Pressductor PillowBlock Load cells - horizontal force measurement


Pressductor PillowBlock horizontal load cells are ideal in applications characterized by low tension levels, heavy rolls and high operating speeds - a scenario often encounted in the paper industry.

The PillowBlock comes in three versions: The standard version, PFTL 101A/B, is often used for accurate measurement in the paper industry, for instance paper machines, calenders, coaters and winders.

For web tension measurement in dryer sections in paper machines, the mill duty version, PFTL 101AE/BE, is recomended. This version has a fixed connection cable and a degree of protection of IP 66, which provides accurate and reliable measurement with long service life.

The acid resistant version, PFTL 101AER/BER, is designed for the wet end of the paper machines and has a degree of protection of IP 66/67.

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. (Move your mouse over the illustration to see these changes.) 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.
