Overview

Essential details：PFBL141B-75KN ABB Roll Force load cells

Product Description

The Millmate Roll Force load cells act as integral parts of the mill stand. The rocksolid Pressductor^® load cell design in combination with the intelligent, reliable communication functions are crucial keys to true roll force measurement.

Due to its low impedance and high output signal power the Millmate Roll Force load cells has an extremely low sensitivity to insulation defects and maintains its measuring accuracy down to a 10Ωk insulation level.
The load cell output signal is calibrated for full interchangeability between load cells of the same type and size. The various types and the wide load range cover practically all conceivable roll force measurement applications

PFBL141B-75KN ABB Roll Force load cells

ABB has many years of experience of installing load cells in all types of rolling mills.
To achieve the best possible measurement results, certain basic rules must be observed during the installation of the load cell:
The entire force must pass through the load cell.
The force must be measured as close to the source of the force (the roll gap) as possible.
The load cells must be protected to the greatest possible extent from large bending, lateral and torsional forces.

Under the mill screw
For installation under the mill screw, the load cell can be combined with thrust bearings and pressure plates into a package attached to the mill screw. This arrangement results in good force distribution, simple, inexpensive installation and easy servicing. In addition, there is no need to machine any surfaces on the roll stand. However, this arrangement does take up space in the roll window.

Under the lower back-up roll bearing
There must be a sufficiently large flat surface on the lower part of the roll stand to allow the installation of the load cell under the lower back-up roll bearing. This arrangement has the advantage that there is no need to pay particular attention to the load cell during roll change.

Annular load cell between the mill nut and the mill stand
This version makes measurement possible even if the space under the mill screw and under the lower back-up roll bearing is insufficient. This arrangement also has the advantage that there is no need to pay particular attention to the load cell during roll changing, and it is well protected.
