Rope tension system STF


  • Digital system for rope tensioning
  • For forestays and braces
  • Measuring range up to 300 Kg, with the possibilyty to get up to 3000 Kg
  • For outdoor applications

STF system has been designed to monitor tensioning of fixed wire ropes on forestays. It has to be applied on wire ropes with wire or textile ropes, with a diameter between 8 mm and 10 mm. Environmental protection IP65allows the sensor to be used in external applications.

Tensioning accepted by STF is up to 300 Kg, However, other product versions are available with a measuring range up to 3000 Kg.

STF is made up of a digital load cells (546QDT model) and two side plates. The rope on which measures are done can slide between the two sides. Digital output allows a simple connection for recording of measurements on PC or PLC.

System is extremely accurate (total error ≤10 Kg) and has a high reliability over time.

In general, this system is suitable for applications on braces or other rope plants.
