| Abstract: | The operating principle of fluxgate sensor with three tips was analyzed,and the mathematical model of the sensor structure was established.Such parameters and indexes in the model as sensitivity,permeability of the sensor were calculated.The optimum exciter wave-shape was determined by comparing the magnitude of sensitivity with different wave-shapes.The rationality of the mathematical model was validated using CAD,and the optimum exciter voltage and frequency were obtained in the condition of the maximum sensitivity. |
