摘要
本文综述了正弦信号激励的磁通门跑道型探头输出二次谐波电压灵敏度公式。从这个讨论出发,有可能寻找新探头工作物质。本文介绍选用非晶态合金代替玻莫合金绕制成磁通门磁强计探头,并对它进行直流、交流磁性能及电压输出灵敏度的测试。最后把这种材料与通常磁通门磁强计所采用的1J86玻莫合金进行分析对比。结果表明,非晶合金作为磁通门磁强计探头材料是大有希望的,且许多性能优越于玻莫合金。
The sensitivity of second_harmonic output of racetrackcore sensor driving by sine signal have been reviewed.From this discussion,we are able to look for some new sensor materials.In this paper,we studied a flu-xgate magnetometer sensor using amorphous alloy instead of Permalloy.The D.C.and A.C.magnetic properties,the voltage output sensitivity of this sensorhave been measured.At last we compared this material with 1J86 Permalloyused in normal fluxgate magnetometer.The result shows that amorphous alloyis a hopeful material as fluxgate magnetometer,some of its propertis are betterthan Permalloy's.
