PTFE( 聚四氟乙烯)/15％石墨
轻质塑料设计使之可以安装在任何位置
产品介绍
GEMS FT-110低流量传感器工作时是当流体沿着管道的轴线方向流动,并冲击涡轮叶片时,便有与流量qv 、流速V和流体密度ρ乘积成比例的力作用在叶片上,推动涡轮旋 转。在低流量传感器叶片周期性地切割电磁铁产生的磁力线,改变线圈的磁通量,振荡器振荡及停振的变化被后级放大电路处理并转换成脉冲信号。此脉冲信号的频率与被测流体的流量成正比。
Gems 的霍尔效应透平流量传感器对于低流量液体监测的OEM 应用十分理想. 低廉的价格，加上0.5% 的重复性，使FT-210成为分配计时器系统的理想替代品. 与现有的计时系统不同的是，透平技术不受系统压力变化的影响. FT-210低流量传感器的标准电源和输出规格使之易于改进，以适应当前的控制器.
