| 摘要 |
The invention relates to an inductive movement sensor comprising: a transducer (201) comprising a primary winding suitable for producing a magnetic excitation, and a secondary winding comprising at least one turn, suitable for applying an electromotive force across the terminals thereof in the presence of said excitation; and a target (203) comprising at least one conductive pattern, said target (203) being suitable for moving parallel to the transducer (201) such as to cause variations in the surface of a portion of the pattern located opposite said at least one turn, thereby causing variations in the amplitude of the electromotive force induced in the secondary winding, in which the target-transducer distance (d) is between 0.8 and 1.5 times the optimum target-transducer distance in terms of linearity, or the distance for which the linearity error (EL) of the curve representative of said variation in amplitude as a function of said surface variation is minimal. |
