Working: A magnetic field develops when a current is flowing through the active inductive transducer then instantly the current flow by the circuit that contains an effective inductor when the magnetic field changes through it. The inductive transducers work on the principle of the magnetic induction of magnetic material. Inductive displacement sensors not only detect the presence of metal objects but also measure distances. The absolute inductive encoder, or inductive sensor, is based on the same electromagnetic induction principle as the resolver but uses PCB traces rather than coil windings.The TX track on the stator is excited by specific frequency in the range 1-10MHz. 2. The operating principle used may be resistive, inductive, capacitive , optoelectronic, piezo electric etc. The presence of a metallic object (actuator) in the operating area causes a dampening of the oscillation amplitude. Different principles have been applied to the model that detects metal only and to the model that can also detect non-ferrous metal.
