Benefits

Siemens SIWAREX WL280 RN-S SA load cell range, featuring innovative ring torsion spring technology crafted from stainless steel. With two strain gauge spirals meticulously applied to the upper and lower faces of the ring, this load cell guarantees accurate measurements. Under the influence of centrally applied loads, the spring element undergoes deformation, compressing the upper face’s strain gauge while extending the lower face’s strain gauge. This results in a detectable change in electrical resistance, meticulously captured by a bridge circuit.

Benefiting from integrated overload protection for rated loads up to 13 tons (12.79 tons), these load cells offer unparalleled safety and reliability. Ideal for a diverse range of applications, including hopper, belt, platform, and roller conveyor scales, the SIWAREX WL280 RN-S SA load cell range ensures precise measurements and consistent performance in various industrial settings.

  • Advanced Ring Torsion Spring Design: The load cell features a unique ring torsion spring made of stainless steel, ensuring exceptional durability and reliability in various industrial environments.
  • Accurate Measurement: Equipped with two strain gauge spirals on the upper and lower faces of the ring, the load cell delivers precise and consistent measurements, even under heavy loads.
  • Integrated Overload Protection: All load cells within the range, up to 13 tons, come with integrated overload protection, enhancing safety and preventing damage to the equipment.
  • Versatile Application: Designed for hopper, belt, platform, and roller conveyor scales, the SIWAREX WL280 RN-S SA load cell offers versatile application possibilities, catering to diverse industrial weighing needs.
