Abstract
A device for monitoring the temperature and tightening of a screw includes a temperature detector positioned near the screw head for measuring the temperature of the screw, a detector of the tightening of the screw, including a sensor member including a first part, positioned on the screw head so as to be rotationally fixed to the screw, and a second part, fixed relative to the first part and arranged to generate a detection state representing a position of the first part relative to the second part, and a first detection unit connected to the sensor member and arranged to determine a degree of tightening of the screw as a function of the detection state of the sensor member.
