In daily work and life, we often need to use positive pressure sealing tester. So what is the principle of positive pressure sealing tester?
What is the principle of positive pressure seal tester
Positive pressure sealing tester is an instrument used to test the sealing performance of product packaging. Its working principle is based on the following two aspects:
- The positive pressure sealingtester is a positive pressure source (such as gas) that provides stable pressure. After filling a certain pressure of gas into the sample by setting parameters, the pressure sensor is used to detect the pressure change inside the sample to judge the overall sealing performance of the sample, and the pressure resistance and burst performance of the sample are tested with the specified air pressure. .
- The positive pressure sealingtester is equipped with a pressure sensor to measure the pressure in the system. The sensor can detect small pressure changes in the system. The positive pressure seal tester compares the pressure data measured by the sensor with the preset standard. If the test system leaks, the pressure will drop, and the tester can determine the degree of leakage and the location of the leakage through data analysis.
By continuously increasing the pressure of the positive pressure source, the tester can also evaluate the pressure resistance of the product packaging. During the test, the relationship between pressure and time can be recorded to obtain information about the reliability and durability of the product.
In general, the positive pressure sealing tester tests the sealing performance of the product packaging by applying a certain pressure to the product packaging, thereby evaluating and verifying it. This is a commonly used testing method, widely used in many industries such as food, medicine, medical treatment, and daily chemicals.
