ABB PFTL301E – Horizontal Pressductor PillowBlock Tension Load Cell
Product Overview
This pillow-type load cell adopts ABB proprietary Pressductor magnetoelastic sensing technology, dedicated to independent horizontal web tension measurement in continuous roll processing lines. It separates horizontal tension signals from vertical roll weight interference, solving low-precision detection issues of traditional vertical load cells under heavy roller and light tension working conditions. With stainless steel sealed housing and stable long-cycle performance, it delivers consistent tension feedback for paper, textile, plastic film and metal foil production to reduce web breakage and stabilize finished product quality.

ABB PFTL301E
Key Features and Benefits
- Horizontal single-axis measurement eliminates roll weight offset, maintaining high effective measuring range utilization even with light tension loads
- Magnetoelastic sensing structure tolerates 300% nominal overload without permanent deformation, extending service life in fluctuating tension processes
- Low thermal drift and minimal signal creep cut regular recalibration frequency for long-term continuous production
- Compact mini-series footprint shares installation dimensions with standard vertical load cells for direct field replacement
- Hermetically sealed stainless steel body resists dust, moisture and production fluid splashes in wet processing workshops

Installation and Maintenance
Align the sensor’s horizontal measuring arrow with web running direction during roller bracket installation, and fasten mounting bolts evenly to avoid eccentric force input. Route shielded signal cables separately from power cables to reduce electromagnetic interference.
Daily maintenance only requires surface dust removal; quarterly inspection checks cable connector tightness and signal output linearity. No frequent zero calibration is required under normal operating environments.
