Metal Detection Using Inductive Sensors

Posted by Edwin Stoll on Thu, Sep 27, 2018

Inductive sensors are a type of proximity sensor that use an electromagnetic field to detect metal. The oscillating electromagnetic field generated by the inductive sensor drives eddy currents through a metal target. The eddy currents in the metal target generate an opposing electromagnetic field that resists the field being generated by the sensor. This causes a power drop in the sensor, indicating the nearby metal, and an output signal is given.
