Heliumlekkasjesøk

Heliumlekkasjesøk, also known as helium leak detection, is a highly sensitive method used to identify and locate leaks in various systems. This technique utilizes helium, an inert and easily detectable gas, as a tracer. Helium is chosen because of its small atomic size, low viscosity, and the fact that it is non-flammable and non-toxic, making it safe to use in many applications.

The process typically involves introducing helium into the system that needs to be tested. Then, a helium mass spectrometer leak detector is used to scan the exterior of the system. This detector is designed to specifically identify the presence of helium atoms. When helium escapes through a leak, it is drawn towards the detector's intake. The mass spectrometer then analyzes the gas and registers a signal if helium is present, indicating a leak.

Helium leak detection is widely employed in industries where maintaining vacuum or pressure integrity is critical. This includes the manufacturing of semiconductors, automotive components, refrigeration systems, and medical devices. It is also used in nuclear power plants, aerospace, and research laboratories. The sensitivity of helium leak detection allows for the identification of very small leaks that might be missed by other methods. The precise location of the leak can be pinpointed by moving the detector probe along the suspected areas until the helium signal is strongest. This accuracy is crucial for effective repair and to prevent system failures.
