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.

安裝在任何位置
fsw-40a和fsw-50系列流量開關具有15a spdt開關和內(nèi)部螺釘調(diào)節(jié)功能，用于在線監(jiān)測開關點。多個牽引盤提供增量開關點調(diào)整。它們的非磁性設計使這些開關非常適合生銹的應用。fsw-40a系列采用黃銅和不銹鋼結(jié)構(gòu)（可選316不銹鋼），而fsw-50系列采用塑料/316不銹鋼結(jié)構(gòu)。
fsw-40a系列是理想的機器切削油和污水應用中，大型物體不被捕捉在拖盤上。對于2“及以下管道尺寸的開關，建議安裝“T”型管件。對于其他管道尺寸，可使用“三通”管件或焊接接頭。
