Sensor roller PD 40

Product information

  • Aluminum roller with fixed axle and two integrated load cells
  • Mounting flange at one end for cantilever mounting
  • Highly reliable in operation thanks to overload protection up to 10 times the nominal measuring force
  • Different roller diameters from 60 to 120 mm ensure maximum flexibility
  • For measurements in a horizontal direction, the weight of the roller does not affect the measured result
  • Good thermal behavior and high degree of linearity of the measuring elements due to strain gauge application on a flat surface
