挡片式流量开关
FB31系列
原理,结构                                                                              
机械式流量开关。内置弹簧支撑的档片,当流量达到预制值时,机械结构触发微动触发开关。                                                                         
特点                                                                                   
在线式安装,极小的压力损失,良好的重复性,抗污能力,通过旋钮实现精确的开关设定。机械部分与电子部分安全隔离。                                                                                                                                                                       
应用                                                                                   
气液两用型,工业自动化/ 机械设备/ 空气压缩工业/ 制冷及空调      适用于直径≤50mm的管道。
