FS-400(E)-(A) – Exi Intrinsically Safe ATEX Flow Switch

FS-400(E)-(A) – Exi Intrinsically Safe ATEX Flow Switch ATEX intrinsically safe version of the standard FS-400(E) series flow switch. The FS-400 and FS-400-Adjustable ATEX flow switch provides 1% repeatability. The unit may be fitted instead of a pipe elbow where space is at a premium. 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.
