ABSTRACT:
A roller shell is rotatably mounted on a non-rotatable axle having an axial bore and is engageable with moving strip. A detector is non-rotatably mounted on said axle and comprises a magnet which produces a magnetic field and a sensing coil arranged to generate voltage signals in response to magnetic flux changes in said magnetic field. An annular rotor is disposed between said axle and said shell and non-rotatably connected to said shell and movable in said magnetic field to produce a predetermined magnetic flux change in said magnetic field in response to a predetermined angular movement of said shell. A lead is connected to said detector and extends in said axial bore and is arranged to transmit said voltage signals. In a hot strip mill, said axle is carried by pivoted arms tending to urge said shell against the underside of a strip contacting the top of said shell so as to support and tension said strip.
