Abstract: An arrangement for the electromechanical measurement of the axial clearance of rotating elements, particularly for the measurement of the axial clearance of shafts in high-speed turbomachinery, in which the extended shaft of a drive motor extends substantially perpendicular to the rotational axis of a rotating element and is thereby arranged in parallel with the measured object. The shaft is provided with an eccentric feeler at an end located proximate the measured object so that, at a movement of the eccentric feeler towards the measured object, a contact signal is generated by a contact resistance responsive to falling below of a resistance threshold value between the electrically insulated eccentric feeler and the measured object as measured by an indicator. Concurrently, the instantaneous indicated value of an absolute angle-measuring encoder is stored, and the drive motor controlled so as to reverse the direction of rotation of the shaft into its zero position.
