Introduction of Helium Leak Detector
Helium Leak Detector - High Sensitivity Leak Detection Technology
A helium leak detector is a mass spectrometer designed to detect helium gas with a high vacuum system and a mass spectrometer chamber connected to it. When an external gas enters the mass spectrometry chamber, it is ionized at the ion source and produce ions. The gas ions are accelerated into the magnetic field and their paths are deflected, with different radii due to the different charge-to-mass ratios of different ions. By placing a slit at a suitable place, only the ions of the tracer gas, helium, can pass through and reach the collecting pole. The ion flow signal obtained at the collection pole is proportional to the amount of helium entering the leak detector, i.e. the magnitude of the leak rate. By measuring this signal, the leak rate can be measured.

Applications of Helium Leak Detector:
Helium mass spectrometry has been widely used in the field of vacuum leak detection technology, the advantages of this method are: high sensitivity of leak detection, fast response time of the instrument, high diffusion speed of helium molecules in the high vacuum environment of the instrument; so helium leak detector has been widely used in many fields.
Aerospace field: spaceships, space shuttles, rockets, satellites, airplanes, etc. These all use vacuum leakage detection technology.
General industrial fields: atomic energy, power plants, power distribution stations, automobile manufacturing, shipbuilding industry, refrigeration industry, metallurgical industry, gas pipelines, gas tanks, oil tanks, boilers fast food packaging and so on can not be separated from the problem of leakage detection.
Helium leak detector is used for leak testing of special components such as fuel storage tanks and fuel transportation pipelines.
