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.

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.

Pressductor® Technology

The first Pressductor transducer was developed in Västerås, Sweden, in the early 1950's and patented in 1954.

ABB's well-known Pressductor® Technology is a measurement principle based on the magnetoelastic effect - the magnetic properties of a material are influenced by the mechanical force applied to it.

When exposed to mechanical force, ABB's Pressductor transducer produces measurement signals as a result of changes in magnetic fields. Because these signals are not contingent upon physical movement or deformation, the load cells combine sensitivity with extraordinary tolerance to overloads and virtually no built-in limit to the number of load cycles.

The ABB Pressductor transducers produces high-power, low-impedance AC signals that are very resistant to electrical interference and earth faults.

ABB's Pressductor transducer stands for unbeatable load cell performance, thanks to its unique combination of accuracy, overload capacity and ability to withstand harsh environments.

 By using this technology you will achieve higher quality and reliability, especially under demanding conditions.
