Baffle flow switch(Paddle flow switch)
FS-FB11 series Baffle flow switch , also known as Paddle flow switch and flow switch .There are 5 types mechanical baffle .Suitable for the pipe diameter DN25-DN150 , the set range is 20-1800L/min (water) .It is mechanical switch output (250VAC,3A) . Suit for several kinds of medium and with high reliable .
Application:
Used for gas and liquid . Suitable for industrial automation / mechanical equipment/compressed air industry /refrigeration and air conditioning . Suitable for the diameter >=25mm .
Principle:
Baffle type flow switch is one kind of mechanical flow switch , also known as paddle flow switch .When the medium rushing at the vane ,the vane will swing .It will change the relative position of the magnet and reed contactor .Further ,stimulate contactor and make it close or open .Once the medium was broken ,the vane will back to the original position. Stimulate the reed contactor again ,the repellency of two magnets will provide power which can reset the flow switch .At the time ,the contactor will back to the previous state . It is with built-in micro-trigger switch .
Features:
-With extremely small pressure loss
-Good repeatability
-With high anti-stain ability
-Accurate switch setup through knob
-The mechanical part isolate with electric part totally .
-It will provide 5 kinds of baffle. When small flow rate in big diameter pipe or the pipe is not fulfill it , user can change it according to the field situation . Also , it make one type flow switch to suit for different size pipe .
