Test schematic
Open Y1 and Y2, and simultaneously charge a certain pressure of gas into the standard workpiece and the tested workpiece with equal volumes. Then close Y2. After the pressure is balanced and stabilized, measure the pressure difference between the standard workpiece and the tested workpiece. This difference is the actual leakage value. Since the sensor for obtaining the pressure difference is independent, this test method is not affected or limited by the inflation pressure and has a very high accuracy.
1、Delay Time: The time to wait for the fixture to clamp the product, with a setting range of 0.1 - 999.9 seconds.
2、Inflation Time: Pressurize the product according to the preset pressure, with a setting range of 0.1 - 999.9 seconds.
3、Equilibration Time: The time to wait for the airflow and air pressure to stabilize, with a setting range of 0.1 - 999.9 seconds.
4、Measurement Time: Detect the leakage amount △P or leakage rate sccm within a certain period, with a setting range of 0.1 - 999.9 seconds.
5、Exhaust Time: The time for exhausting gas after the test, with a setting range of 0.1 - 999.9 seconds.
ATC800 series air leak tester is widely used in parts leak detection of auto parts, mobile phones, smart wearables, smart watch, earphones/headphones, medical equipment, electronic appliances, household appliances, automotive three-electric system,gas appliances and other industries.
