USON develops automated calculator for pressure decay leak testing

The USON Pressure Decay Leak Test Calculator can be used by manufacturing and automated process engineers to generate nearly instantaneous answers to “What If” modeling of pressure decay leak testing variables and exact returns-on-investment from new 8-sensor concurrent leak testing technology.

These automated calculators are available at no charge by sending in an email request.

Some of the variables that the USON Pressure Decay Leak Test Calculator enables engineers to manipulate includes:

-Pressure Ranges (PSIG)
-Leak Rate Target
-Number of Concurrent Pressure Decay Sensors in Use (up to 8 with USON’s Optima vT Leak and Flow Tester)
-Customisation of test cycle times, including all stages of fill, stabilization, test time, and total)
-Part/test volume
-among other specifications that vary from application to application, and that Optima vT Leak and Flow Testers can be custom configured for maximise efficiency.

Joe Pustka, USON Leak Detection Equipment Technical Specialist, explains that this is the first of several automated calculators USON will be making available in the coming months.

Pustka comments, “Pressure decay leak tests are only one of the dozen types of tests that the unique Optima vT Leak and Flow Tester performs. That gives you nearly half a billion different permutations of how you could use this technology if you are looking at test methodology alone.

"When you add in the innumerable possibilities for part sizes, shapes, volumes, test pressures, acceptable leak rates, pneumatic controls affecting cycle times, and so forth, it becomes apparent why we are creating these automated calculators for our customers and all those who are looking at ways to constantly improve test processes, efficiencies and throughput.”

Pustka continues, “Say, for example, a manufacturing engineer has fixed test pressures and parts volumes but wants to ask ‘What if we used 8-sensor concurrent leak testing instead of simple two-channel dual testing?’

"He or she could calculate throughput improvements in seconds and in turn get an exact return-on-investment from trading up to Optima type leak detection technology.

"As another example of how these calculators can be used, design engineers grappling with effects of subassembly re-designs affecting test volumes will similarly get one-click answers to various ‘What If’ modeling scenarios.”
