KSR液位开关 科普乐浮球液位控制器 KSR代理

KSR浮球液位开关有一个带永磁体的浮球,该浮球能够可靠地随着液位的变化在导向管中上下运动。导向管内装有一个磁干簧触点(填充惰性气体)。当浮球接近时,永磁体产生的磁力会透过浮球的无磁性壁和导向管,使触点发生吸合。通过使用磁体和磁干簧触点可以实现非接触式开关动作,从而可避免产生磨损,且无需使用电源。该浮球开关可进行多个开关点测量。
开关状态总是随着液位变动而进行切换:常开型 (S) /常闭型 (O) /转换型(U)触点。
通过使用一个浮球就能实现对2个双稳态开关点的操作,即当液位超过或低于开关点位置时,液位开关能够保持原来的开关状态。
浮球液位开关安装简单且无需维护,因此安装、调试和运行成本都很低。
