The float level IEXD are built in accordance with the ATEX Directive (94/9/ EC) for use in the control of different levels of a liquid in a tank located in a generic environment where there is an explosive atmosphere for a long period, consisting of a mixture with air or flammable substances in the form of gas, vapor or mist (zone 0 - ref. EN 60079-10). The level switches IEXD are marked
The level switches are based on the interaction between magnetic field and a reed switch, with a single contact for each level of the liquid to be monitored: when the float of the indicator meet the Reed switch incorporated in the tube at the pre-established distances, the contact activated by the magnet housed in the float opens or closes, thus obtaining the possibility of sending a luminous or acoustic signal or disconnecting any electronic device connected to it.
The changeover takes place without direct contact between the reed and the liquid.
The indicator must be fitted in the vertical position, and the float must be at least 35mm from ferrous surfaces (walls, tanks, etc.). A gasket (flat or toroidal) guarantees from leakage through the hole of the level indicator
These level switches allow you to stay bimentallic thermostat or an PT100 in order to monitor, discretely and continuously, the temperature reached by the liquid inside the tank.
