The linear magnetic sensor is widely used in a high precision positioning system. In the installation of the linear magnetic system, any curved or uneven surfaces of the magnetic medium would result in significant fluctuations in the final recording accuracy during the position sensing process. This article investigates the effect of medium curvature on recording accuracy through experimental approaches. The results suggest that significant recording accuracy can be affected by the magnetic-flux density distribution over the medium caused by the medium curvature during installation. Through magneto-characteristic analysis, it also suggests that if the medium can be flattened, the recording accuracy can be improved.

安装误差对线性磁性介质磁特性的影响以提高记录精度

线性磁传感器广泛用于高精度定位系统。在线性磁系统的安装中，磁介质的任何弯曲或不平整的表面都会在位置感测过程中导致最终记录精度的显着波动。本文通过实验方法研究了介质曲率对记录精度的影响。结果表明，安装过程中介质曲率引起的介质上的磁通密度分布会影响显着的记录精度。通过磁特性分析还表明，如果介质可以平整，则可以提高记录精度。
