There are three general classes of position sensors that – taken together – form a position sensing hierarchy. This hierarchy applies to any underlying sensing technology, for example inductive, capacitive, ultrasonic, or photoelectric. Going from the most basic to the most advanced sensor operation, the hierarchy includes:

The general sensing principle across this myriad of applications is nearly the same. As seen in last months post, the total amount of capacitance, as we remember, the ability to store a charge within an electrostatic field, depends on mainly three factors. Those factors are the ones which determine the success of your application.
