Rod type float level switch

PrincipleA sealed stainless steel tube (non magnetic conductivity) pass through one or more of the ring magnet floating ball, there are some single contact dry reed switches in the stainless steel tube, and reed switches are distributed on the position of alarm point, the liquid level rising or dropping will drive floating ball move at the same time, when the float magnet reaches to the location of alarm point, reed switch will act and output switch signal.
