These rugged inline flow switches use 100-micron filtration and are less susceptible to clogging than other high-pressure inline flow switches. The one-piece magnetic PPS composite piston makes the FS-380 ideal for high-pressure applications such as industrial cleaning equipment. The Gems FS-380 is also an excellent choice for Semicon cooling applications where simple design and reliable operation are required.  

Gems also offer the FS-380B Compact Flow Switch, which features a unique dual connection port that provides 1/2˝ NPT and 1/4˝ push-to-connect fittings.

Applications:  

  • Electronic Equipment: Laser Heads, Welders, Power Supplies, High-Speed Spindles, X-Ray Tubes, Semiconductor Equipment 
  • Bearings or Gears: Presses, Rotating Equipment, Conveyors, Machine Tools, Robotics 
  • Processing & Dispensing Equipment: Water Purification and Filtering, X-Ray Film Processing, Beverage Dispensing, Chemical Additives, Gas Sampling, Distilling.
  • Flow Rate Settings: 0.25 GPM to 2.00 GPM 
  • Port Size: Multiple
  • Brass or Stainless Steel body
  • Setting Type: Fixed
  • Add to an Integratable Sensor Solution
