Fabric tension sensor PD 77

Product information

  • Fabric tension sensor with bearing bracket for external measurement on guide roller
  • High-grade steel version for wire and press section, steel version for dryer section
  • Pivot point bearing can be lubricated
  • Highly reliable in operation thanks to mechanical overload protection
  • Nominal measuring forces from 1 to 90 kN ensure a high degree of flexibility
  • Integrated damping element prevents zero point drift due to impacts and machine vibrations
