Micro leakage sealing detector for electrical components

Testing principle:

电器元件微泄漏密封检测仪

Determine whether there is gas leakage in the test chamber by comparing the pressure between the standard chamber and the test chamber.

The reference container and the tested container are both sealed and leak free. After placing the sample into the tested container, the pressure change of the tested container is caused by gas leakage of the sample. The pressure change is detected by a differential pressure sensor, and the leakage hole diameter and leakage flow rate can be derived through formula calculation

test method	Method Explanation
Single sensor testing technology	A single sensor generally refers to the use of a pressure sensor, which is connected to the testing chamber and determines the test results based on the pressure changes of the sensor. This technology has low detection accuracy and can generally detect 5ccm (about 25 μ m leakage). The detection accuracy depends on the precision of the pressure sensor.
Dual sensor testing technology	Generally, it refers to the use of two types of sensors, pressure sensors and differential pressure sensors, in conjunction with a dual chamber comparative test. The test results are determined by monitoring the pressure changes of the differential pressure sensor. This technology has high detection accuracy and can distinguish leaks below 3 μ m.
Multi sensor testing technology	By adding force sensors or other types of sensors on the basis of dual sensor technology, and comparing multiple sensors, the testing accuracy and precision can be improved, and the leakage aperture can be calculated.

Technical advantages:

★ Optional built-in 10 inch touchscreen computer and external computer;

★ It can accurately display the leakage aperture (≥ 1 μ m) and leakage amount;

The test chamber and the host are arranged separately, and one set of test chambers is suitable for more than 5 specifications of samples;

★ The testing chamber is made of aluminum alloy or stainless steel, with pneumatic clamping;

★ Built in flow meter, one click completion of flow calibration;

★ Equipped with three calibration methods: zero point, leak hole, and flow rate;

The test results have three judgment modes: pressure attenuation, leakage aperture, and leakage flow rate

The test result shows that the flow error is less than or equal to 0.1 sccm

★ Vacuum resolution ≤ 1pa/0.01mbar/0.0001psi

★ Capable of converting testing units such as kpa/mbar/pa/psi
