Abstract
A leak detection system for testing a sealed product for leaks includes a test chamber, a pressure system that is operable to maintain a substantially constant pressure during a test period, and a leak sensor coupled to the test chamber via a first conduit and the pressure system via a second conduit. The test chamber of the leak detection system includes a receptacle dimensioned to receive the sealed product. Moreover, the test chamber includes a cover dimensioned to operably seal the receptacle at an initial internal pressure when placed into position with the receptacle. The leak sensor of the leak detection system is operable to permit gas flow between the test chamber and the pressure system via the first conduit and the second conduit. The leak sensor is also operable to obtain a value representative of total mass of the gas flow between the sealed test chamber and the pressure system during the test period. Furthermore, the leak detection system is operable to determine, based upon the value obtained for the total mass of the gas flow, whether the sealed product leaked an unacceptable amount during the test period.
