ZHOU Deqiang, WANG Hua, CHEN Dewen, et al. Analysis on influence of magnetoelastic membrane position change on detecting signal[J]. 2020, (3): 10-13. DOI: 10.13873/J.1000-9787(2020)03-0010-04.
As the position of the magnetoelastic ribbon relative to the coil has a certain influence on the detecting result
different positions of the magnetoelastic ribbon in the coil are experimentally studied. The experimental results show that the resonant frequency of the magnetoelastic ribbon in the middle of the coil is significantly smaller than the resonant frequency of the magnetoelastic ribbon at the ends of the coil
and the difference of the resonant frequency can reach 0. 9 kHz
which means the positon have a significant effect on the detecting result.The resonance frequency shift caused by mass has a linear relationship with the fundamental frequency of the sensor. Therefore
