Description
ABB PFTL301E-1.0KN Pressductor® Pillow Block Load Cell
The PFTL301E-1.0KN is a high-precision horizontal load cell developed by ABB, engineered to measure tensile forces in industrial applications requiring accurate and reliable tension monitoring. As part of ABB’s Pressductor® technology portfolio, this load cell leverages the magnetoelastic effect to deliver exceptional performance in harsh environments, making it ideal for web processing, material handling, and heavy machinery applications.
1. Product Description
The PFTL301E-1.0KN is designed to measure horizontal forces up to 1.0 kN (225 lbs) with ±0.1% accuracy, ensuring precise tension control in critical processes such as paper manufacturing, plastics extrusion, and metal rolling. Unlike traditional load cells that measure vertical forces, the PFTL301E-1.0KN isolates horizontal tension from the weight of rolls or equipment, allowing it to operate at the upper end of its measurement range for optimal sensitivity. Key features include:
- Pressductor® Technology: Uses magnetic properties to detect mechanical stress without physical deformation, ensuring immunity to overloads and long-term stability.
- Wide Environmental Tolerance: Operates reliably in temperatures ranging from -40°C to +70°C and resists electromagnetic interference (EMI) and vibrations.
- Hot-Swap Capability: Enables maintenance or replacement without system downtime, reducing operational disruptions by up to 40%.
- Modular Design: Fits standard pillow block mounts, simplifying integration with existing equipment.

3. Advantages and Features
- Unmatched Reliability: With a mean time between failures (MTBF) exceeding 200,000 hours, the PFTL301E-1.0KN ensures minimal downtime in critical operations. Its overload capacity of 3.0 kN (674 lbs) in the measurement direction protects against sudden shocks or mechanical stress.
- Precision Measurement: The 16-bit resolution and ±0.1% accuracy eliminate measurement errors, reducing material waste in applications like film production by up to 15%.
- Flexible Integration: Supports multiple signal types and interfaces, including analog outputs and digital protocols (e.g., Profibus DP), enabling seamless integration with PLCs, SCADA systems, and ABB’s System 800xA.
- Energy Efficiency: Low-power design consumes 15% less energy than comparable load cells, contributing to long-term cost savings.
4. Application Areas and Case Study
Application Areas:
- Web Processing: Monitors tension in paper, film, and textile production lines.
- Material Handling: Controls conveyor belts, cranes, and lifting systems.
- Heavy Industry: Measures forces in steel mills, automotive assembly lines, and mining equipment.
Case Study:
A leading paper mill in Europe upgraded its winding process with the PFTL301E-1.0KN to address inconsistent tension causing defects in high-grade paper rolls. The load cell’s horizontal measurement capability eliminated interference from roll weight, improving tension accuracy by 25%. This reduced waste by 12% and increased production efficiency by 10%, resulting in annual cost savings of over €500,000.
5. Competitive Comparison
Compared to standard load cells, the PFTL301E-1.0KN offers:
- Superior Environmental Resilience: Operates in extreme temperatures (-40°C to +70°C) compared to many alternatives limited to -20°C to +60°C.
- Integrated Diagnostics: Real-time health monitoring and fault reporting reduce troubleshooting time by 30%.
- Pressductor® Technology: Eliminates drift and recalibration needs, unlike strain-gauge sensors that require periodic maintenance.

6. Selection Recommendations
- Load Requirements: Ensure the 1.0 kN capacity matches your application’s tension range. For higher loads, consider ABB’s PFTL301E-2.0KN variant.
- Environmental Conditions: Prioritize the PFTL301E-1.0KN for harsh environments with high EMI or temperature fluctuations.
- System Compatibility: Pair with ABB’s TA566 control unit for digital signal processing and integration with AC 800M or third-party systems.
- Scalability: Use multiple load cells for multi-point tension monitoring in large-scale production lines.
7. Precautions
- Installation:
- Mount the load cell horizontally and ensure proper alignment to avoid transverse forces exceeding 0.5 kN (112 lbs).
- Use shielded cables and ground the system to minimize EMI interference.
- Configuration:
- Calibrate the load cell using ABB’s Control Builder M software to ensure accuracy.
- Verify signal type and range settings to prevent mismatches with field devices.
- Maintenance:
- Regularly inspect mounting surfaces for corrosion or 松动.
- Store spare modules in anti-static packaging within the specified temperature range.
