BTY-G系列光纤液位变送器利用力学自平衡原理实现液位或界面的检测。变送器由测量单元(包括浮子、计量钢丝绳、重锤、主动轮、过渡轮等)、光码变送器、光缆等部分组成。当被测介质液位发生变化时,浮子随液位升降产生位移,通过计量钢丝绳、主动轮、过渡轮将该直线位移转变为角位移,再通过磁耦合, BTY-G series fiber optic liquid level transmitter using the principle of self-balancing mechanics to achieve the level or interface detection. Transmitter by the measuring unit (including the float, measuring rope, hammer, driving wheel, transition wheel, etc.), optical code transmitter, cable and other components. When the level of the measured medium changes, the float displaces with the rise and fall of the liquid level, and the linear displacement is transformed into angular displacement through the measuring rope, the driving wheel and the transition wheel, and then, through the magnetic coupling,
