signal generating installations, which are equipped with mutually separate or independent circuits and which act in such a manner on the measuring evaluating or plotting unit and, selectively, on the measuring machine control, that upon the generation of a signal from the first measuring signal generating installation, stored data regarding the position of the probe can be recognized as being valid only at the presence of a confirmation or acknowledging signal from the second measuring signal generating installation.
