Helium Leak Detector - Global Industry Market Analysis Report 2020-2031

A helium leak detector is a professional instrument designed to detect and measure helium escaping from a test object. In many industries that have extremely high requirements for system sealing, helium leak detectors play a key role, accurately finding tiny leaks and ensuring the safety and integrity of various systems and products.

From the working principle, helium leak detectors mainly work based on the unique properties of helium and related physical principles. As an inert gas, helium has the characteristics of small molecular size, stable chemical properties, non-toxicity, and non-flammable and non-explosive, which makes it an ideal tracer gas. When there is a leak in the system, helium can easily pass through tiny pores. During the detection process, helium is usually introduced into the system being tested or sprayed outside the system. If there is a leak in the system, helium will escape, and the helium leak detector can capture the leaked helium and detect it. For example, the core component of the common mass spectrometer helium leak detector is a mass spectrometer, which ionizes helium through an electron beam, and then separates and detects it according to the different mass-to-charge ratios of the ions under the action of electric and magnetic fields, so as to determine whether there is a leak and the location and extent of the leak.

Helium leak detectors are mainly divided into the following types. The first is a mass spectrometer leak detector, which is the most common and highly sensitive one. It uses a mass spectrometer to specifically identify helium molecules, and can provide extremely accurate and sensitive leak detection capabilities. It can detect extremely small leaks, such as leaks as low as 1×10⁻¹² mbar・l/s. The second is a helium sniffer, which is a portable device mainly used to locate leaks in pressurized systems. It helps technicians quickly determine the location of leaks by inhaling air samples and analyzing whether there is helium in them. It is widely used in on-site inspections of some large equipment or complex systems.

In terms of application areas, helium leak detectors are present in many industries. In the aerospace field, it is used to detect fuel systems, oxygen systems, and spacecraft components to ensure flight safety, because any small leak may cause serious accidents. In the automotive industry, it can be used to check air conditioning systems, fuel lines, and engine components to ensure the normal operation and stable performance of the vehicle. In the electronics field, it can ensure the airtightness of semiconductor packaging and prevent external impurities from entering and affecting chip performance. In the medical industry, it is used to verify the integrity of implantable devices and drug packaging to ensure the health and safety of patients. In the refrigeration industry, it detects leaks in the cooling system to improve refrigeration efficiency and equipment life. In the field of scientific research, it maintains the vacuum integrity of scientific instruments to ensure the accuracy of experimental data.

There are many different detection methods for helium leak detectors. In the vacuum test method, the system is first evacuated by an external vacuum pump or the system's own vacuum pump, and then helium is sprayed at the suspected leak. If there is a leak, the helium molecules will penetrate into the chamber, and the helium leak detector sensor inserted into the vacuum chamber can detect it, thereby determining the leak location. In the pressure test method, the object to be tested is first filled with helium or a mixture of helium and air, and then the suspected leak point is scanned with a helium leak detector. If helium is detected, the leak detector will sound an alarm to determine the leak location. In the accumulation method, the object to be tested is placed in a sealed chamber and filled with helium. After a period of time, the presence of helium in the atmosphere in the chamber is analyzed to determine the overall leakage rate of the object.

With the continuous advancement of science and technology, helium leak detectors are also developing continuously. In the future, it will develop in the direction of intelligence, high sensitivity, miniaturization and multifunctionality. In terms of intelligence, by introducing artificial intelligence technology, automatic analysis and processing of leakage data can be achieved to improve detection efficiency and accuracy. In terms of high sensitivity, new detection technologies and materials are continuously developed to further enhance the detection ability of tiny leaks. In terms of miniaturization, more portable equipment is developed to facilitate detection in different scenarios. In terms of multifunctionality, it can detect multiple gases at the same time to meet the diverse needs of different industries.
