Abstract
The device for measuring the longitudinal tension in a strip leaving a rolling mill or stand comprises a measuring roll over which the strip bearingly runs, said roll consisting of at least one roll mounted on active radial magnetic bearings acting as load sensors and supplying a signal based upon the tensile stress in the strip bearing on said measuring roll, and means for measuring the current flowing in the windings of the magnetic bearings, as well as means for detecting the radial position of the rolls supported by said bearings and means for measuring the air gap of the magnetic bearings and keeping said air gap substantially constant.
