I'm getting ready to build my own cylinder leakdown tester through average parts found at local hardware stores and so forth. But the whole concept of the measurment of air percentage lost has me confussed.
The tester is required to be set at a desired psi using a regulator. Then a quick connect is supplied to the hose within the cylinder being tested. If my compressor is set at 120 psi and I set my gauge to test for 100 psi i'm going to inject 100psi continuesly into the cylinder. Regarless if its leaking my compressor will kick on and continue to compress air into the cylinder. So how am I supposed to measure the percentage of air lost if my compressor is going to keep 100psi within the line?
Yeah doing a leakdown test will allow you to hear the probably cause but I also want to see the percentage or amount of air lost. If someone can elaborate on the theory of how this test works I would greatly appreciate it. I know the process is simple I'm just lost on how it actually reads percentage of air lost.
