Main Functions

Adopts ABB Pressductor magneto‑elastic measuring principle, precisely detects horizontal tension force of continuous web material, eliminates measurement disturbance from roller self‑weight
Converts mechanical web‑tension force into proportional analog electrical signal, transmits measured tension value to tension controller or PLC system for closed‑loop regulation.
High overload resistance; supports 50 % extended measuring range beyond nominal load, tolerates large transient overload without frequent recalibration or zero‑drift issue
Compact pillow‑block housing structure, direct mounting beneath idle roller shaft end. Mechanical structure isolates transverse vertical force, only responds to horizontal web‑tension component to guarantee measuring accuracy even with heavy rollers and low tension conditions
Robust mechanical construction for industrial harsh environment; resists vibration, dust and minor mechanical impact. Delivers stable output for continuous dynamic tension measurement during acceleration, deceleration and steady‑speed running of production line.
Works cooperatively with ABB tension controllers, realizes real‑time tension monitoring, alarm trigger for over‑tension / under‑tension events.More products: www.plcva.com

ABB PFTL301E Part No.3BSE019050R500 Tension Sensor

Specialized web‑tension measuring component for web‑processing industries: paper‑making, printing, coating, laminating, film slitting, textile and battery‑electrode production lines.
Installed at both ends of idle guide roller, measures horizontal tension of moving strip material. Provides feedback signal for drive system closed‑loop tension control, keeps web tension stable to avoid web breakage, wrinkling, stretching and product dimension deviation.
Applied in converting production lines to improve finished‑product consistency, reduce scrap rate and enhance overall production uptime.
Part number 3BSE019050R500 is original OEM spare unit. Used as replacement spare part for production‑line maintenance. Restores web‑tension measuring capability when original load cell fails, minimizing unplanned production downtime.
