Industrial Leak Detection at Bellows and Compensators

 

Bellows and compensators are vital for many industrial applications. They are present in exhaust lines of vehicles, for example, as well as in the pressure switches of cooling technology. For their correct function, tightness is crucially important. Industrial leak detection of these parts must be adjusted to the specific field of their application. Therewith, some boundary conditions for leak detection are already set:

1. The test procedure has to be non-destructive. The maximum test pressure is thus given by the elastic limit of the material that is tested.
2. The test procedure must at least simulate the real use of the part but better contain a security limit. This requirement determines the pressure direction as well as the pressure in a burst pressure test, which is carried out upstream the actual leak test.
3. The production processes must be controllable at least qualitatively, but better quantitatively. Changes in the material that are caused by the production process have to be measurable.
