An Eddy current type displacement sensor can detect which types of objects? Correct Answer Metal Objects

Eddy current type displacement sensor can detect metal objects because it uses high frequency magnetic field for the detection of objects. When this metallic object come in the range of magnetic field, due to the electromagnetic induction, eddy current starts to flow through the object in vertical direction which causes a change in the impedance of the sensor. This change in impedance is used to measure the distance.
