Abstract: The present invention relates to a leak detection system for checking the leak-tightness of an object, the system including: a device for pressurising a space; a first pressure sensor configured to measure the variations in pressure of the pressurised space; a second pressure sensor configured to measure the variations in ambient pressure, such as atmospheric pressure; an electronic entity configured to determine a leak depending on the variations in the pressure ?P in the pressurised space and the variations in the ambient pressure ?Pext, the variations ?P, ?Pext being measured over a predetermined test time interval ttest by the first and second sensors, respectively.

Abstract: A testing device and method for improved detecting of fluid leaks considered important, for example, fluid leaks that would be external to a component or machine are disclosed. The testing device includes a conventional infinite fluid pressure supply source which supplies equal fluid pressure to a reference volume zone, a critical zone and an internal zone, the critical zone and internal zone may be positioned inside of a device being tested.
