FSW-50_51_52-HST流量开关OMEGA
Rugged Industrial Design
Switch Point Adjustable While Unit Is Operating
15 A SPDT Switch Directly Controls Pump
Mounts in Any Position
The FSW-40A and FSW-50 Series flow switches feature 15 A SPDT switches and an internal screw adjustment for in-line monitoring of switch points. Multiple drag disks provide incremental switch point adjustment. Their non-magnetic design makes these switches ideal for applications in which rust is a problem. The FSW-40A Series has a brass and stainless steel construction (optional 316 SS), while the FSW-50 Series comes in a plastic/316 SS construction.
The FSW-40A Series is ideal for machine-cutting oils and for sewage applications in which large objects are not caught on the drag disks. Installation “T” fittings are recommended for installing switches for 2" pipe size and below. For other pipe sizes, a “tee” fitting or weld coupling can be used.

安装在任何位置
fsw-40a和fsw-50系列流量开关具有15a spdt开关和内部螺钉调节功能，用于在线监测开关点。多个牵引盘提供增量开关点调整。它们的非磁性设计使这些开关非常适合生锈的应用。fsw-40a系列采用黄铜和不锈钢结构（可选316不锈钢），而fsw-50系列采用塑料/316不锈钢结构。
fsw-40a系列是理想的机器切削油和污水应用中，大型物体不被捕捉在拖盘上。对于2“及以下管道尺寸的开关，建议安装“T”型管件。对于其他管道尺寸，可使用“三通”管件或焊接接头。
