Abstract:
An inductive movement sensor is provided including: a transducer including a primary winding suitable for producing a magnetic excitation, and a secondary winding including at least one turn, suitable for applying an electromotive force across the terminals thereof in the presence of the excitation; and a target including at least one conductive pattern, the target being suitable for moving parallel to the transducer such as to cause variations in the surface of a portion of the pattern located opposite the 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 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 of the curve representative of the variation in amplitude as a function of the surface variation is minimal.
