Helium Leak Detection | BBS Automation

The Most Sensitive Way to Detect Leaks

Helium leak detection systems (HLDS) are most sensitive. Our helium leak detection systems check parts and devices for the smallest flaw. They offer the perfect combination of highly advanced leak detection features plus uncompromised industrial ﬂexibility and durability for high-vacuum applications.

The advantages of the BBS-HLDS, whether integrated into an assembly line or as a stand-alone unit, lead to faster test and assembly cycles, higher quality levels, and better process reliability — improving product quality.

Why do we use helium to locate leaks? Helium has many advantages. It occurs only in low concentrations in the ambient air and can easily be detected. Helium is non-toxic and does not react with other materials. The small atomic radius enables quick tests and the detection of even the smallest leaks. Additionally, our special helium recovery systems help to reduce emissions and costs during production.

**Sniffing Test**
The product is filled with helium. In case of leaks the gas escapes through the leakage channel and is detected by a sniffer probe. The probe can be moved manually or automatically via a robot.

**Spraying Test**
First a vacuum is created in the product. The tracer gas is distributed over the product with a spray probe and can penetrate the leak.

**Bombing Test**
The method is used for products that cannot be connected directly to a leak detector. The product is placed in a chamber containing pressurized helium. The helium penetrates into the product. The actual test then takes place in the vacuum chamber, to which a helium detector is connected.

**Accumulation Test**
The product is placed in an accumulation chamber and filled with tracer gas. Gas which escapes through leaks is equally distributed throughout the chamber via fans. The leak detector measures the total leakage rate of the test item.

**Hard Vacuum Leak Test**
The product is filled with helium in an evacuated vacuum chamber. In case of a leak, the gas escapes through the leak and is measured by a helium leak detector which is connected to the vacuum chamber.
