When temperatures of viscous fluids change, so do their flow properties. With viscosity lowered by increasing temperature, a greater flow is generally required to create actuation pressure differential. A unique patented piston with Gems Sensors FS-930 Series switches accommodates these changes in fluid viscosity while maintaining accurate switch actuation. Units can detect flow rates with 20% accuracy for fluid viscosities between 40 to 1000 SSU.
FS-930 Series Flow Switches have a unique, patented piston design that assures accuracy within 20% over a full range of viscosities - from 40 to 1000 SSU. Ideal for use in applications where liquids of different viscosities are blended or for use...
FS-925 Series Flow Switches provide accurate detection of excessive or insufficient flow rates in a range of applications including protecting against loss of fluid flow in hydraulic systems, assuring proper coolant flow in semiconductor...
FS-927 Series Flow Switches are compact switches that measure only 1" x 2-3/4" (25 mm-70 mm) and are ideal for use where space is at a premium. Designed for use with water and oil, these switches are suitable for high volume OEM applications. They...
