Position sensors are integrated circuits (IC) which sense the movement or position of an object. They convert this measurement information into analog or digital output signals. Position sensors essentially take the information to/from a fixed position and provide feedback. There are different types of sensors for different requirements. A popular position sensor is an LVDT (linear variable differential transformer).
What do these sensors measure? Position sensors measure by a range of different methods such as: Rotation (Rotary) Angle Accuracy Distance
What is a linear position sensor? Linear position sensors are accurate sensors which measure the linear position of a device. Linearity is important for engineering applications. It measures the position of an object within a linear, straight line.
What is a rotary position sensor? Rotational position sensors detect the movement of an object's to give their angular position.
What is a resistive position sensor? Resistive position sensors use resistance to measure the position. This is a physical variable.
