Abstract (en)
[origin: FR2923908A1] The method involves alternately measuring electrical voltages (Vx, Vy) between terminals (3) on a strain gauge's substrate. A relation between the voltages is established based on longitudinal and transversal deformations, where the relation is independent to the temperature. The transversal deformations corresponding to the voltages measured along a transversal direction are established. The longitudinal deformations compensated in temperature are calculated from the relation and the transversal deformations, based on measurement of the voltages along longitudinal and transversal directions. Independent claims are also included for the following: (1) a sensor for measuring longitudinal deformation compensated in temperature of a zone of a structural element (2) a roller bearing comprising a sensor.
