Description
Product Introduction
The ABB PFTL101A-0.5kN (3BSE004160R1) is a Pressductor PillowBlock load cell designed for horizontal force measurement in continuous web processing lines. It mounts directly under idler roll bearing housings, measuring the tension force exerted by moving material in paper machines, printing presses, and film lines.
This load cell uses ABB’s magneto-elastic measurement principle rather than bonded strain gauges. The sensing element is machined from a solid stainless steel block, eliminating drift and eliminating the need for periodic recalibration. With a 30:1 measuring range and high spring constant, the unit handles heavy roll weights and high line speeds without mechanical resonance issues.
Frequently Asked Questions
Q: Is this load cell obsolete? What are my options?
A: Yes, ABB has declared the PFTL101 series end-of-life. No direct drop-in replacement exists under the same form factor. In our experience, the realistic path is sourcing verified New Surplus or refurbished units from the secondary market. If you need a long-term migration strategy, plan for a complete tension measurement system overhaul—not just a sensor swap.
Q: What is the most common mistake when replacing a PFTL101A?
A: Honestly, the most common mistake is ignoring the mounting alignment. This load cell is sensitive to side loads and bending moments. If the bearing housing sits crooked or the mounting bolts are over-torqued unevenly, you will get zero drift and nonlinear readings. Photograph the old installation, check the shaft alignment, and torque the bolts in a star pattern. The 0.015 mm deflection spec means mechanical precision matters.
Q: Does this require external signal conditioning?
A: Yes. The PFTL101A is a passive sensor—it outputs a raw signal proportional to force, not a 4-20 mA loop signal. You need an ABB tension controller or a compatible amplifier card to excite the transducer and condition the output. Do not try to wire it directly to a standard PLC analog input. Verify the excitation voltage and signal range against your existing controller before ordering.
Q: What about wiring and cable condition on surplus units?
A: The standard PFTL101A uses a fixed connection cable. On surplus stock, inspect the cable jacket carefully for cuts, kinks, or UV degradation. The cable entry point is a common failure location—flexing during roll changes eventually breaks the internal conductors. If the cable is damaged, the sensor is effectively dead. Ask the supplier for a continuity check before shipment.
Q: Warranty and lead time?
A: Standard warranty on tested surplus stock runs 12 months. Lead time depends on your region and whether the exact variant (standard A vs. mill duty AE) is in the warehouse. Most orders ship within 3–5 business days. State your required protection class and cable length in the PO. The standard IP65 version is not a drop-in for the IP66 mill duty variant in wash-down environments.
