NYFQ Float Level Switch Liquid Level Alarm
NYFQ series float level switch is based on buoyancy and magnetic principle. Technical advantages of floating ball level switch: floating ball switch does not contain bellows, springs, seals and other components that lead to failure. Instead, a straight float is used to drive the internal magnet of the switch, and the simple lever of the float switch makes the switch move instantaneously. Float cantilever Angle limit design, prevent float vertical. Float level switch is a kind of simple structure, easy to use, safe and reliable level controller. It is faster than the general mechanical switch, long working life; Compared with the electronic switch, it has the characteristics of strong resistance to load impact, a product can achieve multi-point control. It has been widely used in shipbuilding, paper making, printing, generator equipment, petrochemical industry, food industry, water treatment, electrician, dye industry, hydraulic machinery and other aspects. Float switch is a kind of simple structure, easy to use, safe and reliable liquid level control device, it has a small volume than the general mechanical switch, fast speed, long service life, compared with the electronic switch, it has the characteristics of strong resistance to load impact.

The magnetic float of the float level switch is used to rise or fall with the liquid level, so that the dry reed tube chip at the set position in the sensor detection tube moves, and the contact on (off) conversion signal is sent.
In airtight non magnetic conductivity tube fitted with one or more of the dry reed pipe, then the tube through one or more hollow and internal ring magnets floating ball, rise or fall of liquids will drive the floating ball move up and down together, so that the non magnetic conductivity tube suction reed tube or disconnect, so as to output a signal switch
