<p>A non-contact sensor system is provided that comprises a first sensor element and a rotary member disposed proximate the first sensor element without physically contacting the first sensor element. The rotary member may be configured to be rotated about an axis Y by a shaft configured to pass through the rotary member along the axis Y at a value X or the axial movement or displacement of the shaft. The non-contact sensor system further comprises a second sensor element disposed on the rotary member proximate the first sensor element without physically contacting the first sensor element, and the first sensor element and the second sensor element may be operatively coupled to facilitate sensing the value X. The value X may be determined from a value Z which is associated with the rotation of the rotating member. For example the displacement of a shaft carrying helical grooves or a screw thread may be detected by the rotary motion of an interfering member through which it passes.</p> |
