摘要： A device for measuring and remotely checking external dimensions of an external lateral face of a part of a work piece. The device comprises measuring means for measuring the length of the part and including a set of two ultrasonic transducers arranged to transmit and receive ultrasound pulses, a movable support for supporting the transducers, abutting means, first rotation means for rotating the supporting means about an axis parallel to the longitudinal axis of the workpiece, and second rotation means for rotating the supporting means between an initial position where the two transducers are substantially directed along a line perpendicular to the longitudinal axis of the workpiece and two predetermined angular positions symmetrical with respect to the initial position, and means for rectilinearly displacing the movable support for bringing the movable support into and out abutting contact with the lateral face to be measured.

摘要： An ultrasonic transducer carried by rod means of dimensions such that it may be inserted in the assembly between an end piece and the caps of the element, and a crossed movement moving mechanism for bringing the transducer above the different elements. It further comprises a mechanism for moving rod elements in the longitudinal direction of the fuel elements. The transducer is set up on rod elements with at least one degree of freedom about a shaft transversal to the fuel elements so as to be able to be applied flat against the end face of a cap.
