ABB PFRL101C‑1.0KN Pressductor Radial Load Cell

Product Description

PFRL101C‑1.0KN is an ABB Pressductor® magneto‑elastic radial load cell with nominal rated load of 1.0 kN. It adopts magneto‑elastic measuring principle instead of strain‑gauge deformation sensing, delivering high‑signal‑level low‑impedance AC output signal with excellent overload resistance and long‑cycle‑life performance. Designed for shaft‑mount installation under roll bearings, it measures radial force converted from web tension. Stainless‑steel housing with IP67 protection rating, operating temperature range from ‑20 °C to +80 °C, high resistance to shock and vibration for continuous‑running web‑processing production lines. Part of complete tension‑measuring system including junction box and ABB tension controller.

Product Features

• Shaft‑mount radial installation structure, easy assembly beneath rotating roll bearing housings
• Compatible with ABB PFEA series tension amplifiers and controllers for web‑tension closed‑loop control
• M12 connector interface, supports junction‑box multi‑sensor signal convergence
• Excellent shock and vibration resistance, suitable for 24‑hour continuous industrial production
• Can be used in pairs for full‑width web tension monitoring on processing machinery

Application Scenarios

• Web tension measurement for paper‑making, coating and calender production lines
• Plastic film, textile, printing and converting machinery roll‑shaft radial force monitoring
• Continuous processing production requiring stable closed‑loop tension control to avoid web break or wrinkle
• Packaging industry high‑speed unwinding and rewinding equipment tension feedback
• Industrial processing lines where high overload resistance and long service‑life are required
• Retrofit and spare‑part replacement for existing ABB Pressductor tension‑measuring systems

Common Problems & Troubleshooting

• Tension reading zero or no signal output: Check excitation power supply from tension controller; inspect M12 connector pin condition for loose or oxidation; verify cable integrity and no open‑circuit; confirm correct wiring between load‑cell and junction‑box.
• Measured value drift or unstable fluctuation: Check mechanical mounting installation; ensure roll bearing is free without jamming friction; inspect cable routing away from high‑power motor cables; check for condensation or moisture entering connector housing.
• Large measuring error, reading obviously deviate actual tension: Confirm correct radial‑force installation orientation; avoid pre‑tension or mechanical pre‑load on sensor; perform system calibration according to ABB procedure; check for mechanical deformation caused by excessive overload impact.
• Signal intermittent loss: Inspect M12 connector locking status under equipment vibration; check cable fatigue damage near connector; tighten junction‑box terminals; improve EMC grounding for measuring loop.
• Output still exists without web load: Eliminate mechanical pre‑stress caused by misalignment of roll shaft and mounting bracket; re‑adjust mechanical installation position and perform zero‑point recalibration.
• Damage after heavy overload impact: Though supporting 500 % overload, strong impact may cause internal magneto‑elastic element damage; perform calibration verification; replace load‑cell if error cannot be eliminated.
• Mismatch after spare‑part replacement: Use PFRL101C‑1.0 kN variant; do not mix‑use 0.5 kN /2.0 kN model without parameter modification on tension controller; verify junction‑box and amplifier parameter matching.
