Sensor roller PD 30

Sensor roller PD 30
Product description
  • Aluminum roller with fixed axis and two integrated load cells 
  • For easy assembly between side walls. Optionally with securing kit or snug-fit shoulder screws 
  • Maximum operational reliability due to overload protection up to 10 times the nominal measuring force 
  • Different roller diameters from 80 to 200 mm ensure maximum flexibility 
  • The roller weight does not influence the measuring result, assuming a horizontal direction of measuring
