Displacement Transducer

Position sensors are used to monitor and measure a change in position. this can be of an object, within a machine/ device or within a certain area/vicinity. There are several different kinds of position sensors available. One specific type of position sensor is a displacement transducer.

What is a Displacement Transducer?

A displacement transducer is a device used to convert the motion of an object or machine into electromagnetic, magnetoelectric, or electrostatic signals. These signals are read and interpreted into data.

Our Positek PIPS sensors are a type of displacement transducer, they can be linear for measuring linear displacement, or rotary for measuring rotary displacement.  

A displacement transducer is a reliable device with displacement measurement of various lengths or degree ranges, depending on the type of displacement being measured.

Our displacement sensors use our very own technology which makes them more reliable than other alternatives. PIPS is a non-contacting technology giving our sensors long life as they are free from wear.

 

What Are Displacement Transducers Used For?
 

A displacement transducer lends itself to various applications in the industry and even the public sector. Here are some application examples:

  • Machine automation. A hermetically sealed linear sensor performs well in extreme working conditions present in manufacturing factories, research and development laboratories, and industrial fabrication plants.
  • Aerospace and aircraft. Most aircraft related applications require using miniature displacement transducers. You can find sensors in satellites, drones, commercial aircraft, missiles, space vehicles, and flight simulators.
  • Power turbines. Power plants around the world use displacement transducer as position sensing device provided there are signal conditioners needed for operating power.
  • Hydraulics. Hydraulic accumulators need displacement transducers for sensing charge and as an external sensor for extreme environments exposed to shock and vibration.

Positek displacement transducers guarantee robustness and durability regardless of exposure to harsh working conditions.

Types of Displacement Transducers

There are various types of displacement transducer available which use different technologies. Some of these are;

Positek Sensors – our sensors are non-contacting and use a unique non-contacting technology – view our full range of displacement transducers on our website.

Potentiometers - A potentiometer can be either linear or rotary and uses a resistive track to measure displacement. This type of technology is known as “contacting” as the internal parts move against each other. Potentiometers are available from our sister company Variohm Eurosensor.

Capacitive sensor - A Capacitive sensor is a passive transducer requiring external power to operate. It is used to measure movement, pressure, and other parameters. These are available within the Variohm Group from Ixthus Instrumentation.

Resistive sensor - In this type of transducer, external or environmental factors result in variable resistance. A resistive transducer acts as a measuring device for displacement, temperature, and other physical quantities.

Hall-effect sensor - The working principle of a hall-effect sensor is converting the magnetic field into an electric measurable amount. Variohm Eurosensor have a wide range of rotary Hall effect sensors.
