Country of Origin
This unit is manufactured by ABB in Sweden, maintaining the high quality and precision standards of their Force Measurement division.
Application Fields
The PFEA112-65 is essential for precision web and strip tension control:
- Paper and Board Industry: Controlling the tension of the paper web during winding, coating, and calendering.
- Metal Processing: Managing strip tension in rolling mills and slitting lines.
- Plastic Film Industry: Ensuring consistent tension during extrusion and laminating processes to prevent material stretching.
- Printing and Converting: Maintaining registration and print quality through stable tension control.
Product Usage Instructions
- Mounting: Secure the IP65 enclosure to a rigid wall or machine frame near the load cells. Ensure there is enough clearance to open the front cover for wiring.
- Load Cell Wiring: Connect the Pressductor load cells to the internal terminal blocks. Use ABB-specified shielded cables to prevent signal interference.
- Calibration: Use the front-panel display to perform a “Zero-set” (with no load) and a “Hanging Weight” or “Manual” calibration to define the full-scale tension value.
- Analog/Digital Setup: Configure the analog outputs to match your drive system or PLC input requirements (e.g., 4-20mA for 0-1000N).
- PROFIBUS Integration: If using digital communication, set the PROFIBUS address via the menu and ensure the GSD file is correctly loaded into your PLC hardware configuration.
Product Technical Description
The PFEA112-65 serves as a high-speed signal processor for ABB’s unique Pressductor technology. Technically, it provides the excitation current to the load cells and processes the resulting low-level signal into a highly stable, linear output. The “112” series is a “Control” version, meaning it includes advanced features like sum/difference calculation and PROFIBUS connectivity. The IP65 housing eliminates the need for an additional protective cabinet, significantly reducing installation time and costs in harsh mill environments.
Q&A (Common Questions)
Q: Can I use the PFEA112-65 with standard strain-gauge load cells? A: No. This unit is specifically designed for ABB’s Pressductor load cells, which operate on the principle of magnetoelasticity.
Q: What is the maximum distance between the load cells and the PFEA112-65? A: Using standard ABB cables, the distance can typically be up to 50 meters (164 ft) without signal degradation.
Q: Does the IP65 rating mean it can be submerged? A: No. IP65 protects against heavy spray and dust, but it is not rated for continuous submersion (which would require IP68).
Q: How do I clear a “Sensor Error” (SE)? A: This usually indicates an open or short circuit in the load cell wiring. Check all terminal connections and measure the resistance of the load cell coils as specified in the manual.
