Air Leak Testing Case of Electronic Scale

2018-12-12

Testing principle

Hairuisi sealing tester is a new ,high precision and non-destructive air leak tester .Our air leak tester adopts pressure principle and uses compressed air as the medium to detect leaks. It is a non-destructive testing instrument. The working principle is to apply a certain pressure to the inner cavity or outside of the product to be tested, then close the valve. After a period of stability, measure the change of the air pressure during the detection period and calculate the leakage amount by our precision sensor.This instrument is widely used in the sealing test of open products or sealed products with its high precision and full-featured features.


♦Product description 

With the development of electronic scale and the demand of special application occasions, the waterproofing of electronic scale has been paid more and more attention by consumers and manufacturers. and the waterproofing performance of electronic scale is also different due to the different waterproofing levels.In order to obtain the highest waterproof performance of the

electronic scale, the manufacturer will detect the tightness of the electronic scale.As a waterproof testing expert and developer of waterproof testing equipment, Hairuisi Technology also has

special research on waterproof testing of electronic scale. So, this time we will share a waterproof testing case of electronic scale for your reference.

The length and width of this electronic scale are 30 cm and 25 cm respectively. At the same time, the electronic scale has no air-filled hole, so it is necessary to make a suitable size mold for the electronic scale.

Corresponding to the characteristics of the electronic scale, Hairuisi Technology has customized a special mold for this electronic scale. The mold corresponds to the shape of the electronic scale. A groove is specially

placed on the weighing pan. 


 

♦Testing parameters

As customer's requirements ,The waterproof grade of electrical scale is IP67 .The testing pressure we set is 12KPA ,The mininum air intake we set is 10KPA .Since the testing product size is very big ,so the intake air time should be a little longer .Our intake air time is 5seconds and The time of air stability is 3seconds and the testing time is 5seconds .

 3.Put the testing product in the mold and press the start button .the fixture will seal the mold and Certain compressed air will be input from our instrument into the mold.

when input air time finished ,The valve will close and our instrument will measure the change of the air pressure during the detection period and calculate the leakage amount by our precision sensor.

when the testing time is finished ,The testing result (OK or NG )will be shown on our screen .
