无运动部件,频率和4至20毫安输出,免维护
MFS磁感应流量传感器是一种紧凑、低成本的桨轮传感器的替代品。与带有运动部件的传感器不同,MFS可用于处理污染介质的应用。该系列提供可靠的测量技术、无障碍管道横截面以及快速响应时间,使该系列成为无干扰操作的理想选择。液体的温度、密度、粘度、浓度或电导率的任何变化都不会影响磁感应式流量传感器的输出信号。除了使用寿命长外,这一系列产品非常适合于精确可逆测量封闭管道中导电液体的体积流量。
工作原理
测量管处于磁场中。如果具有一定流量的导电介质通过管道,它将以与磁场成直角的方向通过,从而产生一个与平均流速成比例的电压,并由MFS内的两个电极拾取。可获得与流量成比例的频率输出信号(可提供模拟输出选项)。
产品应用
导电液体流量监测导电液体喷洒器和废水处理的流量工业系统应用
特点
寿命周期长,无运动部件磨损或断裂处理流体中无机械部件的受污染介质的应用
无障碍管道横截面产生低压降
