Abstract
A leak detection system includes a chamber support including a chamber supported by a frame. A trace gas supply supplies a trace gas mixture to a first volume defined between the chamber and a test part. A test part support includes an adapter supported by a frame and configured to mate with the test part and to define a second volume between the test part and the adapter. A seal plate surrounds the adapter and seals with the chamber. One or more inlets are in fluid communication with the second volume. N outlets are in fluid communication with the second volume. N fans create a second vacuum pressure in the second volume, supply gas to the one or more inlets and receive gas from a respective one of the N outlets. N gas sensors sense trace gas in the gas received from a respective one of the N outlets.
