Sentinel 3520 — A Reliable, Repeatable System for Leak Testing Large Parts
When you’re struggling to balance accuracy, cycle time and Gage R&R for a complex leak test, the Sentinel 3520 is up to the challenge. It is a pressure decay and mass flow instrument particularly suited to large parts such as EV batteries, variable volume parts, and parts requiring temperature and other compensation— all while delivering speed, accuracy, and repeatability. This instrument offers advanced configurability using CTS partner company Sciemetric’s digital signature analysis software.
Performing in the Most Challenging Leak test Situations
Many manufacturers struggle with leak test station accuracy, cycle time, and Gage R&R, particularly when faced with complex leak test requirements like large volume leak test, variable volumes, multi-cavity parts, low leak rates, and pressure stability. It is a top choice for EV battery testing.
These test scenarios require a precise balance of pressure control, flow range and fill rate to get an accurate reading and meet cycle time requirements, which the Sentinel 3520 delivers.
- Testing large parts, up to 1000L
- Testing variable volume parts with multiple cavities
- Uniquely compensating for temperature, atmospheric and barometric fluctuations affecting test
- Achieving balanced accuracy, cycle time, and Gage R&R

Six reasons to use the CTS Sentinel 3520 for large part leak testing
Advanced Leak Test Data and More Accurate Defect Detection Using PSV™ Software
The Sentinel 3520 is controlled by a sigPOD running Sciemetric’s PSV™ (process signature verification) software which measures thousands of datapoints during each test for more accurate pass/fail decisions. The sigPOD also allows you to access visualized control charts, histograms and other SPC tools right at the station.
There are various options to export, store, and report on your data. The CTS QualityWorX Datahub allows you to consolidate data by part number, including process signatures from up to 5 test stations. It includes a license to Sciemetric Studio software, a manufacturing analytics software that lets you visualize and analyze test data. For a broader solution that collects data from more stations, take a look at QualityWorX and Sciemetric Studio.
