Achieve Maximize Efficiency and Productivity with CTS Test and Reclaim Systems

Vacuum Leak Test Systems

Vacuum leak testing is the principal leak test method for testing sealed parts that could have leakage from an external source into their housings and casings. Prime candidates for vacuum leak testing include:

  • Underwater sensors or housings
  • Outdoor electrical housings
  • Sealed components
  • Components associated with vacuum sources

Vacuum leak testing functions in a similar, but essentially opposite, manner as pressure decay testing.
Cincinnati Test Systems (CTS) designs and manufactures a full line of vacuum leak test instruments that utilize innovative technology to deliver reliable, repeatable solutions to leak testing challenges.

Why Use Vacuum Leak Testing?

In vacuum leak testing, the part or vessel being tested (the test piece) is connected to a pressure/vacuum line and placed in the test chamber. The chamber is closed and sealed, all supply valves are closed, and the test piece and the chamber are simultaneously evacuated via vacuum to a preset pressure level. Once the pressure has stabilized, any pressure change in the test piece is compared to pressure changes in the chamber’s reference volume. If the test piece does, in fact, leak, the pressure difference between the two will increase. This data is measured and recorded.

Compared to pressure decay testing, vacuum leak testing can provide better repeatability because it is less sensitive to environmental variables created by temperature changes. A vacuum leak detector often requires less time to reach a stable test pressure, is less susceptible to potential instability of tested parts, and offers shorter cycle times than tests in many pressure decay applications.
