FIELD: measuring technique; mechanical engineering; automatic control systems.
SUBSTANCE: device can be used for checking force of drawing-up of threaded connection under effect of as static and dynamic loads. Device for checking force of drawing-up of threaded connection has fastening member with axial opening. Rod is disposed along side surface to have space inside axial opening. Device also has aid for measuring linear shifts. One end of rod is fastened in head of fastening member and anchor of measuring aid is fastened at other end of rod for measuring linear shifts of eddy-current detector. The detector itself is mounted onto cap which is fastened onto unloaded threaded part of fastening member. Automatic continuous checking is provided during total period of effect onto tested object as static and dynamic (vibration and shock) loads as well as set of loads.
EFFECT: improved reliability of operation.
