How Do Our Inductive Position Sensors Work?
Our inductive sensors are position sensors, or encoders, that acquires position measurement data through principles of induction – simply being the flow of current which induces a magnetic field. Working like resolvers, our inductive sensors feature compact conductive tracks that are excited at specific frequencies to generate an electromagnetic field. Fields generated by the rotor and stator that both contain these conductive tracks interact with one another like a transformer. This interaction can be measured to determine a highly precise angle measurement.
Inductive Sensors: FAQs
What does an inductive sensor sense?
An inductive sensor operates based on the priciple of electromagnetic induction. It senses position using coils on a printed circuit board (PCB) measuring a displacement relative to a target. The displacement is translated into a movement.
What are the differences between Magnetic and Inductive Angle Sensors?
A magnetic sensor detects a magnetic field directly, sensing permanent magnets as well as electromagnets, while inductive angle sensors detect a change in a magnetic field that the sensor generates. This makes them useful for sensing position and measuring change in position. Both types have their uses, but inductive sensors are mainly used in automation.
