The RS Series Web Tension Loadcells are specially designed for precise tension measurement in various web processing applications, such as printing, laminating, coating, and packaging. These sensors help maintain consistent web tension, which is essential for process stability and material integrity.
The RS series includes five model types: RS1, RS2, RS3, RS4, and RS5. Please note that the RS4 has been discontinued and is no longer part of our production line.
All RS loadcells are designed to deliver high accuracy, robust mechanical construction, and easy integration into different web path layouts.
The RS Series Web Tension Loadcells operate by accurately measuring tension in continuously processed materials (webs or sheets). Precise tension measurement ensures stable production, prevents material damage, and enhances overall product quality by maintaining consistent tension levels throughout the process. Working Principle
RS Loadcells measure tension by detecting the force applied to a roller around which the web passes. This roller is either directly clamped (RS2 & RS5) or bearing-mounted (RS1 & RS3) onto the loadcell body. As the web exerts tension, the loadcell converts this mechanical force into an electrical signal, proportional to the applied tension. The electrical output is then processed by control systems to adjust motors and maintain the desired tension.
Single or Dual Mounting: Suitable for both single (narrow webs < 100 mm) or dual-loadcell configurations (wide webs). Dual setups offer greater accuracy for wider applications.
The RS Series Loadcells are categorized into four primary models: RS1, RS2, RS3, and RS5. Each model offers unique design characteristics and advantages tailored to specific web tension applications.
The RS1 and RS3 models feature a bearing-type design, incorporating internal bearings that facilitate smooth and precise tension measurement. Key characteristics include:
RS2 and RS5 models use a clamp-type design, providing ease of installation and flexibility in web tension systems:

A load cell is a transducer that converts mechanical force into an electrical signal. It is commonly used in weighing systems and force measurement applications to provide accurate and reliable data.
Load cells operate based on the principle of strain gauges. When a force is applied, the strain gauges deform, causing a change in electrical resistance. This change is measured and converted into an electrical signal proportional to the applied force.
Common types include:
Key considerations include:
A web tension load cell is designed to measure the tension in materials like paper, film, or textiles as they move through processing equipment. Accurate tension measurement ensures product quality and prevents material damage.
Web tension load cells are specifically engineered to handle dynamic forces in continuous processing lines. They often feature specialized mounting options and enhanced sensitivity to detect slight variations in tension.
They are widely used in industries such as:
Proper installation is crucial:
Regular maintenance includes:
Yes, many web tension load cells are designed for easy integration with existing control systems and can be customized to fit specific application requirements.
Correct installation ensures maximum measurement accuracy, reliability, and extends the lifespan of the loadcell, minimizing downtime and maintenance costs.
The force direction must be correctly aligned according to the loadcell’s markings to ensure accurate tension measurement and prevent damage.
Yes, a dual-loadcell configuration is highly recommended for wide web applications. This ensures balanced tension measurement and greater accuracy.
Applying force vertically ensures optimal accuracy by aligning the tension direction with gravity, minimizing measurement errors caused by angular forces.
Proper alignment and secure fastening of clamps and bearings are essential to avoid mechanical stress, inaccurate readings, and premature loadcell failure.
Using a single loadcell for wide web applications can result in inadequate support, leading to inaccurate tension measurement, uneven wear, and potential system failures.
Misaligned force directions cause inaccurate readings, reduce system efficiency, and may lead to permanent damage to the loadcell.
Non-vertical force application reduces measurement accuracy due to angular forces interfering with correct tension sensing, resulting in unreliable data.
Insufficient fastening leads to instability and inaccurate measurements, whereas overly tight fastening induces mechanical stress and distortion of signals, adversely affecting loadcell performance.
Tension load cells have become an essential tool across multiple industries, ensuring precision and reliability in critical processes. In the packaging industry, tension load cells help maintain consistent material tension, enhancing product quality and reducing waste. The printing industry relies on these sensors to achieve uniform tension, vital for high-quality output and minimal downtime.
In textiles, tension load cells accurately control yarn tension during weaving and winding, ensuring fabric integrity and consistency. Similarly, in paper production, they prevent breakage and tearing by continuously monitoring web tension. In the cable industry, tension load cells play a crucial role in maintaining precise tension control, ensuring cable uniformity and preventing deformation during production. Their adaptability makes tension load cells indispensable in any industrial environment where consistent tension is critical.
Tension load cells offer significant advantages in applications that require precise measurement and control of tension forces. One key benefit is their exceptional accuracy, allowing industries to maintain optimal tension levels, thus preventing costly production errors and material damage.
Additionally, these load cells feature robust construction, making them suitable for harsh industrial environments, providing long-term reliability with minimal maintenance. Another advantage is their ease of integration; tension load cells can seamlessly connect with existing machinery and control systems, enabling efficient upgrades to production processes. Overall, these benefits translate into enhanced productivity, improved quality control, and significant cost savings for manufacturers.
