FS-200E-A – Adjustable Type Flow Switch

The FS-200E  flow switch offers accurate flow detection with 1% repeatability and European G1″ port size. The durable construction delivers long life repeatability in either water or oil. The design of large flow paths keep pressure drop low, thus are ideal for detection of flow in high volume lubrication, cooling or process applications. The FS-200E Adjustable versions offer the same accuracy with the additional feature of external adjustment.


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.
