What is Displacement?

Displacement is the movement of an object from one place to another. This can be in any direction.

As a position sensor specialist, displacement is something we regularly measure. Displacement is the movement of an object from one place to another. This can be in any direction.

Our sensors are used to measure linear displacement (movement along a single axis) or rotary displacement (movement in a circular motion).


Why Measure Displacement?


Displacement measuring is used to measure the exact distance something as travelled. Sometimes it is also used to check that something hasn't moved, or that something has successfully returned to its original place.

It is sometimes important to measure displacement to ensure the safety of personnel or to ensure machines and devices function correctly and effectively.

For example on an aeroplane, a displacement sensor will be used to monitor the level of the wing flaps, ensuring that they have moved to the correct position for take-off, landing and in flight. This ensures the plane functions correctly thus ensuring the safety of the passengers.

In MRI machines, a displacement sensor is used to ensure the patient is in the correct position and doesn't move during the examination. This ensures patient safety and ensures that the MRI machine can function correctly.

In bakery machines, a position sensor is used to ensure the device rolling the dough is in the correct position in relation to the belt so that the dough is rolled to the correct thickness.This ensures the machine functions correctly and that the products produced are to the correct standard.

These are just a few examples of displacement measurement, for more examples take a look at our blog post â€Position Sensor Applications"


Displacement Sensors


Displacement sensors are more commonly known as Position Sensors. Position sensors are our speciality here at Positek. They can be either linear or rotary, all of our position sensors are non-contacting and use our own PIPS technology.

Linear Position Sensors - linear position sensors are used to measure displacement in a linear fashion, along a single axis, either up and down or left to right. The technology which we use makes our sensors similar to LVDTs but they use only one coil and have a better length to measurement ratio. They are extremely robust and highly accurate.

Rotary Position Sensors - rotary position sensors measure displacement in a circular motion, twisting and turning. Our rotary position sensors are highly accurate and are non-contacting. They can measure angles from 5° up to 160°, they are well suited to high precision applications.


Position Sensors from Positek


All of our position sensors use our own position sensing technology, this makes them;

  • Hard wearing
  • Highly accurate
  • Unrivalled reliability
  • Suitable for harsh environments
  • Wear free offering longer life

We also offer a range of position sensors which are suitable for:

  • Intrinsically safe environments
  • Subsea environments


We have over 25 years experience in designing and manufacturing position sensors for a wide range of applications across many industries. All of our position sensors are manufactured in our onsite production facility and have customisable features. We can manufacturer sensors to custom specific applications and still offer delivery within 1-2 working days.
