Abstract: An inductive detector is provided for measuring the relative position of bodies along a measurement path comprising: an inductive target arranged along the measurement path; a laminar antenna arranged facing a portion of the target; an electronics circuit arranged along the measurement path; wherein, the inductance of at least one winding in the antenna varies continuously in proportion to the relative position of target and antenna.

Abstract: An inductive detector for measuring the position of a first body relative to a second body along a measurement path comprises: a first body which comprises a substantially planar surface and a passive electromagnetic target; a second body which comprises a substantially planar surface facing the planar surface of the first body and an arrangement of laminar windings; said first and second body being configured such that the electromagnetic influence of the first body on the second body varies according to the position of the first body relative to the second body along the measurement path; wherein said passive electro-magnetic target comprises a first portion incorporating said planar surface and a second portion with a lower thickness than said first portion; whereby the second portion incorporates an insulating aperture.

Abstract: An inductive position detector with a first and second body, at least one of said bodies being displaceable relative to the other along a measurement path wherein said first body comprises one or more antenna windings forming a first arrangement of windings and said second body comprises a passive resonant circuit incorporating one or more target windings in series with a capacitor; said circuit covering at least in part said first arrangement; characterized in that said first body comprises an additional winding arrangement disposed along at least part of said measurement path; said additional winding arrangement being spaced from said first arrangement of windings; and said second body comprises an additional winding arrangement covering at least in part said additional winding arrangement of said first body.
