摘要
永磁体磁性能的稳定性直接影响电磁力平衡传感器的精度 ,其自动补偿具有重要意义。文中分析了永磁体磁性能的时间、温度、外磁场、腐蚀、冲击、振动等因素影响 ,介绍了改善电磁力平衡传感器永磁体性能、克服上述因素影响的老化方法与补偿方法 ,实际应用表明这些方法是切实可行的。
Magnetism of permanent magnet affects the accuracy of electromagnetic force balance sensor,and is important to compensate the effects of the magnetism. This paper analyses the factors producing variations of intensity of magnetization such as time, temperature, magnetic field, corrosion, shock and vibration,and introduces the ageing and compensation methods to overcome the effects of the magnetism of permanent magnet. Practical application shows that the ageing and compensation methods are feasible.
