非正弦波中频强磁场测量方法及装置
On the Measurement Method and Device for Non-Sinusoidal Wave Medium Frequency High Magnetic Field
摘要
Abstract
With Hall element A1323LUA as the magnetic signal converter, and AD637 as the true RMS integrated converter, a Hall sensor measuring circuit and signal processing circuit was firstly constructed;Then, in combination with other function modules, and by adopting true RMS instead of average algorithm, a measurement device was produced in the lab to measure magnetic fields with different current waveform.The calibration and measurement verification of magnetic induction intensity meter shows that it can meet the test need of the non-sinusoidal wave medium frequency high magnetic field.关键词
