The Gems FS-926 series flow switches are precision-calibrated to provide 1% repeatability for low flow applications. Boasting reliable and consistent performance, the FS-926 provides accurate detection of excessive or insufficient flow rates in such applications as: protecting against loss of fluid flow in hydraulic systems, assuring proper coolant flow in semiconductor processing equipment, monitoring high pressure lubrication systems, and ensuring proper air flow in water/waste systems. These switches are also ideal for applications such as gas sampling, liquid or gas leak detection, or chemical injection.

The FS-926 series has a 1/4" NPT port for liquid flow settings from 50 to 300 cc/Min (0.013 to 0.075 GPM ) or air/gas flow rates from 2 to 50 SCFH. Featuring rugged brass or stainless steel bodies, the FS-926 utilizes a simple and reliable design suitable for operating temperatures from -20 to 300°F and line pressures up to 1000 psig.

Applications for the Gems FS-926 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
