Application Scenarios & Pain Points
A tension measurement failure usually appears as a production problem first. Operators may see unstable web tracking, poor surface quality, or inconsistent winding before the sensor itself becomes the suspect.
Typical applications:
- Steel Processing Lines: Used on rolling, annealing, pickling, and galvanizing lines where strip tension control directly affects product quality.
- Paper Manufacturing: Provides roll force feedback for paper machines, coating lines, and winding equipment.
- Metal Foil Production: Supports tension regulation of thin materials where excessive force can cause deformation or breakage.
- Converting Equipment: Applied in continuous web handling systems requiring accurate tension feedback.
Field note: A finishing line experienced repeated tension alarms during high-speed operation. Mechanical inspection showed the roll assembly was intact, but the load measurement signal had drifted. Replacing the PFTL201C 50kN sensor and recalibrating the tension controller restored stable operation.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Incorrect Load Direction Installation
The PFTL201C measures horizontal force. Installing the sensor with incorrect force direction can produce unstable or incorrect readings.
How to avoid: Confirm mechanical drawings, roll force direction, and mounting orientation before commissioning.
⚠️ Calibration Data Mismatch
A replacement sensor may physically fit but require different controller scaling parameters.
How to avoid: Record the original sensor range, calibration values, and tension controller settings before replacement.
⚠️ Mechanical Mounting Stress
Excessive preload, misalignment, or uneven bolt tightening can affect measurement accuracy.
How to avoid: Check mounting surfaces, bearing housing alignment, and torque values during installation.
Frequently Asked Questions (FAQ)
What is the main function of the ABB 3BSE007913R50?
The sensor measures horizontal forces generated by strip tension on process rolls and provides force feedback for tension control systems.
Is the 50KN suitable for all tension measurement applications?
No. The 50 kN rating must match the mechanical load requirements of the application. Smaller or larger versions may be required depending on process conditions.
What industries commonly use the ?
Typical applications include steel processing, paper production, foil manufacturing, and other continuous web handling industries where material tension must be controlled accurately.
Can this sensor replace another ABB model?
Replacement depends on load rating, cable configuration, mounting arrangement, and controller compatibility. A 50 kN model should only replace another compatible 50 kN configuration.
What should be checked before purchasing this load cell?
Recommended checks:
- Complete ordering number
- Rated load requirement
- Measurement direction
- Mechanical mounting dimensions
- Existing tension electronics
- Calibration requirements
Why does a new load cell show unstable tension readings?
Possible causes include:
- Incorrect installation direction
- Mechanical stress on the sensor
- Damaged cable connection
- Incorrect controller scaling
- Poor calibration
Is a refurbished 3BSE007913R50 suitable for industrial use?
A tested refurbished unit can be suitable when it passes electrical checks, mechanical inspection, signal verification, and calibration testing before installation.
