What Is Tension Sensor?
Direct Answer
A tension sensor measures the force on moving web material in real time, enabling closed-loop control that prevents stretching or slack.
Key Takeaways
- A tension sensor measures the force on moving web material in real time, enabling closed-loop control that prevents stretching or slack.
- How it works: Load cells or dancer rollers measure web tension as nonwoven or film feeds through the line.
- Controlling nonwoven topsheet feed tension
- Tension control is only for elastics — it applies to all continuous web materials
How Tension Sensor Works
Load cells or dancer rollers measure web tension as nonwoven or film feeds through the line. The control system adjusts drive speeds to hold tension within tolerance, preventing stretching, misalignment and wrinkles.
Examples and Applications
- Controlling nonwoven topsheet feed tension
- Stabilizing film backsheet unwinding

Why measure web tension?
Inconsistent tension distorts material and causes wrinkles or misalignment; sensors enable automatic correction.
