摘要
目前水位检测在产品上的多为干簧管类,应用成熟但需要有导线引入到开关上;磁控类开关通过磁场感应导线不与水接触,安全可靠性高,但产品应用不成熟,大多靠测试定义产品性能,由于磁控可有效利用距离小,容易出现问题。鉴于磁控开关在水位检测上突出的优势,本文根据磁控开关的工作原理,建立浮子永磁体模型,通过仿真得到永磁体磁场空间分布,结合霍尔电气性能,匹配合适的磁控开关有效控制距离;再通过磁控开关实际应用测试,定义开关的有效行程,从而实现磁控开关的有效应用。该研究为此类磁控开关的应用有指导意义。
At present,the most of the water level detection products are reed tubes,which are mature in application but need a wire to be introduced into the switch.The wire does not contact with water through magnetic field induction in magnetron switch application,high safety and reliability,but the product application is not mature,mostly rely on testing to define product performance,because the effective use of magnetron distance is small,prone to problems.In view of the outstanding advantages of the magnetron switch in water level detection,this paper establishes the floating permanent magnet model according to the working principle of the magnetron switch,and obtains the magnetic field spatial distribution of the permanent magnet through simulation.Combined with the Hall electrical performance,the appropriatemagnetronswitch caneffectively controlthedistance.Thentheeffectivetraveloftheswitch isdefined bythe actual application test of the switch,so as to realize the effective application of the switch.This research has a guiding significance for the application of the kind of the magnetic switch.
