| Abstract: | In view of the unmeasured disadvantage of the capacitive sensors under the liquid condition,because its sensitivity to the dielectric constant of a medium,a new sensor design project according to magnetic resistance was presented with magnetic grating structure,and the relative sensor was designed.Its circuit and mechanical architechture were introduced,and the integrating circuit was realized.It is demonstrated theoretically and experimentally that this kind of indicator possesses high sensitivity,resolution and good liquid resistant effect. |
