<*n style="font-size:12px"><*n style="color:#000000"><*n style="font-family:微软雅黑,宋体,Arial,"Arial Narrow",HELVETICA"><*n style="background-color:#ffffff">YT-UQZ浮球液位计由磁浮球、传感器、变送器三部分组成。当磁浮球随液位变化，沿导管而上下浮动，浮球内的磁钢吸合传感器内相应位置上的干簧管，使传感器的总电阻(或电压)发生变化，再由变送器将变化后的电阻(或电压)信号转换成4～20mA的电流信号输出。并可在显示仪上设定上、下限报警，实现对液位的位式控制。

<*n style="font-size:12px"><*n style="color:#000000"><*n style="font-family:微软雅黑,宋体,Arial,"Arial Narrow",HELVETICA"><*n style="background-color:#ffffff">由液位传感器和智能HART板(电流转换器)两部分组成，浮球与液位同步变化，控制干簧管吸合断开，从而使传感器内电阻成线性变化，再由转换器将电阻的变化转换成4~20mA标准电流信号或叠加HART数字信号输出。
