New Energy Vehicle Sensor Airtightness Inspection Case
In this case, we conducted three tests on the product under test (new energy vehicle sensor), according to the customer's product protection level requirements is IP67, according to the actual structure of the product analysis, we use the detection pressure 15Kpa, leakage standard 65Pa.
Ⅰ.First test
leakage pressure44Pa(< 65 Pa leakage standard).Passed test results
Ⅱ.Second test
In order to facilitate the comparison effect, the second time we put a piece of hair in the middle of the sealing ring and fixture of the product under test, the leakage value of the instrument is visible to the naked eye to expand to94 Pa(> 65 Pa leakage standard), instrument alarm.Failed test results
III.Third test
In order to verify the repeatability of the leakage detection, we removed the hair strands and tested them again, and the results of the third test showed that45Pa(< 65 Pa leakage standard).Passed test resultsThe results are basically the same as those of the first test, which also proves the high precision of our testing instruments.Tolerance within 1Pa(Accuracy can be 0.1Pa according to test requirements)
