In the past, the operation of the differential transformer has been analyzed based on the change of the in the magnetic reluctance of air gap caused by the magnetic core displacement. However, this method of analysis does not fully take in account the properties of core materials and the effect of leakage fluxes. Moreover, the quantitative relation between circuit parameters cannot be made clear. Previously, one of the authors has believed that the phenomena can essentially be clarified only by dealing directly with the magnetic flux itself on the core axis, and already applied this idea to analyze a two-sectional type differential transformer. In this paper, we wish the extend this idea to derive an theoretical equation for the output voltage of the three-sectional type differential transformer taking into account the demagnetization of magnetic core and the flux distribution along the core axis. The equation of the magnetic flux distribution (P(X) is given by \u03a6(X) = \u03a6\u2080cos\u00b2(\u221a2C 2X/lc)e\u207b\u03b3\u00b2C 2X/lc, X\u22650, (1) where X is the distance measured from the center of the magnetic core along its axis. When the load resistance of secondary winding is infinitely large, the theoretical expression for the output voltage E\u2082 (effective value) is obtained by E\u2082=\u03c9N\u2082(\u03a6\u2082b-\u03a6\u2082a)=\u03c9N\u2082\u03a6\u2080 \u03bce-\u03bbl\u2081/2\u03bc / \u03bb\uff4cl\u2082 (P cos 2x/\u03bc sinh \u03bbx/\u03bc - Q sin 2x-\u03bc cosh \u03bbx/\u03bc - R sinh \u03bbx/\u03bc)), (2) where P, Q and R are coefficients which do not depend on the linear displacement, x, as follows : P = \u03bb/\u221a4+\u03bb\u00b2{e \u03bb(l\u2081-lm)/2\u03bc sin(lm/\u03bc+\u03c6) + sin(l\u2081/\u03bc + \u03c6)}, Q = \u03bb/\u221a4+\u03bb\u00b2{e \u03bb(l\u2081-lm)/\u03bc cos(lm/\u03bc+\u03c6) + cos(l\u2081/\u03bc + \u03c6)}, R = e \u03bb(l\u2081-lm)/2\u03bc + 1.
