Magnetic float level sensor consists of reed, precise resistance, and amplification transformation circuit and adopts imported advanced sensor components and signal transmitters. When the magnetic line of the magnetic float ball reaches a certain place of the level sensor, the reed closes, and the float ball changes with the height of the level interface. The amplification transformation circuit converts the change of the interface height into a linear 4~20mADC signal to realize the measurement and transmission of the level location signal.
