He-490M: Mastery of the Mass Extraction Principle

He-490M Mass extraction

Industrial Context

The He-490M is a high-precision leak detection instrument based on Mass Extraction technology. Using advanced vacuum chambers and controlled extraction systems, it enables direct and highly sensitive measurement of leak rates in industrial applications requiring exceptional integrity control.

Operating Principle of the He-490M

The Mass Extraction principle consists of extracting and measuring the gas escaping from a test part placed in a vacuum chamber. Unlike conventional pressure decay methods, the He-490M directly measures the extracted gas quantity under stabilized vacuum conditions.

Test Cycle

The system performs a fully controlled sequence including chamber evacuation, stabilization, extraction measurement, and leak qualification.

Physical Foundations of Mass Extraction

Under vacuum conditions, gas naturally migrates from higher pressure regions toward lower pressure regions. The He-490M exploits this pressure differential to extract and quantify leaks with very high sensitivity.

Vacuum Chamber Technology

The He-490M uses high-performance vacuum chambers optimized to minimize background noise and thermal drift. This architecture significantly improves repeatability and detection capability for micro-leaks.

Key Advantages

Mass Extraction technology provides direct measurement, excellent repeatability, fast cycle times, and superior sensitivity for low leak-rate applications.

Comparison with Conventional Technologies

Compared with pressure decay or traditional mass flow systems, Mass Extraction enables improved sensitivity thanks to controlled vacuum environments and optimized extraction dynamics.

Typical Applications

Applications include battery housings, electronics, medical devices, aerospace components, and high-value assemblies requiring vacuum-compatible leak testing.

Key Technical Benefits

  • High-vacuum chamber architecture
  • Enhanced micro-leak sensitivity
  • Stable and repeatable measurements
  • Reduced thermal influence
  • Fast industrial cycle times
  • Direct extraction-based leak quantification

The He-490M positions Mass Extraction technology as an advanced solution for industrial leak testing. By combining controlled vacuum chambers with precision extraction measurement, it delivers superior performance for modern manufacturing environments.
