Roll Force load cells

The Millmate Roll Force load cells act as integral parts of the mill stand. 

The rock solid Pressductor® load cell design in combination with the intelligent, reliable communication functions are crucial keys to true roll force measurement.

Overview

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 10kΩ 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.

Application

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.
