Abstract
A measurement instrument in the form of a plug gage comprises a tubular body within which there is centered an axially movable rod, one end of which is intended to transmit the axial movements of said rod to a transducer system connected to the tubular body, while the other end thereof bears a conical part coaxial with said rod, with the lateral surfaces of the conical part resting against radially movable feeler balls, each of which is housed in a guide channel transverse to the longitudinal axis of the tubular body. The plug gage is characterized in that the tubular body bears over at least a portion of its length a coaxial centering sleeve which is removable and interchangeable, this sleeve being provided with transverse openings intended to permit the passage of the balls.
