An industrial roll includes: a substantially cylindrical core having an outer surface; a polymeric cover circumferentially overlying the core outer surface; and a sensing system. The sensing system includes: a first signal carrying member serially connecting a first set of sensors; a second signal carrying member serially connecting a second set of sensors; and a signal processing unit operatively associated with the first and second signal carrying members and configured to selectively monitor the signals provided by the first and second set of sensors.

Industrial roll with multiple sensor arrays

An industrial roll includes: a substantially cylindrical core having an outer surface; a polymeric cover circumferentially overlying the core outer surface; and a sensing system. The sensing system comprises: a plurality of sensors embedded in the cover, the sensors configured to detect an operating parameter of the roll and provide signals representative of the operating parameter, wherein one of the plurality of sensors is a tracking sensor and the remaining sensors are non-tracking sensors; and a processor operatively associated with the sensors that processes signals provided by the sensors. The sensors are arranged at a substantially equal radial distance from the core outer surface, such that they define a circle when viewed from an end of the roll. Each of the non-tracking sensors is further arranged at a substantially equal first angular distance from its immediate non-tracking sensor neighbors, two endmost non-tracking sensors defining an angular gap. The tracking sensor is disposed in the angular gap, such that a second angular distance defined by the tracking sensor and either of the endmost sensors differs from the first angular distance. In this configuration, the sensing system can identify from which sensor signals are generated without a trigger signal generator or accelerometer.

Industrial roll with sensors arranged to self-identify angular location

An industrial roll includes: a substantially cylindrical core having an outer surface and an internal lumen; a polymeric cover circumferentially overlying the core outer surface; and a sensing system. The sensing system includes: a plurality of sensors at least partially embedded in the cover, the sensors configured to sense an operating parameter of the roll and provide signals related to the operating parameter; and a processor operatively associated with the sensors that processes signals provided by the sensors. Each of the plurality of sensors includes: a first electrode overlying the top surface of a substrate and a second electrode underlying the bottom surface of the substrate, wherein the first electrode overlies the top surface of the substrate and the second electrode underlies only a portion of the bottom surface of the substrate, thereby forming a gap adjacent the bottom surface and a side surface of the substrate; a first sheet of conductive material attached to the first electrode and the side surface of the substrate and extended in a first direction away from the bottom surface of the substrate; and a second sheet of conductive material attached to the second electrode and extended in a second direction away from the bottom surface of the substrate, the second surface being opposite the first direction.
