When core of LVDT is moved to the left of the NULL position ‘O’ as shown in figure above, the flux linkage of secondary winding S 1 will become more than that of winding S 2.This means the emf induced in winding S 1 will be more than S 2.Hence E s1 > E s2 and net output voltage E 0 = (E s1 – E s2) = Positive.This means that the output voltage E0 will be in phase with the primary voltage. A typical application of a linear variable differential transformer (LVDT) sensor would be as a pressure transducer, were the pressure being measured pushes against a diaphragm to produce a force. analog This is the most useful mutual inductance transducer which provides an a.c. voltage output proportional to the displacement of a core passing through the windings.
