Mathematical Modelling of GMI Sensor with Double-core Structure
In this paper, the mathematical model of the GMI sensor with double-core structure is deduced.By analyzing the structure and the mathematical model of single-core GMI sensor, the drawback caused by bias current drift or temperature drift is found.According to the double-peak feature of the amorphous, GMI sensor with the double-core structure is given and the mathematical model of this sensor is developed, which can effectively improve the bias current stability and the temperature stability.Finally, the results are confirmed by experiments.
