Medical device and biotechnology product manufacturers can now obtain the USON Pressure Decay Leak Test Calculator– the first in a family of automated Uson NDT test calculators – to generate nearly instantaneous answers to ‘What If’ modeling of pressure decay leak testing variables and exact returns-on-investment from new eight-sensor concurrent leak testing technology.

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

  • 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, stabilisation, 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.

Uson leak detection equipment technical specialist Joe Pustka explained that this is the first of several automated calculators Uson will be making available in the coming months.

Pustka said; "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 — all of which Optima vT can be custom-configured to handle with maximum efficiency — 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 added; "Say, for example, a manufacturing engineer has fixed test pressures and parts volumes but wants to ask ‘What if we used eight-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."
