Claims

[Scope of utility model registration request]

A liquid occupying approximately half of the space is sealed in a non-magnetic annular bobbin having an annular space, an annular magnetic core is housed with a required buoyancy on the surface of the liquid, and an excitation winding is applied around the outer circumference of the annular bobbin. The wire is wound, the excitation winding is further wrapped, and two wires perpendicular to the radial direction of the annular bobbin are wound.
In a buoyant magnetic direction sensing element in which two detection windings are wound so as to cross each other through the center of an annular bobbin, at least four detection windings are arranged along the length direction of the central axis on the side surface of the central axis provided inside the annular bobbin. A buoyant magnetic direction detecting element characterized in that the central axis groove described above is provided and at least one protrusion is provided on each of the upper and lower surfaces of the annular core case housing the annular magnetic core.
