Compact web tension sensor FI 7

Product Overview
The XW Machinery Through-Shaft Tension Sensor is designed for accurate web tension measurement in slitting, rewinding, printing, coating, laminating and converting applications. Using high-precision strain gauge technology, the sensor continuously detects web tension through the guide roller shaft and provides stable feedback signals for closed-loop tension control systems.

Design advantages

• Higher measurement accuracy
• Excellent linearity
• Low temperature drift
• Strong overload protection
• Long-term operational stability
• Easy installation and maintenance

Typical applications

• Slitting machines
• Rewinding machines
• Printing presses
• Coating machines
• Laminating machines
• Lithium battery production lines
• Flexible packaging equipment

Working principle
The axial tension detector measures the force applied to the guide roller by the moving web material. The built-in strain gauge sensing element converts the mechanical force into an electrical signal (mV/V), which is transmitted to a tension controller for automatic adjustment and closed-loop tension control.
