Industrial Leak Detectors

Industrial leak testing using HELIUM as the test gas is characterized above all by the fact that the leak detection equipment is fully integrated into the manufacturing line. The design and construction of such test units will naturally take into account the task to be carried out in each case (e.g. leak testing vehicle rims made of aluminum or leak testing for metal drums). Mass-produced, standardized component modules will be used wherever possible.

The parts to be examined are fed to the leak testing system (envelope test with rigid envelope and positive pressure or vacuum inside the specimen; see respective sections above) by way of a conveyor system. There they will be examined individually using the integral methods and automatically moved on. Specimens found to be leaking will be shunted to the side.

What are the advantages of the helium test method?

The advantages of the helium test method, seen from the industrial point of view, may be summarized as follows: 

• The leak rates which can be detected with this process go far beyond all practical requirements. 
  
• The integral leak test, i.e. the total leak rate for all individual leaks, facilitates the detection of microscopic and sponge-like distributed leaks which altogether result in leakage losses similar to those for a larger individual leak. 
• The testing procedure and sequence can be fully automated. 
• The cyclical, automatic test system check (self-monitoring) of the device ensures great testing reliability. 
• Helium is non-toxic and non-hazardous (no maximum allowable concentrations need be observed).
• Testing can be easily documented, indicating the parameters and results, on a printer. 

Use of the helium test method will result in considerable increases in efficiency (cycling times being only a matter of seconds in length) and lead to a considerable increase in testing reliability. As a result of this and due to the EN/ISO 9000 requirements, traditional industrial test methods Industrial leak testing
