摘要
对不同种类的磁芯材料性能进行实验研究,结果表明高B_r/B_s超微晶的磁芯较适合作零磁通检测器的探头材料,这种材料检测灵敏度高,对调制频率及调制幅度变化的影响小,常温下几乎不受温度变化的影响,且在市场上容易得到。另外,高μ铁氧体也可能适合作零磁通检测器的探头材料。
A variety of magnetic cores were examined. It shows that the super microcrystalline iron core with high Br/Bs is more suitable to make a zero-flux sensor head, as high sensibility and great stability can be achieved for the zero-flux sensor made with this magnetic material. In addition, the ferrite core with high permeability seems to be another acceptable material to make a zero-flux sensor head.
