Application Fields
The PFEA112-20 is essential in industries where web tension must be strictly monitored:
- Pulp & Paper: Monitoring tension on paper machines and winders.
- Converting: Precise control for laminating, coating, and printing processes.
- Metal Processing: Managing tension in thin-foil rolling mills.
- Textile Industry: Ensuring uniform tension during fabric weaving and finishing.
Product Usage Instructions
- Mounting: Clip the unit onto a standard DIN rail inside a ventilated control cabinet. Ensure adequate spacing for heat dissipation.
- Wiring: Connect the load cells to the input terminals following the specific wiring diagram for your sensor model. Connect the 24V DC power supply to the designated power terminals.
- Calibration: Perform a “Zero Set” with no tension on the rollers. Follow with a “Span Calibration” by applying a known weight or tension to the load cells to calibrate the output signal.
- Signal Output: Configure the analog output (e.g., 4-20mA) to interface with your PLC or Drive system for closed-loop tension control.
- Diagnostics: Use the front-panel display to check for error codes if signal drift or communication loss occurs.
Q&A – Frequently Asked Questions
Q: What is the difference between the PFEA111 and PFEA112-20? A: The PFEA112-20 includes additional features such as a PROFIBUS-DP interface for digital communication, whereas the PFEA111 is primarily an analog-based controller.
Q: Can I use this with non-ABB load cells? A: While optimized for ABB’s Pressductor® technology, it can often be interfaced with other strain-gauge based sensors, though technical parameters must be matched carefully.
Q: Where can I get technical support or a quote for this specific model? A: You can access detailed technical support and procurement information through our ABB PFEA112-20 3BSE030369R0020 Resource Center.
