What Is A Linear Potentiometer?

A linear potentiometer is a type of position sensor. They are used to measure displacement along a single axis, either up and down or left and right. 

Linear potentiometers are often rod actuated and connected to an internal slider or wiper carrier. The rod will be connected to a device or object which requires measurement. The linear potentiometer proportionally divides an applied regulated voltage over its operational range and provides a proportional voltage output relevant to the position of the wiper.

Linear potentiometers are a contacting type of sensor which means that the moving parts make contact with each other during use. This makes them sufficiently robust to be used within a variety of applications whilst remaining relatively inexpensive. They can function in wide temperature ranges and offer long life, high accuracy and repeatability. 

At Variohm, our range of linear potentiometers uses a conductive plastic technology which is the most widely used. We use elastomer damped wipers which means they have a cat claw configuration that ensures the best wiper contact for applications even in the most severe of environments. 

What Is A Linear Potentiometer Used For?

Linear potentiometers can be used in many applications which require a robust device for measuring linear movements. Some examples of these applications are;
  • Mobile Vehicle
  • Medical applications
  • Industrial process
  • Test and lab applications

  • Q What is Potentiometer?


    A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.[1] If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

    The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name.

    Potentiometers are commonly used to control electrical devices such as volume controls on audio equipment. It is also used in speed control of fans. Potentiometers operated by a mechanism can be used as position transducers, for example, in a joystick. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load.
