Advantages of Inductive sensor | Disadvantages of Inductive sensor

This page covers advantages and disadvantages of Inductive sensor. It mentions Inductive sensor advantages and Inductive sensor disadvantages.

Definition of Inductive sensor:
It is one type of non-contact sensor works based on working priciple of a transformer. It is used for position and speed sensing. It uses coil or inductor for its construction. Hence the name inductive sensor.

Following two principles are used in a inductive sensor.
• Flow of fluctuating current through wire causes generation of magnetic field (H).
• Fluctuation of magnetic field around any conductive body causes current to flow in the body.


inductive sensor

Proximity sensor is one example of inductive sensor. It uses power supply which causes AC (Alternating Current) to flow in the coil. When conductive target comes near to the coil, impedance of the coil changes and this indicates that target is present. It is used to detect presence/absence of human beings as well as metal objects near to the sensor. The inductive sensor is also known as inductive proximity switch due to its two possible output states.

Inductive sensor is used for wide variety of applications viz. machine tools, to sense metal targets etc.

Advantages of Inductive sensor

Following are the advantages of Inductive sensor:
➨It can withstand harsh environmental conditions.
➨It has longer life.
➨It is very easy to install.
➨It has very predictable results and performance.
➨I has higher switching rate.

Disadvantages of Inductive sensor

Following are the disadvantages of Inductive sensor:
➨The sensing range of an inductive sensor dependents on the type of metal being detected, its shape, its size and also coil size used in the design. Due to above reason, inductive sensor has distance limitations for sensing.
➨It can detect metallic targets only.
