Relations between the signal - to - noise , sensibility , demagnetizing factor , output of fluxgate sensor with its diameter , thickness and turns of core are discussed in this paper . the author of this paper also concluded some basic principle for the designing of fluxgate sensor . the author designed and produced two dimension sensors to prove the possibility of the miniaturization of fluxgate sensor 本文還分析了小型化傳感器的實現(xiàn)可行性,分析了磁通門傳感器的信噪比、靈敏度、退磁系數(shù)、感應輸出與傳感器磁芯直徑、厚度和磁芯匝數(shù)的關系,論證了傳感器小型化的可行性,總結(jié)了在設計磁通門傳感器時所應遵循的基本原則,并且設計制作了兩種尺寸的傳感器,從實驗角度論證了傳感器小型化的可行性。
