Rod type Multi-point float level switch

Rod type float level switch is widely used to control the level of liquids such as water, waste water, acid solution, alkaline solution and diesel.

Product Description


A sealed stainless steel tube (non magnetic conductivity) passes 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 to move at the same time. When the float magnet reaches the location of alarm point, reed switch will act and output switch signal.预览更改 (在新窗口中打开)
