ABSTRACT:
A leak testing control assembly for a leak testing system of a type that cooperates with a test part interface that is coupled with a test part. In a broad aspect the leak testing control assembly includes a working fluid generator for applying a working fluid having a fluidic pressure to a test part. A flow controller assembly is coupled to the working fluid generator. The flow controller assembly includes a flow controller element for controlling the flow rate of the working fluid. A pressure level measuring element is positioned relative to the test part for measuring the fluidic pressure. A control system is coupled to the flow controller assembly and the pressure level measuring element. A user interface is coupled to the control system for providing user interaction with the leak testing control assembly. During operation, the control system 1) facilitates application of the fluidic pressure at a selected relatively constant flow rate; and, 2) interprets the value of the fluidic pressure, after the application of the fluidic pressure at the selected relatively constant flow rate, to determine whether the test part is free of leaks.
