Inductance type water pressure sensor

The invention belongs to the technical field of sensors, and particularly relates to an inductance type water pressure sensor which comprises a base, a base body, a coil and a magnetic core. A first hole is formed in the center of the base, an annular first groove is formed in the bottom of the base with the first hole as the circle center, and a set of arc-shaped T-shaped grooves are evenly formed in the first groove; sliding blocks are arranged in the T-shaped grooves in a sleeving manner; and by arranging the protruding blocks, the base body continuously enters the mounting hole through the arc-shaped plate, the surface of the pipeline rubs with the protruding blocks to make the protruding blocks move, the protruding blocks move to drive the rotating shaft to move till the rotating shaft makes contact with the pipeline, the protruding blocks are located on the two sides of the pipeline at the moment, the base body is mounted at the top of the base through bolts, and the first block slides into the second h
