Abstract
A device is disclosed for in situ detecting of axial motion of a generally cylindrical member in which both ends of the member are unavailable for the installation of a prewound coil. The device comprises a predetermined length of generally flat multiconductor cable. A first connector component is secured to one end of the cable, the first connector component having a plurality of electrical contacts, the number of contacts being at least two greater than the number of conductors of the cable. A second connector component is secured to the other end of the cable, the second connector component having a plurality of electrical contacts, the number of contacts being at least two greater than the number of conductors of the cable. The two connector components are interconnected with the cable surrounding the cylindrical member so that contacts of the first and second connector components interengage to contact together predetermined conductors of the cable to form two generally parallel, independent coils extending around the cylindrical member with the ends of the coils being located on the first and second connector components. A current source is electrically connected to one of the coils for imparting current through the one coil. A display device is electrically connected to the other of the coils for receiving voltages induced in the other coil. The induced voltages are proportional to the velocity of axial movement of the cylindrical member through the coils.
