Abstract
A sensor assembly having a pair of sensors and a pair of sensor targets. Each of the sensors is an eddy current sensor that defines X, Y and Z axes that are orthogonal to one another such that the X-axes are aligned to a movement axis along which a structure is to be moved. The sensor targets are coupled to one another for common movement and are formed of an electrically conductive material that is configured to interact with a respective one of the eddy current sensors to cause the sensors to produce sensor signals that each vary in a distinct manner with movement of the targets parallel to the movement axis. The targets are configured such that their coordinated movement in a direction parallel to the Z-axes as they are moved along the movement axis has no effect on the determined location of the structure. A method is also provided.
