Abstract
The present invention relates to the free point tool and a sensor for assembly for use in the free point tool. The sensor assembly comprises a first housing having an axis in a transmitter coil mounted thereon as well as at least one receiver coil. The axis of each coil is substantially parallel to the axis of the first housing. The second housing is movably attached to the first housing such that it can move along the axis of the first housing and also rotate about the axis of the first housing. The second housing carries the sensor plate which is located operatively adjacent to the receiving coils. Movement of the plate relative to the receiving coils changes the output of the receiving coils.
