Working principle:


     The small float switch, small liquid level controller and liquid level sensor are mainly composed of a reed

switch and a float. The float has magnetic material. When the float moves up and down with the measured liquid level, the reed switch is touched to detect the liquid level position.

The type of our magnet material:


Ferrite permanent magnet material (Ferrite)
1. NdFeB magnet It is the magnet with the highest commercial performance. It is known as the magnetic king. It has extremely high magnetic properties and its maximum magnetic energy product (BHmax) is more than 10 times higher than that of ferrite. Its mechanical processing performance is also quite good. Operating temperatures up to 200 degrees Celsius. Moreover, its texture is hard, its performance is stable, and it has a good cost performance, so its application is extremely extensive. However, because of its strong chemical activity, it must be treated with a surface coating. (such as Zn, Ni, electrophoresis, passivation, etc.).


2. Ferrite magnets Its main raw materials include BaFe12O19 and SrFe12O19. It is made of ceramic technology and has a relatively hard texture. It is a brittle material. Because ferrite magnets have good temperature resistance, low price and moderate performance, they have become the most widely used permanent magnets.


3. Alnico magnets are alloys of aluminum, nickel, cobalt, iron and other trace metals. The casting process can be processed into different sizes and shapes, and the processability is very good. Cast AlNiCo permanent magnets have the lowest reversible temperature coefficient and can operate at temperatures above 600 degrees Celsius. AlNiCo permanent magnet products are widely used in various instrumentation and other applications.


4. Samarium Cobalt (SmCo) is classified into SmCo5 and Sm2Co17 depending on the composition. Its development is limited due to the high price of its materials. Samarium Cobalt (SmCo), as a rare earth permanent magnet, has a high magnetic energy product (14-28 MGOe), reliable coercivity and good temperature characteristics. Compared with neodymium iron boron magnets, samarium cobalt magnets are more suitable for working in high temperature environments.





     Our testing equipment is a helium mass spectrometer. It is the first in China to use this equipment to detect floats, so that the floats that our factory goes out are 100% leak-free. In addition, after the factory quality inspection, we will also carry out The second test, mainly to check whether the appearance of the product is uneven, to ensure that our products go out are all fine, we can say that our quality testing is the  No.1 or No.2 in China.After 2 tests, we will send a test report to the customer, which is listed below.:
