Sensor for measuring a tightening force applied on a screw-assembly member

A sensor for measuring a tightening force applied to a screw-assembly member, the sensor comprising:

• a ring having at least two faces axially opposite one another and a planar surface oriented perpendicular to the two opposite faces;
• an electronic device comprising a longitudinal support strip having two opposite ends, the support strip being installed on the planar surface;
• the electronic device comprising three circuits mounted on the longitudinal support strip, the three circuits comprising:
• a first circuit configured to generate a signal representative of a tightening force applied in a tightening direction to one of the two opposite faces;
• a second circuit configured to generate a signal representative of the distance of the applied force with respect to a center of the ring in a first direction perpendicular to the tightening direction;
• and
• a third circuit configured to generate another signal representative of the distance of the applied force with respect to the center of the ring in a second direction perpendicular to the tightening direction.
