Helium Leak Testing Equipment For Battery Metal Shell With High Precision
Product information:
Our systems are based on a Mass Spectrometer Leak Detector that is connected to the vacuum line of a vacuum chamber. Helium is introduced inside the tested part. Any helium passing through a leak increases the helium partial pressure that is continuously monitored by the mass spectrometer.
The system consists at least of the following components:
A Mass spectrometer with its own vacuum system.
One chamber.
A vacuum group that evacuates the chamber thus reducing the helium partial pressure inside the chamber.
A valve manifold connected to the part that allows different steps of the detection routine (part evacuation, helium filling, helium exhaust, part venting…).
A power and control cabinet including touchscreen human operator interface.
Advantage:
Helium leak test equipment are the ideal solution for leak detection and leak-tightness testing under vacuum. The test gas Helium is safe and a small, light molecule which is suitable for detecting micro leaks. The detection range of Helium in vacuum tests lies between 10-2 and 10-13 Pa.m3/s. Helium leak detection is extremely accurate, quantitative and repeatable. Fast cycle times are a further advantage.Leak Testing Equipment
