磁通门磁强计感应回路的稳态解析模型
An Analytical Steady-State Model for FluxgateMagnetometer Detector Circuit
摘要
Abstract
An analytical model is developed to evaluate the influence of detector tuning capacitor effects on the sensitivity of fluxgate.The waveforms and the p-p value variation of the fluxgate output current are calculated with different tuning capacitances.The corresponding experiments are performed to measure the pick-up current in a uniform magnetic field.The correlation coefficients between the calculated and the measured waveforms are higher than 0.98,and the averaged deviation of the p-p value is less than 3%.The sensitivity varies 37% with the tuning capacitance changing within ±8%.This analytical model provides a useful tool for studying the properties of output of fluxgate efficiently and directly,and it also can be utilized for fluxgate temperature stability analyzing.关键词
