Abstract (en)
Industrial vacuum cleaner (1) for liquid substances with detection device (2) of the level of filling of its collection tank. Said vacuum cleaner provided with a vacuum turbine (3) comprises: - a collection tank (4) of the vacuumed liquid products (L); - an electrical control unit (5) for controlling the various functions; - a detection device (2) of the level of liquid reached in said tank (4), comprising a housing (6) obtained in said tank (4), a float (7) and a micro switch (8), wherein said float (7), rising as a result of the increase in the level of liquid (L), cooperates with said micro switch (8) to change its status and generate a control signal, manageable by said electrical control unit (5), to stop said vacuum turbine (3) upon reaching a predefined maximum level of filling; - transmission means of said control signal from said detection device (2) to said electrical control unit (5). Said detection device (2) comprises a circuit board comprising an emitter (9) of an electromagnetic wave control signal, said control signal being generated as a result of the change in status of said micro switch (8). Said electrical control unit (5) comprises a receiver (10) adapted to receive said electromagnetic wave control signal, and said transmission means of said control signal are of wireless type.
