FS-926 Series Flow Switch
Quick Specs...
Overview / Design Principle:
This series of precision-calibrated switches provides reliable and consistent performance; repeatability is within 1%. FS-926 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. The FS-926 Series, designed for liquids or gases, features a special low-flow piston. This additional piston allows the detection of fluid flow as low as 50 cc/min. These switches are ideal for applications such as gas sampling, liquid or gas lead detection, or chemical injection.
