Our customer has a feed roller system. They require to monitor and maintain a constant pressure between the two ends of the bottom roller to maintain a straight feed.
The bearings at each end of the bottom roller are mounted on a separate load cell. The output from each load cell is connected directly into a Tiger 320 Series controller.
The controller displays the difference in pressure between load cell 1 and load cell 2. If load cell 1 is lower than load cell 2, the controller displays the negative difference. If load cell 1 is higher than load cell 2, the controller displays the positive difference. If both pressures are equal, the controller displays 0.
