Question

Explain the working principle of a linear variable differential transformer (lvdt). Show how it can be used for measuring small mechanical displacements.

Answer 1

LVDT – Construction and Working Principle. Linear Variable Differential Transformer, LVDT is the most used inductive transducer for translating linear motion into electrical signal. This transducer converts a mechanical displacement proportionally into electrical signal. The basic variable in LVDT selection is the maximum range of core motion, which produces an analog output of specific linearity. When the LVDT is used with the correct core for the specified frequency, the actual linear range will always equal or exceed the nominal value.
