The ABB PFTL 101A – 1.0kN is a precision – grade load cell designed for accurate force and weight measurement in various industrial applications, especially suitable for tension measurement of rolls in the paper industry and other fields7. It adopts the magnetoelastic effect measurement principle4. When subjected to mechanical force, the transducer generates measurement signals due to changes in the magnetic field4. These signals are high – power, low – impedance AC signals, which are highly resistant to electrical interference and earth faults4. 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 stability1. In addition, it has a compact structure, is easy to install and maintain, and can work stably in a variety of complex industrial environments2.
