LS-1700(E) – EXi Intrinsically Safe ATEX Level Switch

ATEX intrinsically safe version of the standard LS-1700 level switch.

Ideal for shallow tanks or restricted spaces, or for low-cost, high volume use the LS-1700(E) ATEX level switch offers broad chemical compatibility for general purpose use. Also ideal for oils and water.


When the magnetic field of permanent magnet inside the float is moved into to 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.
