Potentiometric Displacement Sensor Option Protection Class IP67 Technical changes reserved. All data sheets at www.burster.com Plug or cable connection Electromagnets Deformations - bending Pneumatic cylinders Length tolerances Press-insertions (longitudinal press-fits) Feed strokes Machine hubs Punch, knee lever or extruder distances Hydraulic cylinders Application fields include Due to its high resolution also when measuring long distances, linear displacement measurements up to 900 mm can be carried out. Conversions between rotatory and translation movements through ball screws, wire or cord connections and so on are not necessary for direct displacement measurement. Measuring ranges: between 0 ... 50 mm and 0 ... 900 mm Optional protection classes IP65 and IP67 Description Due to the technology employed in potentiometric displacement sensors, they always operate with a sliding contact system. Special processes are applied to give the resistance tracks low friction, low tendency to stick/slip, resistance to abrasion and long-term stability. The rod is guided in a low-play floating frontal bearing. This absorbs small angular and parallel displacements. The guide lug and slide block have particularly tight tolerances, in order to ensure reliable slider contact. A ball joint coupling (see accessories) at the end of the sliding shaft minimizes axial errors between the sensor and the equipment. burster praezisionsmesstechnik gmbh & co kg Germany Talstr. 1-5 .
