Potentiometric displacement sensors are used for direct, precise measurement of mechanical displacements. The mechanical parts of the measuring equipment must be set-up in such a way that the sliding shaft can move without play or lateral forces. A special multi-finger slider ensures good contact even when the adjustment speed is high or in the presence of vibration. With its housing diameter of only 12.7 mm, the model 8709 is also suitable for highly compact structures. The movable fastening clamps allow the user variable options for attaching the sensor without complication. Optionally available adaptations, such as flange and ball joint versions, extend and complement the range of possible applications. Typical fields of application include: Measuring the stroke on riveting machines Measuring insertion distances Offset measurements on bearings Spring travel measurements on axes Measurements of the movement of hoisting platforms Length measurements on pipe bending machines

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. Application fields include: —Electromagnets —Deformations - bending —Pneumatic cylinders —Length tolerances —Press-insertions (longitudinal press-fits) —Feed strokes —Machine hubs —Punch, knee lever or extruder distances —Hydraulic cylinders 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 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 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.

As an angle sensor that is both accurate and economical, this rotary potentiometer is suitable for all types of analog angle measurement up to 350°. Typical fields of application include: —Position feedback in servo-systems —Pendulum weighing machines —Cam and butterfly flap positions —Jockey roller controllers —Measuring the tension of threads and tape —Trigonometric measurements at joints The heart of the potentiometric angular displacement sensors is an extremely precise, low-wear resistor track made of plastic. Due to its high resistance to abrasion, the sensors are particularly suitable for measurements for the purpose of quality assurance in ongoing production, where a long service life and large numbers of rotations are required. The potentiometric angular displacement sensor uses a multi-finger slider system with precious metal contacts. This ensures good contact even when moving at high speed and in the presence of vibrations.
