These
displacement sensors are used for direct measurement,
testing and monitoring of mechanical displacements. The
spring-loaded control rod at model 8712 eliminates the
need coupling with the measurement object.
A prerequisite for a very long life duration of the
devices is a parallel alignment of the direction of
motion of the measurement object with the control rod.
Areas of
application are:
| • |
Displacement
on |
electromagnets,
hydraulic cylinders,
switches and buttons. |
| • |
Measurements
of |
deformation,
bending,
indentation. |

| Description |
 |
Based on
their technology, potentiometric displacement sensors
consistently make use of sliding components. The
resistance track is trimmed in special process to
minimize friction and stick-slip for long stability and
measuring quality.
The double supported rod is equipped with durable,
low-friction, narrow-tolerance plain bearings which
ensure a long service life and high measuring accuracy
too.
Model 8710 is designed without spring. Mechanical
linkage using joint with take up of play, M4 thread.
At model 8712 a pre-stressed spring presses sensor tip
against the measurement object. Tip with M 2.5 thread
and stainless steel ball. The bore at rod end serves for
coupling retraction units.
The stainless steel pallet is recessed into the sensor
tip. The bore in the connecting rod stop at the rear
serves for coupling retraction units.
