Product Overview
The ABB PFCL 201C 3BSE027070R20 is a Pressductor PillowBlock Load Cell used for measuring mechanical force in industrial roll and web-handling equipment. It is installed as part of a roll support arrangement, where forces generated by the process are transferred through the pillow block and detected by the sensing element.
The load cell is suited to applications where web tension, roll loading, or process force needs to be monitored continuously. Typical installations include paper and board machines, film and foil processing lines, printing equipment, coating systems, slitting machines, and winding equipment.
ABB Pressductor technology measures mechanical stress through changes in the magnetic properties of the sensing element. The resulting signal can be processed by the associated measurement electronics and supplied to a PLC, controller, or tension-control system.
For replacement work, the complete PFCL 201C order reference should be checked together with the mechanical roll arrangement, measurement electronics, and existing control-system configuration.

Working Principle
The PFCL 201C uses the Pressductor measuring principle to detect mechanical force. When a force is transferred through the load cell, mechanical stress changes the magnetic characteristics of the sensing element. The associated measurement circuitry detects this change and produces an electrical signal corresponding to the applied force.
In a typical web-processing machine, the load cell is installed at a roll bearing support. Web tension and other process forces act on the roll and are transferred through the bearing structure to the load cell. The resulting measurement signal is then supplied to the connected measurement electronics.
The controller can use this force feedback for tension regulation, roll-load monitoring, process supervision, or alarm functions. In a closed-loop tension system, the measured value can be compared with the required process value and used to adjust a drive, brake, or other actuator.
Correct mechanical installation is important because the load cell should measure the intended process force rather than additional forces caused by misalignment, mechanical binding, or unintended contact.
Role in a Web Tension Control Architecture
The PFCL 201C occupies the force measurement position within a web tension and roll-control architecture.
Web / Process Force → Process Roll → Bearing Support → PFCL 201C → Measurement Electronics → PLC / Controller → Drive / Brake → Web Process
| System Element | Function |
|---|---|
| PFCL 201C | Measures mechanical force transferred through the roll support |
| Roll / Bearing Assembly | Transfers process force to the load cell |
| Measurement Electronics | Conditions and processes the load-cell signal |
| PLC / Controller | Processes force feedback and executes control logic |
| Drive / Brake | Adjusts the relevant machine operating condition |
| Web Process | Generates the mechanical force being monitored |
The actual architecture depends on the machine design, measurement electronics, controller, and tension-control strategy.

Installation and Maintenance
- Confirm the complete PFCL 201C 3BSE027070R20 reference before installation or replacement.
- Verify that the mechanical roll-support arrangement is compatible with the load cell installation.
- Check the mounting surfaces for contamination, damage, or conditions that could affect mechanical alignment.
- Ensure that the intended process force is transferred through the specified load path.
- Check for unintended mechanical contact, binding, or side loading that could affect the measurement.
- Verify the load-cell signal wiring, excitation connections, shielding, and grounding before commissioning.
- Route signal cables away from high-power motor and drive wiring where practical to reduce electrical interference.
- Perform a zero-load check after installation and before applying normal process loads.
- Verify the measurement response using an appropriate calibration or known-load procedure during commissioning.
- Monitor the force signal during operation for abnormal drift, sudden fluctuations, or values inconsistent with the actual process.
- Inspect the load cell, mounting structure, connectors, cables, and surrounding roll-support components during scheduled maintenance.
- When replacing the load cell, verify the complete ABB order number, mechanical configuration, measurement electronics, and control-system compatibility before installation.

Technical FAQs
What type of force does the PFCL 201C measure?
The PFCL 201C measures mechanical force transferred through its roll-support arrangement. In web-processing equipment, the measurement can be used for roll-force monitoring and web tension control.
Where is the PFCL 201C normally installed?
The load cell is installed as part of a roll-support or bearing arrangement. The mechanical structure should transfer the intended process force through the sensing element while minimizing unintended mechanical loading.
How is the PFCL 201C integrated with a control system?
The load-cell signal is connected to suitable measurement electronics, which provide the force information to a PLC, controller, or tension-control system. The control system can then use the measurement for monitoring, alarms, or closed-loop process regulation.
What should be checked when replacing a PFCL 201C?
Check the complete ABB order number, mechanical mounting arrangement, force measurement requirements, associated measurement electronics, wiring, and controller configuration. A similar-looking Pressductor load cell should not be assumed to be directly interchangeable without checking these parameters.
