This means the user only has to follow the step-by-step instructions in order to set up the controller and to obtain correct roll force measurement.More tension controllers:PFCL201C-20KN、PFCL201C-10KN、PFTL101B-20KN
Application program:
ABB has many years of experience in installing load cells on all types of rolling mills.
In order to obtain the best measurement results, there are some basic rules that must be followed during the installation of load cells:
The entire force must pass through the load cell.
The force must be measured as close as possible to the source of the force (roll gap).
The load cell must be protected from large bending, lateral and torsional forces to the greatest extent possible.
Under the mill screw
For installation under the grinding screw, the load cell can be combined with the thrust bearing and pressure plate into a package attached to the grinding screw. The result of this arrangement is good force distribution, simple, inexpensive installation and easy maintenance. In addition, no surface needs to be machined on the roll frame. However, this arrangement does take up space in the scrolling window.
Under the lower back-up roll bearing
The lower part of the roll frame must have a plane large enough to allow the load cell to be installed under the lower support roll bearing. The advantage of this arrangement is that no special attention is required to the load cell during roll change.

Ring load cell between mill nut and mill support
This version makes measurements possible, even when there is insufficient space under the grinding rod and lower support roller bearings. This arrangement also has the advantage that no special attention is required to the load cell during roll change, and it is well protected.
