SUCTION ROLL WITH SENSORS FOR DETECTING TEMPERATURE AND/OR PRESSURE

摘要

An industrial roll (20) includes: a substantially cylindrical shell (22) having an outer surface and an internal lumen; a polymeric cover (24) circumferentially overlying the shell outer surface; and a sensing system (26). The sensing system includes: a plurality of sensors (30) embedded in the cover (24), the sensors (30) configured to sense an operating parameter of the roll (20); and a signal-carrying member (28) serially connected with and extending between the plurality of sensors (30). The signal-carrying member (28) follows a helical path over the outer surface of the shell (22), wherein the signal-carrying member (28) extends over more than one complete revolution of the shell outer surface (and, preferably, an intermediate segment of the signal-carrying member (28) extends over more than a full revolution of the roll (20) between adjacent sensors (30)).
