Key Technical Specifications

Note: Exact protection rating, cable type, connector, and overload limit depend on the specific suffix and revision. Some aftermarket listings attach generic 4–20 mA, Modbus, or strain-gauge descriptions to PFTL201C, but the genuine ABB Pressductor version outputs a low-impedance AC signal that must be processed by compatible tension electronics. Confirm against the nameplate and ABB datasheet before commissioning.

Product Introduction

The ABB PFTL201C-50.0 (3BSE007913R50) is a 50 kN Pressductor Pillow Block load cell designed for horizontal web tension measurement. It is installed between the measuring roll bearing housing and the machine frame, converting the horizontal force component generated by web tension into a measurable signal.

It uses ABB’s Pressductor piezomagnetic technology, which produces a high-power, low-impedance AC signal that is inherently resistant to electrical interference and ground faults. Because the measurement principle does not rely on mechanical deformation or moving parts, the sensor maintains long-term stability and tolerates repeated overload without significant drift.

This 50.0 kN version is typically used in paper machines, calenders, coaters, winders, metal strip processing lines, foil and film converting lines, and other applications where medium-to-high tension levels must be measured at high operating speeds. It is commonly paired with ABB PFEA111, PFEA112, or PFEA113 tension electronics and PFEL series units to form a complete tension control loop.

For MRO buyers, PFTL201C-50.0 is typically replaced when a tension system shows unstable readings, zero drift, sensor open/short alarms, or physical damage to the load cell body or cable. Because the order code 3BSE007913R50 corresponds specifically to the 50.0 kN C-series unit, it should not be substituted with 10.0 kN or 20.0 kN versions without recalibration and system verification.

QA & Testing SOP

1. Nameplate verification — Confirm PFTL201C-50.0 and full order code 3BSE007913R50.
2. Visual inspection — Check the load cell body, mounting holes, cable/connector, and sealing for mechanical damage or corrosion.
3. Coil resistance check — Measure excitation and signal coil resistance against ABB reference values.
4. Insulation test — Verify insulation between coils and the load cell body.
5. Zero signal check — With no load applied, confirm a stable baseline signal.
6. System integration test — Install with PFEA111/112/113, set Nominal Load to 50.0 kN, and verify stable tension readings after tare compensation.
7. Direction verification — Confirm that applied force produces a positive tension signal; reverse signal wires if necessary.

All units ship in anti-static/anti-shock packaging. A test log can be provided on request.

Installation Pitfalls & Guide

Match the 50.0 kN rating. 3BSE007913R50 is the 50.0 kN version. Replacing it with a 10.0 kN or 20.0 kN unit will cause incorrect scaling and possible overload alarms.

Confirm C / CE / CD variant. Standard PFTL201C uses a cylindrical connector; CE/CD variants offer different cable configurations for harsher environments. Do not assume environmental rating from the base model alone.

Install in the correct measuring direction. PFTL201C is a horizontal load cell. Vertical installations require PFCL-type cells.

Tare the roll weight. The measuring roll and bearing weight must be compensated in the PFEA/PFEL electronics so that only web tension is measured.

Set Nominal Load correctly. In PFEA111/112/113, set Nominal Load to 50.0 kN to match the load cell rating.

Protect signal wiring. Keep sensor cables away from power cables and VFD outputs to avoid induced interference.

Replacement steps:

1. Lock out the line and relieve mechanical load from the roll.
2. Photograph wiring and note coil terminal assignments.
3. Remove the old load cell and inspect mounting surfaces.
4. Install the replacement PFTL201C-50.0 with proper alignment.
5. Reconnect wiring and verify coil resistance.
6. Power up the PFEA/PFEL unit, set parameters, tare the roll weight, and validate tension readings.

Technical FAQ

.0 the samL201C-10.0 or -20.0? No. 3BSE007913R50 is the 50.0 kN version; 10.0 kN and 20.0 kN versions carry different suffix codes (e.g., 3BSE007913R0010 for 10 kN). They are not directly interchangeable without recalibration.

Does this sensor output 4–20 mA directly? No. The PFTL201C is a Pressductor piezomagnetic load cell that outputs a low-impedance AC signal. It requires compatible tension electronics (PFEA/PFEL series) to convert the signal into a usable tension value or analog output.

What is the overload capacity? The extended load is 75.0 kN (1.5× nominal), and the permitted transverse load is 250.0 kN. Pressductor technology inherently tolerates high overload without permanent damage.

What companion electronics does it work with? It is compatible with ABB PFEA111, PFEA112, PFEA113 tension electronics and PFEL111/112/113 measurement units.

Do you stock single units? Yes. Single units are available for MRO replacement; matched pairs and project quantities can be quoted on request.
