Introduction of Helium Leak Detector:
Helium leak detectors are used to detect and locate leaks in various systems, including vacuum systems, refrigeration systems, and pipelines. They work on the principle of mass spectrometry, which involves ionizing helium atoms and measuring their mass-to-charge ratio to detect the presence of leaks.
The basic working principle of a helium leak detector involves introducing helium gas into the system being tested and then using a mass spectrometer to measure the concentration of helium outside the system. If there is a leak in the system, helium will escape through the leak and be detected by the mass spectrometer.
