Displacement Transducers

A Displacement Transducer can be described as an electromechanical device that is used to convert movement into a variable electrical current or electrical signal.

Displacement Transducer is another term used for position sensors. We have a wide range of displacement transducers including linear and rotary. This refers to the type of displacement they are designed to monitor.

Displacement Transducers are available in various technologies & housing types to fit different applications.

Displacement Transducer Technologies

At Variohm, we have a wide range of displacement transducers that use different technologies. The majority of these are non-contacting as these tend to have a longer life and are more reliable.

Some of the technologies we have available are;

Hall Effect – our hall effect sensors are rotary sensors. Many we manufacture as part of our own Euro-X range. This type of displacement sensor is often used for throttle control on vehicles as well as many other types of application.

As well as the standard Euro-X range we also have a micro range, as small as 10mm in diameter making them suitable for applications where space may be extremely limited.

Our hall effect displacement transducers have customisable options so contact us for more information.

Encoders – another sensor used for rotary displacement measurement is our range of encoders. Our encoder range includes both incremental and absolute encoders making them suitable for different types of applications.

Encoders are also available as shafted or hollow shafted depending on the application in hand.

Potentiometers – potentiometers can be suitable for measuring either linear or rotary displacement depending on the type. We have our own range of linear potentiometers which are available with signal conditioning or in miniature designs – very popular for Motorsport applications.

Potentiometers use a conductive track and a wiper to effectively measure displacement.

Inductive – there are various types of inductive sensor available on the market. We have a selection in our range, one of which comes from our sister company Positek who’s Inductive Position Sensors (PIPS), work similarly to an LVDT or RVDT but have fewer coils which make their stroke to length range better.

Inductive sensors can be used for measuring linear or rotary displacement depending on the type.

Cable Extension Transducers – cable extension transducers are for linear displacement only. Rather than using a solid shaft, they use a stainless-steel cable which is wound around a spool inside the transducer. The use of the cable means that they are suitable for long-range position measurement.

Cable extension transducers are available in various sizes with different approvals, view our range on our website.

Other Types of Displacement Transducer

Other types of displacement transducer technologies that have not been mentioned above include:

  • Eddy current
  • Ultrasonic
  • Laser sensors
  • Inclinometers
  • LVDT/RVDT

These types of technologies are not all available from Variohm Eurosensor, but they are available to purchase from within the Variohm Group from one of our sister companies. Contact us if your application requires one of the above.
