TORQUE DETERMINATION SYSTEM

A system for determining a torque includes a test body having two bushings, an encoder having two multipolar tracks with a polar width Lpi and Lpe respectively, a sensor having a first (20) - respectively a second (21) - pattern of sensitive elements disposed at a reading distance ei - respectively ee - from the internal track (7) - respectively from the external track (8), and a device for comparing the signals delivered by the sensor to determine an angle between the bushings which depends on the applied torque, the trackshaving an identical number of pairs of poles which are radially aligned, the reading distances ee and ei between the patterns of sensitive elements and the tracks being such that: :eeLpe=eiLpi.ee
