1. Product Positioning

ABB PFCL201C-20KN is a high-strength industrial load cell for web/strip tension measurement.

Unlike conventional strain-gauge load cells, it uses ABB Pressductor electromagnetic force measurement technology, providing high mechanical robustness, excellent overload resistance, and stable measurement performance in harsh industrial environments.

Main positioning:

• Industrial strip tension sensing element
• Vertical force measurement device
• Component of ABB Millmate tension control systems
• Designed for continuous process industries
• Suitable for high-temperature, dusty, corrosive environments

---

2. Core Functions

2.1 Vertical Force Measurement

The PFCL201C measures the vertical force applied through a roll bearing housing.

Typical measurement principle:

Strip tension → Roll force → Bearing housing → Load cell → Electrical signal → Tension controller

It can measure force in both directions, making it suitable for bidirectional tension monitoring.

---

2.2 Strip Tension Control

The sensor provides accurate tension feedback for:

• Steel strip processing lines
• Coil handling systems
• Continuous annealing lines
• Pickling lines
• Galvanizing lines

Accurate tension feedback helps prevent:

• Strip breakage
• Wrinkles
• Uneven coating
• Product quality variations

 

---

2.3 Mechanical Load Monitoring

Besides tension control, it can monitor:

• Roll loading forces
• Mechanical stress conditions
• Process stability

---

3. Design Features

3.1 Pressductor® Technology

The sensor uses ABB’s electromagnetic Pressductor principle:

• No traditional foil strain gauges
• High resistance to shock and overload
• Stable long-term performance
• Less sensitivity to mechanical damage

 

---

3.2 Solid Stainless-Steel Construction

The load cell is machined from a single block of stainless steel.

Advantages:

• High mechanical strength
• Excellent corrosion resistance
• High stiffness
• Low deformation

• High-temperature areas

---

Calibration

Recommended actions:

• Verify zero point stability
• Compare output against reference loads
• Check tension controller calibration

---

Replacement Considerations

When replacing:

• Confirm 20 kN capacity

7. Comprehensive Evaluation

Category	Evaluation
Measurement accuracy	★★★★★
Mechanical durability	★★★★★
Harsh environment capability	★★★★★
Long-term stability	★★★★★
Maintenance requirement	Low
Industrial suitability	Excellent

Overall assessment:

ABB PFCL201C-20KN is a premium industrial tension measurement load cell optimized for demanding continuous-process applications. Its Pressductor technology, stainless-steel construction, and high overload tolerance make it particularly suitable for steel mills and heavy industrial production lines where reliability is more important than low-cost sensing.

It is best considered a critical measurement component in ABB Millmate strip tension control systems rather than a standalone sensor.
