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 driving rods are guided in long-life, low-friction sliding bearings with close tolerances; this results in highly precise measurements. Transverse forces reduce the service life and can be avoided by using, for instance, ball joint couplings. Due to the pimp effect, the driving rod has double sliding bearings. All the figures quoted in the data sheet for non-linearity, service life, reproducibility and temperature coefficient apply to the use of the sensor as a voltage divider with a maximum current of 0.1uA.
A ball joint coupling (see accessories) at the end of the sliding shaft minimizes axial errors between the sensor and the equipment.

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 12.9 mm, the model 8709 is also suitable for highly compact structures.
The movable fastening clamps allow the user tvariable 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
