Abstract (en)
[origin: WO0047291A1] Apparatus for detecting the position of an object relative to a plane, comprising at least one energising coil (1) and at least one detecting coil (3, 4), the coils being arranged so that as an object (10) moves relative thereto it affects the detected signal; and phase sensing means for detecting signal variation and indicating the presence or position of the object. The apparatus is arranged so that a detectable phase reversal occurs as the object crosses the plane.
