Data Sheet Model 8718 - 1

Potentiometric Displacement code: Sensor Delivery: Application The high resolution allows linear measurements to be accurately sized even in large measurement ranges. Conversion of rotatory and translational motion by spindles, wires or others is not necessary for direct displacement measurement. Areas of application are: ► Hydraulic and pneumatic cylinders ► Detection of positions on coordinate inspection machines ► Displacement of plungers, knee levers or extruders ► Coil and de coil lengths ► Strokes on chassis ► Metering strokes ■ Measurement ranges from 0 ... 100 mm to 0 ... 2000 mm ■ Non-linearity up to 0.05 % F.S. ■ Compact design, without rod ■ Displacement speed up to 10 m/s ■ Durability >108 operations Description Displacement sensors model 8718, using a resistance track made of conductive plastic material, are suitable for direct, accurate and absolute measurements of displacements and lengths. Special processes are applied to give the resistance tracks low friction, low tendency to stick/slip, resistance to abrasion and long-term stability. The vibration-cushioned slider allows a clear signal output even by slight shocks or high operating speeds up to 10 m/s. Due to its simple design the sensor is largely protected against electrical interference fields (Al-housing), it keeps the measured value after a power failure and does not generate any electrical interference. A magnetically hold steel band covers the whole measurement device gap free. Any lateral forces are avoided by a ball joint coupling mounted to the sensor. Technical changes reserved.
