Answer 1

Explanation:

LVDT (Linear Variable Differential Transformer):

LVDT (Linear Variable Differential Transformer) is to convert the rectangular movement of an object to the equivalent electrical signal.
LVDT is used to calculate displacement and works on the transformer principle.
The LVDT alters a linear dislocation from a mechanical position into a relative electrical signal including phase and amplitude of the information of direction and distance.
The working principle of the linear variable differential transformer or LVDT working theory is mutual induction; The dislocation is nonelectrical energy that is changed into electrical energy.
