Potentiometric displacement transducers-8712, 8713

Linear displacements and mechanical values which can be converted to displacements (e.g. compressive and tensile force, strain, torque and vibration) may be measured by these DC/DC displacement sensors. The probe tip of these sensors is pushed onto the measuring object by a spring. This makes it possible to use these sensors were a mechanical modification of the measurement object (mounting hole) is not allowed or difficult. Output voltage as function of the displacement with the impedance as parameter. Sensors of series 87350 generally consist of an oscillator, a demodulator and a transformer with moveable core. They are energized by DC voltage. The oscillator uses this DC voltage to generate the carrier frequency, which is needed for the operation of the sensor. Dependent on the position of the core, which is made of ferromagnetic material, voltages are induced by the two secondary coils of the transformer.

Displacement sensors models 8710 and 8711 with resistance tracks made of conductive plastic material are designed for a direct and accurate measuring of mechanical displacements. A special ball joint coupling is mountable on both ends of the driving rod. Because of this the sensor may be used free of clearance or lateral forces also with angular or parallel misalignment between sensor and measuring device. A special multi-fingered slider provides a good electrical contact also at high adjustment speeds or vibrations. Areas of application are: —Electromagnets —Switch and button deflections —Pneumatic cylinders —Press-fits (longitudinal press-fits) —Hydraulic cylinders —Measurements of deformation and bending —Length tolerances —Feeding paths Due to the technology employed in potentiometric displacement sensors, they always operate with a sliding contact system.

Incremental magnetic measuring heads offer maximum precision over the full range of measurements. As a result of the magnetic operating principle and the robust mechanical construction, they are insensitive to soiling and are therefore ideally suited to use in production facilities. Thanks to the high quality of their measurements, their high protection and long service life, these sensors are used in many technologies (industry, research, development etc.). Typical applications include: —Monitoring both slow and fast movements between machine parts —Measurements of position and positional changes in components and structural foundations, of servo regulators, valve and robot controllers —Measurement of growth, and so on The incremental displacement sensors are based on a magnetic principle: consisting of a magnetic scale and a multi-slot reading head that responds to changes in magnetic flux, they detect linear movements with high precision and resolution.
