The measurement principle of resonance frequency of magneto-elastic sensor is analyzed.The influence of DC-bias magnetic field change on measurement of resonance frequency is analyzed
the relationship between sensor size and optimal DC-bias magnetic field is proposed.The experiment shows the influence of ΔE effect on measurement accuracy of resonance frequency of sensor.
