Through-Shaft Tension Sensor for Web Tension Control

Through-Shaft Tension Sensor for Precise Web Tension Measurement

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.

Compared with conventional tension detectors, the through-shaft design offers:

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

The sensor is widely used in:

• Slitting Machines
• Rewinding Machines
• Printing Presses
• Coating Machines
• Laminating Machines
• Lithium Battery Production Lines
• Flexible Packaging Equipment

Proper web tension measurement helps eliminate wrinkles, telescoping rolls, material stretching and tracking issues while improving finished product quality.

High-Precision Axial Tension Detector for Web Tension Control Systems

The axial tension detector is designed for accurate web tension measurement in industrial roll-to-roll processing systems. It is widely used in slitting machines, rewinding equipment, coating lines, printing machinery, laminating systems, lithium battery production lines, and flexible material processing applications.

Using high-sensitivity strain gauge sensing technology, the detector converts web tension into stable electrical signals for closed-loop tension control systems. Accurate tension measurement is essential for maintaining stable web handling, reducing material waste, improving winding quality, and increasing production efficiency. Modern web tension systems commonly use load cells and tension transducers to monitor running web force in real time.

Industrial web tension systems commonly use load cells or tension transducers mounted on rollers to continuously measure web force and provide real-time feedback for automatic tension regulation.

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, which is transmitted to the tension controller for automatic adjustment and closed-loop tension control. Modern web tension systems widely rely on load-cell-based feedback technology for stable roll-to-roll processing.
