Abstract
A displacement measuring device for detecting a relative position of an object by interposing the object between a set of at least two displacement sensors. The displacement sensor may comprise of a core body that includes a detection coil and a pair of excitation coils. The sensor may produce a differential output based on the balance of the magnetic flux between the excitation coils with satisfactory linearity and/or higher sensitivity, in which the impedance due to the DC resistance component or the like is removed.
