New Energy Vehicle Sensor Airtightness Inspection Case

本次案例中我们对被测产品（新能源汽车传感器）进行了三次测试，按照客户产品的防护等级要求是 IP67，根据其产品的实际结构分析，我们使用的检测压力 15kPa，泄漏标准 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)

Summarize

Above is the airtightness testing demo case brought to you, welcome to pay attention to us, and subsequently share more test cases and industry solutions.
