Types of Electrical Sensors
The different types of electrical sensors are resistive, capacitive, inductive, and magnetic. Resistive is the most common type of sensor in use today. It consists of a wire that changes its resistance when pressure is applied to it. Capacitive sensors measure how much energy has been stored by the system. Inductive sensors work by measuring voltage induced into an adjacent loop or coil as a result of changing magnetic flux linked to it from another magnetically-held device called an inductor, which produces a current in the coil when moved relative to it. Magnetic sensors detect where metal objects are located near them through magnetism – this includes ferrous metals like steel and non-ferrous metals like aluminum or copper alloys.
