The ABB 3BSE004191R1, also designated PFTL101B‑5.0kN, is a high‑precision industrial load cell for web tension and force measurement systems. It converts mechanical tension and pressure into standard measurable electrical signals for closed‑loop process control. Built with stainless‑steel hermetically‑sealed housing, it delivers stable measuring performance under heavy‑industry conditions with strong anti‑vibration capacity. It adopts bolt‑on mounting structure for convenient field installation and replacement. Widely deployed in paper‑making, metallurgical rolling mills and continuous production lines for real‑time tension monitoring. As a key measuring spare part for legacy industrial tension control systems, each unit undergoes strict calibration and full‑function testing before shipment for equipment overhaul and system maintenance.
