Abstract :
A proposed new three-tip fluxgate sensor is developed that is structured of a racetrack loop iron core and a couple of symmetric inverse-parallel windings. The second harmonic of the output signal is twice proportional to the measured external magnetic field intensity. The magnetic measuring resolution reaches 1nT, and the dynamic measuring range reaches 100μT. The multi-channel magnetic measuring system, which is made up of three-component and three-tip fluxgate sensors, can satisfy the requirement of the space magnetic measuring on large warship.
