Utility
Inductive movement sensors
17 Feb 20
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.

Utility
Inductive displacement sensors
10 Feb 20
A target for an inductive displacement sensor is provided, including a plurality of conductive patterns distributed along a zone having a dimension Dtot in a direction, the patterns being defined by the overlay of at least a first set of elementary periodic patterns having a period approximately equal to Dtot/N, including N first elementary conductive patterns of a dimension approximately equal to Dtot/2N in the direction, regularly distributed along the zone, and of a second set of elementary periodic patterns having a period approximately equal to Dtot/(N+r), including N+r second elementary patterns of a dimension approximately equal to Dtot/2(N+r) in the direction, regularly distributed along the zone, where N is an integer greater than or equal to 2 and r is a positive integer, different to zero and less than or equal to N−1, wherein first and second elementary conductive patterns overlap at least partially.
