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 are able to 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 cats claw configuration that ensures the best wiper contact for applications even in the most severe of environments. Linear potentiometers can be used in many applications which require a robust device for measuring linear movements.
This means that if the knob of the potentiometer is at the medium position, the output voltage is half of the voltage through the potentiometer.
See the figure below:. Non-linear tapers are specially used in audio control applications, namely logarithmic tapers there are also inverse-logarithmic tapers.
The relationship between the position and the resistance is shown in the following figure:. Arduino Step-by-Step Projects » Build 25 Arduino projects with our course, even with no prior experience! Very nice article and full of great information. Thank you so much! I wish more information on the Web was well presented like this.
