The ABB PFTL 101A – 1.0kN is a pressductor pillow – block – type weighing sensor and tension sensor designed for accurately measuring the weight and tension of objects1. It adopts a pillow – block design, which can effectively reduce the influence of external interference factors on the measurement accuracy, thus ensuring high measurement accuracy and stability1.

This sensor operates based on the pressductor effect or a similar physical principle3. When an object is placed on the pillow block, the pillow block deforms under pressure. This deformation is converted into an electrical signal by the internal strain gauge and then processed by the processing circuit to output the weight value of the measured object1. It is widely used in various industrial fields such as textile, printing, packaging, cable manufacturing, and metal processing, especially in scenarios where precise control of material tension is required3.
