ABB PFEA113‑20 3BSE028144R0020 Tension Measuring Electronics Unit

The ABB PFEA113‑20 (3BSE028144R0020) is a high‑precision tension measuring electronics unit for Pressductor load sensors. It receives multi‑channel strain‑signal inputs from tension sensors, converts raw sensor signals into standard analog and digital outputs, delivering accurate web‑tension measurement for paper, film and metal‑strip processing production lines.

This DIN‑rail mount unit integrates local display, function keys and Profibus‑DP communication interface. It supports sum‑difference tension calculation and on‑site parameter setup. It serves as vital aftermarket spare for maintenance, overhaul and retrofitting of web‑handling industrial automation systems.
