The ABB PFEA112-65 is a high-precision tension electronics unit designed for demanding industrial web processing applications. This field-mountable unit processes signals from up to two ABB Pressductor® magneto-elastic load cells (PFTL or PFCL series) and provides real-time tension measurement and control for materials such as paper, film, foil, textiles, and cable .
The -65 designation indicates the IP65 enclosure version — a rugged, wall-mounted housing that provides protection against dust and water jets . Unlike the IP20 DIN-rail variant (PFEA112-20), this version is specifically engineered for direct installation in harsh, dirty, or wet environments such as paper mills, metal processing lines, and outdoor installations .
This module is available with two ordering numbers — 3BSE030369R0065 and 3BSE050091R65 — which represent the same functional unit under different ABB ordering systems.

The PFEA112-65 processes weak magneto-elastic signals from the Pressductor® sensors and performs precision signal conditioning to calculate :
Sum Tension — Total tension measured across both load cells
Difference (Differential) Tension — Difference between the two sides
Individual Sensor Signals — Per-sensor measurement values
| Mode | Description |
|---|---|
| Manual Control | Direct operator-set output for simple applications |
| Automatic PID Control | Closed-loop regulation of tension to maintain setpoint |
| Constant Tension | Maintains steady tension regardless of speed variation |
| Taper Tension | Reduces tension with increasing roll diameter (winding applications) |
Profibus-DP Fieldbus: Transmits tension values, status, and diagnostic information to upper-level PLC/DCS systems
Analog Outputs: Directly drives drives, brakes, or PLC analog input channels for closed-loop control
Local Display: 2×16 character LCD provides real-time tension readings in user-selectable units (N, kN, kg, lbs)
