Seal and leak testing
Uson’s Optima vT Leak and Flow Tester uses built-in mathematical tools that could improve yields and quality for packagers seeking improvements and/or faster leak test cycle times while maintaining Gage R&R.
A product with four chambers can be tested concurrently and using the Optima’s math feature, summed to create a total, thereby providing both an individual and overall result, effectively cutting cycle time. Additionally, slope and intercept calculations along with averaging can easily be performed, using a host of other built in formulas. Optima’s built-in math streamlines production processes without putting an additional burden on the system controls—a task which takes much longer when performed manually or with spreadsheets.
The unit provides capabilities for vacuum decay tests, gage pressure decay leak testing, differential pressure decay leak tests, mass flow leak detection (including back pressure and differential), upstream and downstream cracking pressure, pressure rise tests, burst tests, laminar flow tests, force decay testing, and occlusion testing; state-of-the-art microcontrollers comparable to those used in the most sophisticated and demanding consumer electronics applications; 2 Channels with up to 4 sensors/channel, totaling up to 8 sensor inputs; simultaneous testing on all sensor inputs; fully customizable pneumatic controls; large easy-to-read full color touch screen display with intuitive user interface.
