Abstract
An industrial roll includes: a substantially cylindrical shell having an outer surface and an internal lumen; a polymeric cover circumferentially overlying the shell outer surface; and a sensing system. The sensing system comprises: a plurality of sensors embedded in the cover, the sensors configured to sense an operating parameter of the roll and provide signals related to the operating parameter, wherein at least some of the sensors include an aperture; and a processor operatively associated with the sensors that processes signals provided by the sensors. In some embodiments the shell and cover include through holes that extend through the sensor apertures.
