Liquid floating type double-shaft fluxgate sensor

The utility model provides a liquid floating type double-shaft fluxgate sensor, and relates to the technical field of sensors. A sensor inner shell is arranged in a sensor outer shell and is connectedwith the sensor outer shell; a center support is arranged in the sensor inner shell, suspension liquid is arranged between the sensor inner shell and the center support, the center support is sleevedwith the concentric ring, a protruding structure is arranged on the concentric ring, a limiting groove is formed in the balance ring, the concentric ring is sleeved with the balance ring, and the middle of the protruding structure is arranged in the limiting groove. The balance ring and the concentric ring form a limit connection structure, the balance ring and the concentric ring are ensured tohave spherical connection of plus or minus 35 degrees through the suspension liquid, and meanwhile, the concentric ring ensures that the balance ring does not rotate on the horizontal plane under theaction of the limit groove o
