The PFTL 101A (Part Number: 3BSE004166R1) is a high-accuracy Pressductor load cell from ABB. It is specifically designed for precise web tension measurement in industrial converting, paper, and printing lines. The 1.0 kN rating allows it to handle medium-load applications with exceptional reliability, providing long-term stability even in harsh industrial environments.

🛠️ Mechanical Installation Requirements

• Mounting: The load cell must be mounted on a rigid, flat surface. Ensure the load cell is oriented so the force acts strictly in the measuring direction (perpendicular to the load cell top).

• Spatial Clearance: Ensure there is no physical contact between the mounted roll/bearing housing and the frame other than through the load cell itself. Any “bridging” will result in measurement errors.

• Surface Flatness: The support surface must be machined flat to ensure even distribution of the load, preventing internal stress and measurement drift.

⚡ Electrical Wiring Guidelines

• Terminal Definition: Connection is typically made via a rugged, industrial-grade connector. Pin 1-4 correspond to the excitation and signal output (bridge circuit).

• Wire Gauge: Use high-quality, shielded, twisted-pair cabling. Since the signal is a low-level bridge output, minimizing resistance and interference is paramount.

• Grounding: Maintain a single-point ground connection for the cable shield at the electronics unit (PFEA) to prevent ground loops that could introduce signal noise into the tension control system.

🌐 Communication & Setup

• Calibration: Once installed, the PFTL 101A requires calibration against the tension electronics (e.g., ABB PFEA series). Perform a “Zero” and “Span” calibration using known weights or reference tension values.

• Configuration: In the PFEA software, input the sensitivity constant (mV/V) provided in the individual calibration certificate that accompanies the load cell.

❓ Frequently Asked Questions (Q&A)

• Q: What does “Pressductor” technology offer over strain gauges? A: Pressductor technology is based on magneto-elastic effects, making the load cell virtually indestructible under normal operating conditions and highly resistant to electrical overloads and mechanical shocks.

• Q: Can I mount the PFTL 101A in any orientation? A: No, it must be mounted according to the arrow marked on the unit, which indicates the direction of the force to be measured.

• Q: Is this unit maintenance-free? A: Yes, once properly installed and calibrated, the PFTL 101A is essentially maintenance-free. Periodic checks should only involve ensuring that the mounting bolts remain tight and the area is free of debris.
