Product Overview

• Part No: PFEA113-20, alternative code 3BSE050092R20
• Brand: ABB

• Category: Tension Electronics / Tension Amplifier UnitPFEA113-20 is a professional high-precision tension measuring unit based on Pressductor technology. It receives measurement signals from load cells, processes tension data, and provides standardized analog outputs and digital communication data for the main controller. The unit monitors web tension continuously during production, stabilizes tension of films, paper, textiles and metal strips, effectively avoiding material stretching, breakage and wrinkling. It serves as the core signal processing device of the complete web tension control system.
