Vacuum Leak Detectors and Helium Leak Detectors

Helium leak detectors 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 · m 3 /s.

Helium mass spectrometer - Wikipedia

A helium mass spectrometer is an instrument commonly used to detect and locate small leaks. It was initially developed in the Manhattan Project during World War II to find extremely small leaks in the gas diffusion process of uranium enrichment plants. It typically uses a vacuum chamber in which a sealed container filled with helium is placed. Helium leaks out of the container, and the rate of the leak is detected by a mass spectrometer.

Ultimate Guide to Vacuum Leak Detection

In the “local” testing method the chamber is either internally pressurised with helium, or internally evacuated with helium then sparingly sprayed onto the surface of the chamber at likely leak-prone points. In both tests, helium enters the leak detector via possible leaks, and passes to the mass spectrometer for analysing.

Vacuum Chamber – Helium – Vacuum Technology …

The unit is then leak tested by evacuating the chamber and condensing unit, charging the unit with helium, and detecting any helium leaking from the unit into the chamber using a mass spectrometer. After a quickcheck at low pressure to detect and reject any part with a large leak that could otherwise slow production, the unit is pressurized with helium, typically to 150 psig, for the sensitive ...

Leak Testing & Pressure Testing: Guide to Helium Leak ...

Helium bombing is achieved through forcing a leak by pressurising the device within a helium gas chamber. Typically, the chamber is first evacuated to remove barometric pressure air from round the parts and then pressurising with bottled balloon gas.

Helium Leak Detection is very niche; if you’ve never been involved with it, you’ve probably never heard of it. Luckily, there are companies out there, although very few of them, that have very good helium knowledge and can provide you with a plethora of solutions to find your tiny leaks.

Leak detection - CERN

Helium is most commonly used since it fulfils all conditions mentioned above. Therefore the leak rate is usually given as helium standard leak rate (He Std) assuming a pressure difference of 1 bar from air to vacuum. The small diameter of the helium atoms allows the detection of very small leaks.

In the pressure test method, the test chamber is first filled with helium gas or a mixture of helium gas and air. Leak suspected sites are then scanned by the leak detector. If there is a helium gas, the leak detector starts to sound the alarms, and so the location of the leak is determined (Figure 3).

Helium Testing Systems | VES - Vacuum Engineering Services

Your leak path will always follow the very basic physics principles and higher pressure will try to equalise with lower pressure around it, thus you must drive your leak path in the correct direction by pressurising the outside or the inside with helium (P1V1=P2V2). In a hard vacuum chamber machine this is done by following step 1 with a helium ...
