A displacement sensor or displacment gauge (3) for detecting misalignment measures the dislocation of a machine part, such as a post (12), by means of four magnetic coils (24N, etc.) deployed 90°apart around the post and each energized by an oscillator (36N, etc.). A reference position of the machine part (12) relative to another component (6) of the machine is first established. Subsequent displacement is detected and excessive displacement is indicated if it exceeds a predetermined threshold magnitude. Signals from the four coils are processed combined in such a way that the magnitude of the radius of a displacement of the machine part (12) from the reference position is ascertained and provided irrespective of the direction of the displacement. The provided signal equals the greatest of the absolute values of (a) a north/south displacement signal, (b) and east/west displacement signal, and (c) one or more combination signals that are derived from the north/south and east/west absolute value signals, and that represent the displacement in various intermediate directions e.g., east by northeast.

A displacement gauge (3) for sensing displacement of an object (12), comprising: a plurality of proximity sensing means (24N & 37N, 24E & 37E, etc) positioned at angularly-spaced-apart directions from said object, for producing a set of primary direction signals (from 45, 54), each dependent upon th
A displacement gauge (3) for sensing displacement of an object (12), comprising: a plurality of proximity sensing means (24N & 37N, 24E & 37E, etc) positioned at angularly-spaced-apart directions from said object, for producing a set of primary direction signals (from 45, 54), each dependent upon the vector component of the object\s displacement along a respective directional line (e.g. N-S, E-W); means (48, 57) receiving said set of primary direction signals, for converting them, in the event that the signals are not all of the same sign originally, to a second set of direction signals (at 48T, 57T) that are all of the same sign; addition means (FIG. 6, 62a62b, 51a) that scalarly add at least two of the direction signals of said second set, with predetermined appropriate weighting factors, for providing at least one composite direction signal (at 51T); whereby a first-order array of signals (at 59, 61, 62) is provided, comprising both said second set of direction signals (at 61, 62) and said composite signal (at 59), each signal of said first-order array indicating the magnitude of the object's displacement along a respective directional line.
