Dear Friends For those who are intersted I tell my experiment with crane remote control beside an induction furnace.
Induction furnace which we tested with, has 3MW input energy and about 400Hz frequency (from BBC). Power circuits are placed below the surface inside an armed concrete room. Our system working in 433MHZ did not have any problem with electromagnetic inteference with the receiver located about 2 meters from furnace. Actually there was no harmonics in FM and SW band at all using a radio reciever. But I could hear very strong noise in all LW and MW band even in very far distances from the furnace.(uo to 1600KHZ could be monitored) Actually our main problem there will be very high temperature and harsh environment conditions.
