Sensor roller PD 40

Sensor roller PD 40
Product description
  • Aluminum roller with fixed axis and 2 integrated load cells 
  • Assembly flange at one end for cantilever mounting •
  • Maximum operational reliability due to overload protection up to 10 times the nominal measuring force 
  • Different roller diameters from 60 to 120 mm ensure maximum flexibility 
  • In case of horizontal measuring direction, no influence on the measuring result due to the weight of the roller
