The ABB PFTL 101A – 2.0kN is a high – precision load cell designed for accurate force measurement in industrial applications, especially suitable for tension measurement of rolls in the paper industry and other fields8. It is based on the Pressductor® technology, which utilizes the magnetoelastic effect measurement principle8. When subjected to mechanical force, the transducer generates measurement signals due to changes in the magnetic field8. These signals are high – power, low – impedance AC signals, which are highly resistant to electrical interference and earth faults8. The sensor features a pillow – block design, which can effectively reduce the influence of external interference factors on the measurement accuracy, ensuring high measurement accuracy and stability. In addition, it has a compact structure, is easy to install and maintain, and can work stably in a variety of complex industrial environments.
