ABB PFVL141V-1.6MN is an industrial-grade, rectangular roll force load cell

The ABB PFVL141V-1.6MN is an industrial-grade, rectangular roll force load cell engineered specifically for metal rolling mills, heavy metallurgy, and profile extrusion systems. 

As a key hardware component within the ABB Millmate Roll Force System framework, this heavy-duty sensor delivers a nominal force measurement capacity of 1.6 MN (equivalent to 160 metric tons or 1.600 kN).

Unlike legacy piezo-resistive or standard bonded foil strain gauges that fail under aggressive, cyclical physical stress, the PFVL141V-1.6MN utilizes ABB’s proprietary Pressductor® magnetoelastic technology. 

By measuring changes in internal magnetic fields under structural compression, this solid-state transducer offers an incredibly stiff, non-contact internal measuring process that acts as an integrated building block within the mill stand window.

Product Advantages and Features

High Overload Resilience (Up to 700%): The heavy-duty steel structure utilizes minimal elasticity to achieve a massive safety factor.

 It survives severe impact loads from mill cobbles, cold-end strip entries, or sudden wrap-ups without zero-point displacement.

Unrivaled Immunity to Fluid & Scale Contamination: While typical industrial transducers fail when exposed to rolling emulsions and water, the Pressductor low-impedance technology operates flawlessly even with severe insulation degradation down to 10 kΩ.

Uniform Internal Force Distribution: Composed of a dense matrix of localized internal measuring zones, the block automatically averages the total vertical load.

 This ensures precise tracking even if the structural forces are applied eccentrically or unevenly across the plate surface.

True Signal Interchangeability: Every PFVL141V sensor block is factory pre-calibrated to a standardized output matrix

 This enables seamless, drop-in replacement during roll changes without time-consuming on-site system recalibration.

High Output Power & Low Impedance: The naturally low impedance (

Unique Product Description

The ABB PFVL141V-1.6MN transforms force diagnostic monitoring from a process vulnerability into a permanent structural advantage.

 Designed to act as an unyielding structural element within the mill stand layout,

 this rectangular block is armored with shrunk-on stainless steel protection strips that safeguard internal magnetic coils from chemical and physical wear.

 Free from aging strain-gauge adhesives, its solid-state core delivers absolute, drift-free reliability over millions of operational cycles. 

For harsh industrial plants seeking to minimize gauge variation and protect downstream tooling, this 1.6 MN block offers a perfect synergy of extreme structural stiffness and precise signal integrity.

Application Cases

Hot & Cold Steel Strip Mills: Positioned directly under the lower backup roll bearing block to monitor true roll-force split between the drive side (DS) and operating side (OS).

Hydraulic Automatic Gauge Control (AGC): Provides real-time, microsecond-range force feedback loops to dynamic screwdown cylinders, maintaining target metal foil or sheet thickness profiles.

Roll Eccentricity & Bearing Profiling: Constantly monitors high-frequency vibration patterns linked to backup roll out-of-roundness, allowing predictive roll replacement before pattern marks stamp onto the metal strip.

Structural Section & Pipe Extrusion Mills: Integrated beneath high-load leveling machinery, straighteners, and heavy profile drawing machinery to ensure mechanical force symmetry.
