Brief Product Description

PFVL141V 25.0 MN, part number 3BSE024995R2500, is a heavy‑duty rectangular Pressductor® magnetoelastic load cell within ABB Millmate roll‑force measurement series. With 25 MN nominal measuring capacity, it is installed beneath the backup‑roll bearing housing of rolling mills to measure total rolling force. Without strain‑gauge adhesive components, it features high overload tolerance up to 700 %, low‑impedance signal output and strong resistance to insulation degradation and electromagnetic interference. Factory pre‑calibrated for interchangeability, this robust sensor works with Millmate controller units for automatic gauge control, and serves as key spare replacement component for metallurgical rolling‑mill maintenance and retrofit projects.

Core Product Functions

• High‑precision roll‑force measurement based on Pressductor® magneto‑elastic effect, converting mechanical rolling load into standard electrical signal
• Accurately detect force distribution between drive‑side and operator‑side of mill stand for roll‑gap calculation and AGC automatic gauge control
• Strong overload resistance, tolerating up to 700 % short‑term overload without permanent mechanical damage
• Low‑impedance output maintains valid measurement even with degraded insulation down to 10 kΩ level, resisting on‑site environmental interference
• Multi‑zone internal sensing structure automatically averages uneven and eccentric load applied across the sensor surface
• Factory calibrated output allows direct interchange of same‑specification load cells without complex on‑site recalibration
• Monitor backup‑roll bearing conditions and roll eccentricity to assist equipment fault early warning
• Stainless steel side‑bar protection shields internal magnetic coils against mechanical impact, dust and moisture in harsh mill environment
• Seamless signal connection with ABB Millmate controller system for real‑time data uploading to rolling‑mill automation platform

Application Scenarios

• Hot‑rolling and cold‑rolling mill stands in steel metallurgy plants for roll‑force monitoring and AGC control
• Heavy‑duty metal processing mills including plate mill, strip mill and pipe rolling production lines
• Steel plant rolling‑mill automation systems equipped with ABB Millmate roll‑force measuring solution
• Heavy‑load material forming equipment requiring high‑accuracy large‑tonnage force detection
• Process monitoring for rolling‑mill bearing health assessment and roll‑eccentricity diagnosis
• Spare replacement load cell for maintenance and upgrade of existing PFVL141V‑based mill measurement installations

FAQ (Frequently Asked Questions)

• Q: Force reading shows zero value or unstable jump during mill operation?
  A: Inspect sensor cable damage, connector loose contact, cable insulation deterioration, mechanical offset installation or failure of matching Millmate controller unit.
• Q: Measurement deviation becomes larger after long‑time running?
  A: Check mechanical flatness of mounting base, foreign object stuck between load cell and bearing housing, excessive eccentric load, or cable aging.
• Q: Can PFVL141V be replaced while rolling mill remains in production status?
  A: Not allowed. Stop mill equipment, release mechanical pressure and follow metallurgical safety procedures before sensor disassembly and replacement.
• Q: Can ordinary strain‑gauge load cell substitute PFVL141V 25.0 MN?
  A: Not recommended. Pressductor magneto‑elastic working principle, overload capacity, impedance characteristics and calibration standard are special for Millmate system, generic sensors cannot match system requirements.

• Q: Is PFVL141V 3BSE024995R2500 available for brand‑new rolling‑mill projects?
  A: This legacy Millmate rectangular load cell reaches end‑of‑life. Only surplus and fully‑tested refurbished units are supplied for existing‑site maintenance work.
