The floats are to be used to control the level in the filling and emptying processes of tanks, wells and containers in which aggressive liquids, like acids, alkaloids and a wide range of chemical products or hydrocarbons are used.

The models are certificated for use in potentially explosive Dust or Gas atmospheres hazardous areas.

When the level of the liquid reaches the level of the float switch, the float changes its position an angle, the ball inside its deviated and activates a micro switch due to this deviation.

It is necessary to install 2 devices to control of the maximum and the minimum levels automatically.

It is simple: the switch literally hangs on its own cable at the desired height and is fixed to the ceiling or to one side of the tank.

For use in potentially explosive Dust atmospheres hazardous areas the installation must be done according to the Standard and Normative documents. For use in potentially explosive Gas atmospheres hazardous areas the installation must be done according to the Standard and Normative documents and comply with EN 50014, clause 6.1.
