Helium Leak Detection Systems
Many industrial products are required to guarantee a high degree of tightness, either to ensure correct functioning during their whole life cycle, or to avoid emissions of high global warming potential gases such as refrigerants and SF6.
Helium leak detection inside a vacuum chamber is the preferred method when you rapidly need to ensure high sensitivity and total reliability, as well as independent operator tests on your product.
We provide customized solutions ranging from manual systems to automated machines that are fully integrated in a production line.
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.
