Abstract
A suction roll includes: a cylindrical shell having an internal lumen and a plurality of through holes; a suction box positioned in the lumen of the shell; a suction source operatively connected with the suction box; at least one seal strip attached to the suction box and configured to assist in forming a seal between the suction box and the shell; a sensor attached to the seal strip; and a controller operatively connected with the sensor. The sensor is configured to convey signals to the controller, the signals being processed in the controller to provide data on the seal strip on at least one of temperature, wear, vibration, and pressure.

A suction roll, comprising:
- a cylindrical shell having an internal lumen and a plurality of through holes;
- a suction box positioned in the lumen of the shell;
- a suction source operatively connected with the suction box;
- at least one seal strip attached to the suction box and configured to assist in forming a seal between the suction box and the shell;
- first, second and third sensors attached to the seal strip and mounted on a printed circuit board, wherein the first and third sensors are mounted on one side of the printed circuit board and the second sensor is mounted on an opposite side of the printed circuit board;
- and
- a controller operatively connected with the sensors;
- wherein the sensors are configured to convey signals to the controller, the signals being processed in the controller to provide data on the seal strip on at least one of temperature, wear, vibration, and pressure.
