Abstract (en)
[origin: WO0111375A1] The invention relates to a method and a device for detecting errors in a system for measuring the rotation of a shaft (12). For that purpose, said device (60) comprises measuring means (22) for recording a first signal and a second phase shift signal (24, 26), and operating means (62) comprising a comparator for comparing instantaneous values of the first and second signals (24, 26) on the basis of a predetermined geometrical relation. When the operation is correct, the sum of the squares of said two signals is constant. Alternatively, authorised combinations of signal values can be stored in a table.
