ATEX Level Switch – LS-52100(E) – Exi Intrinsically Safe
ATEX intrinsically safe level switch, also available in CSA explosion proof version.
These units solve the problem of point level sensing in tanks with inaccessible tops or bottoms, or at intermediate locations in larger tanks. Operation is positive and dependable. The float pivots with changing liquid level, displacing a shuttle which magnetically actuates a hermetically sealed switch within the unit. Installation is through the tank side at the detection point. Rugged, all-stainless steel unit offers broad chemical compatibility at temperatures to 300°F (149°C).
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.
