FS-500 – Series Flow Switch

FS-500 – Series Flow Switch The FS-500 offers low cost flow monitoring with a variety of switch actuation points and low pressure drop. All wetted parts are polypropylene or stainless steel, making this flow switch ideal for a wide range of chemical and temperature requirements. The materials are also NSF or FDA approved for potable water treatment applications including chlorinators, purifiers and heaters. The FS-500 is ideal for equipment cooling including welders, lasers, etc. A J-box version with a 5 amp relay is also available for direct control of higher electrical loads, such as chlorinator pumps. Applications:  Protect Bearings or Gears: oil separators, fuel systems, pumps, compressors, presses Electronics or Machinery: heat exchangers, semiconductor manufacturing equipment, induction furnaces, radio transmitters Process Systems: water filtration and reverse osmosis, chlorinators, de-icers, sterilizers, evaporators. Principle When the magnetic field of permanent magnet inside the shuttle or piston is moved into the proximity of the reed switch inside the stationary stem, the reed switch contacts “snap” together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch contacts move apart and the circuit is opened.
