Abstract
An industrial roll includes: a substantially cylindrical core having an outer surface; a polymeric cover circumferentially overlying the core outer surface, the cover including a base layer circumferentially overlying the core and a topstock layer overlying the base layer; and a sensing system. The sensing system includes: a plurality of piezoelectric sensors embedded in the cover base layer, the sensors configured to sense pressure experienced by the roll and provide signals related to the pressure; and a processor operatively associated with the sensors that processes signals provided by the sensors.
