磁传感器温度特性校准装置研究

摘要

In this article,describe the system composition,working principle and specific design principle of main parts of the temperature property calibration device for temperature property of magnetic sensors formed by adding magnetic coils outside the non-magnetic high-low temperature tester.Introduce the realization method for “nonmagnetization” in detail.Hereby,it is realized to reproduce stationary magnetic filed of 0～100 μT in the temperature range of-60℃～150℃,which can be used to calibrate the temperature properties of all kinds of weak magnetic sensors in this range.%叙述了在无磁高低温试验箱外加磁场线圈的形式组成磁传感器温度特性校准装置的系统组成、工作原理及主要部分的详细设计原理等,并详细介绍了“无磁化”的实现途径.利用该方法实现了-60℃～150℃温度范围内复现0～100 μT恒定磁场,可以用于校准该范围内各种弱磁传感器的温度特性.
