迟滞为6.61%FS

重复性误差为6.29%FS。

Abstract

Combine optical fiber Bragg grating（FBG） sensing technology

magnetoelectric effect principle of internal structure of DC generator and inverse piezoelectric effect of piezoelectric ceramic

develop an inverse piezoelectric FBG magnetic field sensors based on multi-coil magnetoelectric induction.The design uses multi-coil magnetoelectric induction

change of output current is getting smaller

sensitivity and accuracy of the inverse piezoelectric FBG sensors can be improved significantly.Repeatability test of forword and reverse stroke of magneticfield sensors is carried out

and comparative analysis on test data is carried out.Test results show that sensitivity of the magnetic field sensor is 0.112 8 pm / Gs

hysteresis is 6.61 % FS

repeatability error is 6.29 %FS.
