FS-925 Series General-Purpose Flow Switch
Brand: Gems Sensors, Inc
The FS-925 Series of precision-calibrated switches provides reliable and consistent performance; repeatability is within 1%. FS-925 units are factory preset for actuation at specified flow rates.
These switches provide 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
Features- Flow Rate Settings:
- Liquids: 0.1 GPM to 1.5 GPM
- Air/Gases: See Flow Settings at right
