Description
ABB PFCL201CE-10kN 3BSX105983100
I. Basic Information
Model: PFCL201CE-10kN, Part Code: 3BSX105983-100. It is an ABB Pressductor® magnetostrictive pillow-block load cell. Suffix CE denotes factory pre-assembled fixed cable with metal corrugated conduit sheath, optimized for heavy-duty high-vibration working conditions. It serves as critical stocked spare part for DCS systems in papermaking, metallurgical rolling mills and coal conveyor belt scales, supporting 24/7 non-stop production operation.
Product Positioning: Vertically loaded pillow-style force transducer mounted on roller bearing pedestals, silo support legs and belt scale base frames. It converts mechanical load into millivolt bridge signals and forms closed-loop constant-tension & weighing control systems when matched with ABB PFTL/PFTA transmitters. Models PFCL201C (with military plug connector) and PFCL201CD (PTFE anti-corrosion cable) of identical outline dimension cannot be directly interchanged; CE version is specially engineered for high-vibration rolling production lines.

III. Key Features
Armored Fixed Cable for CE Version: Crush & Pull Resistance, Customized for Rolling Mills
Full corrugated conduit wrapped cable outlet prevents wire breakage induced by field vibration. Different from pluggable Type C connector design, it eliminates on-site wiring work and fits high-speed reciprocating vibrating production lines.
Magnetostrictive Sensing Structure with Superior Shock Resistance vs Strain-gauge Load Cells
Internal sensing core stays intact against instantaneous impact from material dropping or conveyor startup/shutdown, delivering outstanding durability under harsh metallurgy and coal conveying environments.
Built-in Full-span Hardware Temperature Compensation for Long-term Zero Stability
Zero-point drift is minimized during long-term operation in high/low-temperature workshops and outdoor silo sites to reduce production downtime for regular zero calibration.
Identical Outline & Mounting Dimensions for Full Capacity Range Enabling In-place Retrofit Replacement
PFCL201CE shares consistent overall size and mounting holes with PFCL201C/CD. Only the load cell needs replacement for capacity modification without base frame rework during equipment renovation.
Full-loop Self-diagnosis with Fault Messages Uploaded to Master Controller via DP Bus
Transmitters detect short-circuit and overload faults; abnormal 4~20mA fault codes are uploaded to DCS HMI for alarming to realize rapid fault pinpointing of measuring points.
IV. Working Principle
- Mechanical Compression: Vertical load from rollers or silos squeezes the pillow block and deforms the internal magnetostrictive iron core.
- Magneto-electric Conversion: Core deformation changes coil magnetic flux; Wheatstone bridge outputs millivolt signal linearly proportional to applied load.
- Signal Conditioning: Weak millivolt signal is fed into dedicated ABB transmitters and converted to standard 4~20mA industrial analog signal.
- DCS Data Acquisition: Analog signal connects to AI modules; upper control system calculates actual tension or weight to realize PID constant-tension regulation and silo inventory interlock control.
V. Application Scenarios
(1) Metallurgical Cold Rolling / Pickling / Galvanizing Lines (Primary Application)
Roll stand tension measurement and closed-loop speed control for steel strip rolling. CE variant is prioritized for high-frequency vibrating high-speed rolling lines to avoid cable breakage issues existing on plug-type C version.
(2) High-speed Papermaking & Film Stretching Production Lines
Tension monitoring for press roll and coater bearing seats to prevent paper breakage and film tensile deformation.
(3) Belt Scales for Thermal Power & Coal Mine Conveying Systems
Load weighing for coal proportioning belts and loss-in-weight feeder flow control.
(4) Leg-mounted Weighing for Chemical Powder & Lime Silos
Real-time inventory monitoring of stored bulk material and automatic feeding interlock control.
Series Selection Differentiation
- PFCL201C: Detachable military plug outlet, applied for standard dust-free workshops;
- PFCL201CE: Conduit-armored fixed cable, for high-vibration rolling mills & conveyor belts;
- PFCL201CD: PTFE anti-corrosion cable, for chemical sites with acid & alkali corrosive atmosphere.
