Draw and describe the constructional diagram of LVDT.
Construction of LVDT:
A differential transducer consists of a primary winding and two secondary winding.
The windings are arranged concentrically and next to each other. They are wound over a narrow bobbin which is usually of a non- magnetic and insulating material.
A core in the shape of road is attached to the transducer sensing a shaft.
An AC source is applied across the primary winding and core varies the coupling
between it and two secondary windings.
