Abstract: The invention concerns a method and a device for measuring a torque. The measuring method is characterized in that it consists in fixing on said part (1) at least two identical sensors (2) for measuring deformation, directly mounted between two separate anchoring points (A, B) and positioned on two curves (a) of the part (1) sloping at an angle a relative to the part (1) axis. Said sensors are designed to deliver electric signals based on modifications in distance between their respective anchoring points generated by said deformation.

Abstract: The invention concerns a tensile testing sensor mounted on a mechanical member wherein forces to be measures develop comprising a bendable metal blade (1, 22) provided with measuring gauges (2, 23) implanted and positioned on the blade. Said blade (1, 22) is sensitive to mechanical tensile and compressive deformations sustained and transmitted via two bearing parts (4, 5, 20) coupled to the mechanical member wherein the forces develop. The sensor is equipped with a mechanically locking flange (31) placed during calibration between the bearing parts (4, 5, 20) and the sensor blade.
