NYFQ series float level switch is designed based on the principle of buoyancy and magnetism. The magnetic float of the float level switch moves with the liquid level, causing the reed switch chip at the set position in the sensor detection tube to operate and send out a contact opening (closing) conversion signal. One or more reed switches are installed in a closed non-magnetic tube, and then the tube is passed through one or more hollow floats with annular magnets inside. The rise or fall of the liquid will drive the float to move up and down, so that the reed switch in the non-magnetic tube will produce an action of attraction or disconnection, and output a resistance signal or switch signal corresponding to the liquid level.
