The Gems FS-930 series flow switches have a unique, patented piston design assures accuracy within 20% over a full range of viscosities—from 40 to 1000 SSU—making them ideal for use in applications where liquids of different viscosities are blended; or for use in lubrication systems where oil flow monitoring is critical at start-ups. The switch compensates for viscosity changes automatically. Each unit is factory preset, using 300 SSU oil, for actuation at specified flow rates.

The FS-930 series has a 1/4" NPT port for liquid flow settings from 0.10 to 1.00 GPM. Featuring rugged stainless steel bodies, the FS-930 utilizes a simple and reliable design suitable for operating temperatures from -20 to 300°F and line pressures up to 1000 psig. The Gems FS-930 uses a SPDT switch.

Applications for the Gems FS-930 Series flow switch:

  • 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 Purifications and Filtering, X-Ray Film Processing, Beverage Dispensing, Chemical Additives, Gas Sampling, Distilling
