Sensor roller PD 30

Product information

  • Aluminum roller with fixed axle and two integrated load cells
  • For straightforward installation between the side walls
  • Highly reliable in operation thanks to overload protection up to 10 times the nominal measuring force
  • Different roller diameters from 80 to 200 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
  • The high value of the web load cell spring constant permits a high maximum operating speed for the measuring roller
