ABB PFEA112‑65 3BSE050091R65 IP65 Pressductor Tension Measuring Electronics Unit

The ABB PFEA112‑65 (3BSE050091R65) is an IP65 field‑mount tension‑measuring electronics unit for Pressductor magneto‑elastic load‑cells. It supports up to two PFTL/PFCL series tension transducers, computes total, individual and differential web‑tension values and delivers analog output plus Profibus‑DP fieldbus communication for roll‑to‑roll closed‑loop tension‑control systems.

This outdoor‑capable enclosure version features built‑in LCD display and keypad for local calibration and parameter setup. IP65 rating permits direct machine‑side installation without cabinet housing, well‑suited for paper‑machines, film‑lines and metal‑foil processing equipment. Widely used as aftermarket spare‑part for production‑line overhaul, load‑cell‑loop debugging and retrofitting projects.

Core Functions

• Process weak magneto‑elastic sensor signals from two Pressductor load‑cells and calculate total, individual and differential web‑tension values.
• Deliver configurable analog measuring signals to drive drives, brakes or PLC analog‑input channels for closed‑loop tension‑regulation.
• Local LCD and keypad support on‑site calibration, zero‑offset adjustment and parameter configuration without PC‑tool.
• Profibus‑DP bus transmits tension‑value, status and diagnostic information to upper‑level PLC/DCS for remote‑monitoring and centralized‑control.
• IP65 rugged housing allows direct installation on production‑machinery, reducing long‑distance analog‑cable runs and signal‑interference risk.
• Sensor‑break and hardware fault‑detection provides alarm‑status output for equipment‑health‑management of continuous‑run web‑processing‑lines.
