矿热炉磁场阵列传感器测试用三维磁场源的产生与检测系统

iming at the problems of performance assessment of magnetic field array sensor for detecting the key parameters of submerged arc furnace, a three dimensional magnetic field generation and measurement system is designed. A 3D Helmholtz coil is developed to supply magnetic field signal, and microcontroller collects the magnetic field data and send them to the upper computer. In the environment of LabVIEW the magnetic field information could be processed and displayed. At the same time, the scanning trace of 3D magnetic field probe is controlled by three dimensional guide rail, and the probe position and scanning status is observed simultaneously in PC. The system plays an important part in the small scale production and detection of magnetic field array sensor.
