摘要
国内在磁场时域测量方面侧重于单频磁场的测量,宽频磁场三维时域波形的测量研究少见报道。在三维磁阻传感器HMC1053的基础上,研制了一种适用于低频磁场的测量装置,可以直接读取空间宽频磁场的三维时域波形,并且设计了适用于HMC1053的置位/复位电路,提高了仪器的可靠性和准确度。最后对通电长直导线周围的磁场进行实验测量,给出了数据和图形。
Study of magnetic field measurement in time domain in China is particularly focused on the single frequency. There are few reports about measurement of magnetic field on broad band three-dimensional in time domain. This paper introduces the design of a magnetic field measurement apparatus based on HMC1053 technology which was applied to the test of low frequency magnetic field. The apparatus can directly display three-dimensional wave of the space magnetic field in time domain. The design of the set/reset circuit for the three-dimensional sensor improves the reliability and the accuracy. Experimental data and graphics were obtained by measuring the magnetic field around a live wire.
