Product Introduction
The ABB 20KN 3BSE023409R20 is a Pressductor PillowBlock load cell designed for accurate force measurement in industrial strip-tension systems. Unlike conventional strain-gauge load cells, the Pressductor principle uses changes in magnetic properties caused by mechanical stress; the sensor’s primary and secondary windings generate an electrical signal proportional to the applied force.
The ABB 20KN 3BSE023409R20 is used where the load cell forms part of a mechanical measuring-roll arrangement, with the resulting signal processed by dedicated ABB tension electronics. ABB has documented PFCL 201C installations in rolling, annealing, pickling, tension-leveling, and skin-pass processing lines, including furnace sections where stable strip-tension measurement is important.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
In a strip-processing line, a tension sensor failure is not simply an instrumentation problem. Incorrect force measurement can affect strip tracking, roll loading, tension control, product quality, and ultimately the ability to maintain the process within its operating window. The is part of the mechanical measurement chain, so the installation geometry is just as important as the electrical specification.
Typical Applications
- Steel rolling mills — strip-tension measurement around rolling and finishing sections.
- Continuous annealing and pickling lines — ABB documentation specifically shows PFCL 201C used in demanding processing-line environments.
- Tension-leveling and skin-pass mills — monitoring force around measuring rolls and tension-control sections.
- High-temperature furnace sections — where mechanical arrangement and stable tension measurement are critical. ABB documents PFCL/PFTL PillowBlock load cells in furnace-section applications.
Technical Pitfalls to Avoid
- Do not confuse with PFTL201C. The two families are both Pressductor PillowBlock load cells, but their mechanical measuring arrangements differ. ABB documentation lists both families in 20 kN and 50 kN configurations. Verify the installed mechanical arrangement before substitution.
- Check the load direction, not just the capacity. A 20 kN rating by itself does not establish whether a particular installation is suitable. Measuring-roll geometry, bearing arrangement, force direction, roll weight, strip tension, and transverse forces all contribute to the actual load seen by the sensor.
- Do not treat it as a complete tension transmitter. The is the sensing element. The associated tension electronics provide the required excitation, signal processing, display, and control-system interface. ABB’s PFEA family is specifically designed for tension-electronics applications and supports configurations using multiple load cells.
- Mechanical alignment matters. The load-cell mounting surfaces and measuring-roll arrangement need to be checked carefully. ABB installation material emphasizes correct mounting geometry and warns that forces introduced through cabling or incorrect installation can influence the measured force.
- Do not substitute a generic strain-gauge cell solely because it has a 20 kN rating. The Pressductor sensing principle, mechanical dimensions, excitation requirements, and associated ABB electronics form an integrated measurement system. A generic 20 kN load cell is not automatically electrically or mechanically interchangeable.

Procurement note: For a replacement order, specify the complete 20KN / 3BSE023409R20 designation and compare the installed sensor’s mechanical drawing, mounting arrangement, rated capacity, cable configuration, and associated PFEA/tension-electronics setup. For this type of component, a matching part number is necessary, but mechanical compatibility is equally important.
