The operating principle of the magnetic level switches is based on the action of a magnet housed in a float on some contacts housed inside a hermetic tube. When the float reaches the point where the contact is, it switches by providing a signal that will be used to start an alarm, act on an automaton, stop a pump or activate a solenoid valve.
The versatility of these teams is demonstrated by the ability to generate a multitude of variants combining materials, process connections, electrical connections, quantity, type of contact, etc. Except for the miniature models, the rest of the models are made to measure adjusting to the characteristics of the tank, the working conditions and the requirements of electrical control.
Proper protection and maintenance measures will provide a long life for these equipments.
