Abstract
A device for monitoring clamping of an assembly including at least one part to be clamped, an internally threaded element and an externally threaded element engaged in an internal thread of the internally threaded element. The device includes a driver to rotate one of the elements including the internally threaded element and the externally threaded element to clamp the assembly and a first sensor to measure a screwing torque of the driver, a tool for holding fixed against rotation the other of the elements including the internally threaded element and the externally threaded element, a second sensor to measure a reaction torque of the holding tool, a mechanism for determining a third parameter chosen from a time elapsed from a given time and a screwing angle from a reference position, and a calculation system to determine pre-tension in the externally threaded element.
