Description  of  water level float switch :

PP plastic foam ball float liquid level switch is fixed size through the plastic mold injection 

molded parts, is a simple, easy to use liquid level control devices, it has no complex circuit,

 would not be disturbed, as long as the material selection is correct, any nature of the liquid, 

pressure and temperature can be used.   

Liquid dielectric properties and float: b. liquid specific gravity 

is not the same as float action will vary, SG hours than water, 

will float is immersed in a liquid increases. Float switch products refer to 

the proportion of water (SG=1) used to be considered when choosing float liquid level

 the proportion of SG, denoted by the floating ball specifications must be over, otherwise, 

the float switch unable to float high viscosity empty liquid stainless steel ball float.

PP float switch is sensing Reed switches using a magnet, so the fluid to be measured 

should not be iron, or iron filings stuck float float floating above would affect the float side 

of switch operation. 

  Use: PP float switch designed for a variety of home appliances, humidifier, water cooler, 

constant temperature and humidity, salt fog machines, printing machines, medical equipment,

 beverage machines, and compression tank liquid level detection, signal transfer, switch alarm, 

can be applied to a variety of health, environmental protection, toxic, with strong acid and alkali 

corrosive liquid used. Float selection Description: follow the measured temperature, pressure, 

specific gravity, acid properties, choose one of the following variety of float.

Liquid dielectric properties and float: 

B. liquid specific gravity is not the same as float action will vary, SG hours than water, 

will float is immersed in a liquid increases.   

C. the float switch products refer to the proportion of water (SG=1) used to be considered 

when choosing float liquid level the proportion of SG, denoted by the floating ball specifications

 must be over, otherwise, the float switch unable to float.    

D. viscosity liquids of high dries, should generally use large outer diameter stainless steel ball float. 

E. float switch is sensing Reed switches using a magnet, so the fluid to be measured 

should not be iron, or iron filings stuck float float floating above would affect 

the float side of switch operation.

Temperature: PVDF ball maximum temperature 120 ℃, 

PP float up to 80 ℃, 

stainless steel 304/316 of up to 200 degrees centigrade. 

Ball size: φ 26*17 ,φ 26*10,φ 26*26, φ19*16.5, φ18*8,φ 24*16.5,φ 29*12.5,   

 plastic floating ball molds of various sizes. 

Sticky: ball diameter should be chosen a larger proportion of small float to 

overcome the surface tension of liquids.

 Where these Magnetic float water level sensor switch  use for ??

For example :

Specifications:

Nice design,.

light weight ,

easy installation,

Low cost:

wide using application,

hermetically sealed,

suit for tough environment and long life,

Quality control takes on high priority.

Development team support.

After sale services.

Working theory:

The float switch is a device used to sense the level of liquid in a tank.

When the float ball of the level switch rises or falls with the liquid. The magenetic force of magnet.

which inside of the float ball will cause the reed switch to turn on( which tell the signal out) , change to Normally Closed. When the float ball move away

from the reed switch, the reed switch will turn off, change back to Normally Open.

Where to use ?  

This product can be used in liquid level control for watering machine , 

water heater , solar energy ,air conditioning , vending machine,

BSD-P,water dispenser, Humidifier, dehumidifier, fluid control ,

a pump, alarm device, moisturizing machine , bathroom utensil ,  oil tank , water tower and chemical industrial ,etc. 

And widely applied in motor vehices ,industrial equipment , 

agricultural equipment and household electrical appliances in future.
