Abstract
A system for detecting a leak in a part having an interior cavity and at least one opening open to the interior cavity in which the interior cavity is pressurized with a preselected gas. The part is positioned within the test chamber while a carrier gas flows across the pan so that the carrier gas becomes intermixed with the preselected gas, if any, escaping through leaks in the pan. The gas flows directly through a turbulator which ensures homogenous mixing of the carrier gas and preselected gas, if present, and a baffle then converts the turbulent gas flow to a laminar gas flow. A gas sensor then detects the presence of the preselected gas in the laminar gas flow, indicative of the leak in the pan, and generates an appropriate output signal indicative of the presence of a leak in the pan.
