Their operating principle is based on a coil and oscillator that creates an electromagnetic field in the close surroundings of the sensing surface. Inductive proximity sensors are used for non-contact detection of metallic objects. Now let’s discuss the complete concepts of LVDT in detail. The inductive transducers work on the principle of the magnetic induction of magnetic material. The working principle of an inductive sensor mainly depends on the electromagnetic induction principle for detecting or measuring objects. An inductor develops a magnetic field when a current flows through it alternatively; a current will flow through a circuit containing an inductor when the magnetic field through it changes. The capacitive transducer works on the principle of variable capacitances. 9. Good stability, 4. This site is operated by KEYENCE CORPORATION. TransducerSensors.com. 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.
