The invention discloses an inductive plumb coordinator, which is characterized by comprising an inductor fixed on a plumb body. The inductor has a hollowly cylindrical insular carrier and a magnetic material fixed with the same; the magnetic material is uniformly distributed around the central line of the hollowly cylindrical insular carrier; the inductor is sleeved outside the plumb body; the two sides in X direction and the two sides in Y direction of the inductor are provided with a pair of coils respectively; the coils on the two sides in X direction of the inductor are connected with a signal converter in X direction, while the coils on two sides of Y direction are connected to a signal converter in Y direction. The inductive plumb coordinator of the invention has the advantages of ingenious design, high measuring precision and relatively strong resistance to environmental interference; the inductive plumb coordinator is suitable for various severe environments and particularly is capable of reliably monitoring the dam displacement for a long time in humid, water-dropping and dusty environments and the like. The inductive plumb coordinator is expected to be popular and have agood market prospect after being launched.
