In modern manufacturing, product quality control is critical. Among them, airtightness and watertightness testing is an indispensable part of many industries.
Today, let's take a look at this 'Leak Detector' in the QC world -Differential Pressure Airtightness Tester. This paper will explore itsWorking principle, advantages and disadvantages, application prospects, and precautions for use.
First, what is the differential pressure air tightness tester
Simply put, it's aHigh-precision testing equipment that determines whether a product has a seal leak by comparing the pressure difference between a standard product and a test product.. It's like an attentive detective, able to accurately capture minute changes in pressure, theFinding the tiny "loopholes" that are hard to detect with the naked eye, and avoiding the flow of defective products into the market.

1. High precision:
JCGK's Differential Pressure Airtightness Tester uses dual sensors to detect very small pressure changes, allowing for highly accurate 0.1Pa resolution leak detection.
2. Low environmental disturbance:
Due to its unique working principle, the differential pressure detector is able to effectively reduce the influence of environmental factors such as temperature and humidity on the detection process.
3. High repeatability:
This tester is particularly suitable for products that require batch testing or long-term monitoring of airtightness, with a high degree of consistency in the results of multiple measurements.
Precision casting differential pressure leak testing cases, test results can be selected from two modes of pressure drop and leakage rate
inferior
1. Higher costs:
Compared to direct pressure airtightness testers (accuracy resolution 1 Pa), differential pressure testers (accuracy resolution 0.11 Pa) have higher technical requirements, resulting in higher costs and selling prices.
2. Operational complexity:
Specialized training of operators is required to ensure proper use and interpretation of test results.
II. Prospects for applications
With the continuous improvement of product quality requirements in various industries, the market demand for differential pressure airtightness tester is growing continuously. Especially in automotive manufacturing, aerospace, medical devices and other fields, the demand for high-precision airtightness testing is particularly urgent. With the progress of sensor technology, big data analysis and the application of AI algorithms, this "quality inspection tool" will become more intelligent and efficient.
Sure.The airtightness testing industry is also facing fierce competition and rapid technological updates. For example, the market is now seeing the emergence of integrated multifunctionalPositive and negative pressure quantitative airtightness tester, positive and negative mixed differential pressure airtightness testerand other equipment, all customized to meet the growing needs of the market.These devices can be customized by looking for professional airtightness testing manufacturers, such as Jingcheng Gongke Airtightness.But it is this competition and innovation that drives the continuous progress of testing technology and brings us better and safer airtightness testing equipment.
III. Precautions for use
To ensure the accuracy and reliability of the Differential Pressure Airtightness Tester, the following points should be noted when using it:
1. Integrity of Reference Standards:
It must be ensured that the standard to which the standard interface is mated is leak-free.
2. Consistent testing environment:
The test environments of the standard and the product under test must be identical, including whether or not they are immersed in water, the area of the package, and the material of the underpad. It must be ensured that the Reference Standard to which the standard interface is mated is leak-free.
3. Interpretation of data:
Small negative values (e.g. -3Pa, -8Pa) in the test data may be caused by dimensional tolerances of the test article and the standard or by environmental factors, and can be regarded as no leakage. However, if large negative values occur frequently, it is necessary to check whether there is leakage in the standard.
Summarize
