介绍了一种精确、灵活的磁导率测量系统。特别是，通过利用主要系统特性，涡流和信号漂移等影响被最小化：（i）通过数字积分器进行高性能数字积分，理论分辨率为10 ppt，使用18位模数转换器，速度为800 kS/s，专门为磁测量而开发，以及（ii）测量过程的灵活性，用于通过借助于灵活的软件框架特别生成的过程来克服磁场非均匀性误差。特别是，理论背景下的测量，程序和系统架构的说明，以及从测试无取向钢的实验结果进行了描述。
An accurate and flexible system for magnetic permeability measurements is described. In particular, effects such as eddy currents and signal drift are minimized by exploiting the main system features: (i) high-performance digital integration by means of a digital integrator, with a theoretical resolution of 10 ppt using an 18-Bit A/D Converter at 800 kS/s, specifically developed for magnetic measurements, and (ii) flexibility of the measurement procedure for overcoming magnetic field non-uniformity errors through a procedure specifically generated by means of a flexible software framework. In particular, the theoretical background underlying the measurement, the procedure, and the system architecture are illustrated, as well as experimental results from testing a non-oriented steel are described.
