摘要

Providing a position detector for detecting a relative movement of the first and second members mounted (57) for relative movement along SUMMARY measurement path. One member has a magnetic field generator for generating a magnetic field, one of the members has first and second conductors that is inductively coupled with the other magnetic field generator. Magnetic field generating unit and the second conductor is disposed output signal so as to generate the second receiving circuit and the first whose position varies with relative movement between the two members and the first. On that contains information about the relative position between the two members, also includes information defining the relative orientation of the two members, the signal induced in the receiver circuit, two by suitable processing of the received signal relative orientation of the member can also be determined. In one preferred embodiment of the present invention, defines the direction of the first and second orientation and relative position of the movable member of the two systems, the relative orientation of the two members in a plane containing the two directions future There is operable to be determined. It is also possible to process the signal induced in the receiver circuit, to provide an indication value of the gap 2 between circuits, and provides an indication value of the complete relative orientation of the two members.
