In the manufacturing industry, the airtightness of a product is a crucial quality indicator. In order to ensure that the product meets the quality standards and meets the customer's requirements, a variety of air tightness testing equipment is required. Among them, the differential pressure air tightness tester is a commonly used tool, which can accurately detect whether the product has air tightness problems. This article will introduce the working principle of differential pressure air tightness tester and its application.

Differential pressure air tightness tester is a kind of testing equipment based on the principle of differential pressure sensor. Its working principle is based on the relationship between the amount of leakage and the differential pressure, and the difference in air pressure around the product is measured to determine if the product has an air tightness problem. The following is a detailed explanation of the working principle of the differential pressure air tightness tester:

Establish a pressure differential: The differential pressure air tightness tester first establishes a pressure difference around the product. Typically, the product is filled with compressed air or helium, resulting in a difference in pressure between the inside and outside of the product.

Differential pressure is measured: The test instrument is equipped with a high-precision differential pressure sensor to measure the differential pressure around the product. Differential pressure sensors accurately detect small pressure changes and transmit this data to the control system of the testing instrument.

Compare and analyze: The control system compares and analyzes the measured differential pressure data with a preset standard value. If the measured differential pressure value exceeds the set threshold range, the system will issue an alarm and indicate to the operator that there is a leak problem with the product.

The results are displayed: Differential pressure air tightness testers are usually equipped with a display or interface connected to a computer to display test results and data. Through these interfaces, operators can intuitively understand the airtightness status of the product and deal with it in a timely manner.

Differential pressure air tightness tester has a wide range of applications in the manufacturing industry, especially in the fields of automobiles, electronic products, medical devices and other fields. It can quickly and accurately detect the air tightness of products, helping enterprises improve product quality and production efficiency. At the same time, by timely discovery and repair of air tightness problems, it can also avoid potential safety hazards such as air leakage and leakage during the use of the product, and protect the interests of users and brand reputation.

Overall, differential pressure air tightness testers are a reliable and efficient testing device in the manufacturing industry by measuring the pressure difference around the product to determine whether the product has air tightness problems. With the continuous progress of technology and the continuous expansion of applications, it is believed that the differential pressure air tightness detector will play a more important role in the future to help enterprises achieve quality control and continuous improvement.
