Abstract
The invention relates to a test gas leakage detection apparatus (1) comprising a test chamber (2) and supply and measuring devices such as fore-pumps and high-vacuum pumps, test gas detectors, electronic components, etc. In order to construct an apparatus of this type in a manner which is simple and which does not restrict mobility, the invention provides that the test chamber (2) and the supply and measuring devices are combined to form a modular unit, and that the test chamber (2) is supported on a housing (3) in which the supply and measuring devices are accommodated. In addition, air cooling devices are assigned to thermally critical components of the supply and measuring devices.
Claims7
Apparatus for testing sealed packages containing a test gas for leaks that includes:
- a mobile housing that is fully contained and capable of testing said sealed packages at various locations thru a manufacturing or distribution facility;
- a test chamber for enclosing a package containing a test gas supported upon said housing,
- vacuum means for evacuating the test chamber, where said vacuum means is also mounted within said housing,
- gas detecting means mounted within housing for analyzing the gas within the evacuated test chamber to determine the presence of a test gas;
- and
- air cooling means mounted within said housing for passing cooling air over thermally critical components associated with said vacuum means and said gas detecting means.
