FIELD: in-process check and measurement technology.
SUBSTANCE: proposed device for in-process checking and servicing process channels of nuclear reactors has housing that mounts drive, probe, and coupling line. The latter is made in the form of multiple-section flexible coupling. Electric coupling circuit is disposed inside flexible coupling. One end of coupling line is attached to probe shank. Other end of coupling line is inserted in housing and passed through guide roller of drive. Each section of multiple-section flexible coupling is joined with next section by means of axle. The latter is perpendicular to longitudinal axis of multiple-section flexible coupling. Each section of multiple-section coupling is free to turn relative to next section in plane perpendicular to plane of turn of preceding section.
EFFECT: ability of eliminating disadvantages of multiple-section flexible coupling while retaining its advantages.
