Linear resistive sensor

A linear resistive sensor, also known as a linear potentiometer, is a device that measures linear displacement by varying the resistance in a resistive element. It is an economical and widely used solution in applications where the position or displacement of an object needs to be measured in a limited range.

The linear potentiometer consists of a resistive track on which a slider or brush moves. As the slider moves along the track, it modifies the effective length of the resistance between the terminals of the device. This change in resistance is proportional to the linear displacement of the slider, allowing an electrical signal to be obtained related to the position.
