Description
Product Overview
The ABB PFRL101C is a Pressductor radial load cell designed to measure force applied through a shaft-mounted roller in web-processing machinery. It converts mechanical loading into an electrical measurement signal that a compatible tension-measurement controller can process. Typical installations include paper machines, plastic-film lines, printing presses, textile equipment, coating systems, and slitting or winding machinery. By measuring the force acting on a roller, the system helps operators monitor web tension and maintain process consistency.
The PFRL101C uses ABB Pressductor technology, based on the magneto-elastic effect: applied mechanical force changes the magnetic properties of the sensing material, producing a measurement signal. ABB specifies radial measurement, a nominal-load range of 0.5–2.0 kN across the PFRL101C variants, an accuracy class of ±0.5%, and a deflection of 0.01 mm. The product’s overload capacity depends on the selected nominal rating and the direction of applied force. These characteristics make the load cell suitable for demanding web-tension applications where repeatable force measurement and mechanical durability matter.
When sourcing the ABB PFRL101C, the nominal load rating must be confirmed rather than inferred from the base model alone. ABB documentation lists 0.5 kN, 1.0 kN, and 2.0 kN options, and these variants have different permissible load limits. The installation dimensions and mounting bracket must also match the existing roller assembly. Confirm the full product label, rated capacity, mounting arrangement, cable condition, and compatibility with the installed tension controller before ordering. A matching model family does not guarantee that a different capacity variant can be substituted without recalibration or mechanical changes.
Product Introduction
Unstable web tension can lead to wrinkles, tracking problems, and inconsistent winding or coating results. The ABB PFRL101C measures radial force on a roller assembly, providing input for compatible web-tension control systems. Its nominal-load options range from 0.5 to 2.0 kN, depending on the selected variant.
Before replacing the sensor, confirm the rated capacity, mounting dimensions, measuring direction, and controller compatibility. The load rating must match the mechanical design, not simply the original part-family name.

Frequently Asked Questions
Q1. What is the ABB used for?
It measures radial force on a shaft-mounted roller, typically as part of a web-tension measurement system. Common applications include paper, film, printing, coating, and winding machinery.
Q2. What load ratings are available for the ?
ABB lists nominal-load variants of 0.5 kN, 1.0 kN, and 2.0 kN. The extended-load and overload limits differ by capacity, so verify the exact variant before purchase or installation.
Q3. Can I replace a with a PFRL101B?
Not without checking the rating and mechanical fit. The PFRL101B is listed at 1.0 kN nominal load, while the family includes multiple capacity options. The correct choice depends on the installed sensor’s rated capacity and mounting arrangement.
Q4. Does the connect directly to a PLC?
Do not assume direct connection. The load cell is normally part of a measurement chain that includes a compatible tension-measurement controller or signal-conditioning equipment. Confirm the electrical interface and controller requirements for the installed system.
Q5. How should the sensor be installed and calibrated?
Follow ABB’s mounting instructions and ensure the sensor is loaded in the specified radial direction. Check the roller geometry, alignment, mounting hardware, and cable routing. After installation, perform the required zeroing and calibration procedures through the compatible measurement system.
Q6. How can I verify that a replacement load cell is genuine and functional?
Check the ABB label, full model designation, rated capacity, and order number. Inspect the mounting surfaces and cable, and request any available traceability or functional-test records. Visual condition alone does not establish measurement accuracy.
Q7. Does new-surplus status guarantee factory-sealed packaging or a warranty?
No. Ask the supplier to confirm the actual condition, packaging, inspection or test history, warranty period, and return terms in writing. For a load cell, confirm the rated capacity and mechanical condition before accepting it as a replacement.
