ABB PFCL201CE‑50KN
The ABB PFCL201CE-50KN is a high-performance Pressductor® PillowBlock load cell designed for vertical force measurement and strip tension control. It belongs to ABB’s PFCL201 series and is mainly used in demanding industrial web-processing applications where accurate tension measurement and high mechanical durability are required.
The “50KN” designation indicates a nominal measuring capacity of 50 kN (approximately 11,250 lbf), while the “CE” version represents the mill-duty configuration with a fixed connection cable and protective hose, optimized for harsh industrial environments.
Core Function
The PFCL201CE-50KN measures the vertical force component generated by material tension on a roll system. It converts mechanical load into an electrical measurement signal using ABB’s patented Pressductor® magnetoelastic technology.
Unlike conventional strain-gauge load cells, the Pressductor principle relies on changes in magnetic properties caused by mechanical stress, providing:
- High overload resistance
- Excellent long-term stability
- Low mechanical deformation
- Reliable operation under continuous industrial loads

Design Features
1. Robust Stainless-Steel Construction
The load cell is machined from a single block of stainless steel, giving it excellent resistance against:
- Mechanical shock
- Impact loading
- Dust contamination
- Corrosion in industrial environments
2. Mill-Duty Protection
The PFCL201CE version is designed for applications with severe operating conditions. The fixed cable with protective hose improves protection against:
- Moisture
- Mechanical abrasion
- Chemical exposure
- Continuous production-line stress
3. High Overload Capability
The sensor can tolerate overloads far beyond normal operating conditions, reducing the risk of damage from unexpected tension peaks or mechanical disturbances.
Hardware Composition
The PFCL201CE-50KN mainly consists of:
- Stainless-steel load cell body
- Integrated Pressductor sensing element
- High mechanical stiffness structure
- Magnetic sensing system
- Primary excitation winding
- Secondary measurement winding
- Magnetoelastic signal conversion mechanism
- Temperature compensation components
- Designed to maintain measurement accuracy over temperature variations
- Fixed industrial connection cable
- Protective hose configuration for harsh environments
Typical Applications
The ABB PFCL201CE-50KN is commonly used in:
Metal Processing Lines
- Steel strip processing
- Galvanizing lines
- Pickling lines
- Annealing lines
Paper and Pulp Industry
- Web tension measurement
- Wire and felt tension monitoring
- Wet-end paper machine applications
Industrial Web Handling Systems
- Roll force measurement
- Continuous tension control
- Production process optimization
Maintenance Considerations
For reliable long-term operation:
- Ensure correct mechanical mounting and alignment
- Avoid side loading beyond specified limits
- Inspect cable protection regularly
- Keep mounting surfaces clean and rigid
- Verify calibration periodically in critical tension-control systems
Because the sensor has no traditional mechanical deformation element like a strain-gauge bridge, it generally provides excellent fatigue resistance for continuous-duty applications.
Overall Evaluation
The ABB PFCL201CE-50KN is a rugged industrial force measurement solution combining high accuracy, exceptional overload capability, and long service life. Its Pressductor® technology makes it particularly suitable for demanding strip-processing and web-tension applications where conventional load cells may suffer from fatigue, contamination, or mechanical damage.
