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 ΔP in the pressurised space and the variations in the ambient pressure ΔP, the variations ΔP, ΔPbeing measured over a predetermined test time interval tby the first and second sensors, respectively.
