Compared to pressure decay testing, vacuum leak testing can provide better repeatability as 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.

Leaks, even when they are small, can have a significant impact on the performance of a part or component or cause equipment to fail. Cracks and faulty seals are often the cause of these leaks, they can often be detected by conducting vacuum testing on components prior to manufacturing.

Using a vacuum leak tester 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 test procedures include:

The other difference between pressure decay and vacuum decay testing is related to the pressure differential that is created across the leak path and forces created on the part. When conducting vacuum decay testing, the greatest differential that can be created is related to atmospheric pressure and typically vacuum decay testing is not conducted at full vacuum. Pressure decay testing, however, can create a much greater differential across the leak path because of the ability to use compressed gases (caveat: the higher the pressure, the longer the stabilization time required).

Vacuum leak detection functions in a similar, but essentially opposite, manner as pressure decay testing. During a pressure decay test the part is pressurized with dry, clean compressed gas (dry Nitrogen or shop air). During this fill cycle pressurized gases heat up, requiring a stabilization period necessary to dissipate the heat for stable leak testing. During a vacuum decay test, a regulated vacuum source is applied to the part, any thermal event that occurs during this operation is highly reduced and requires less stabilization time prior to conducting the leak test cycle.

Multi-channel, and multi-functional, 1,2,3,&4 channel vacuum leak detector with a small footprint for benchtop use or industrial wall mounted enclosures. Features easy operator setup and auto calibration. Standard test pressure ranges are -14.5, -2, -0.1 to 4” HG, 0.5, 2, 10, 30, 100, 200, 400, 500, or electronic regulation (PSIG).

When extremely high pressures are needed to conduct a pressure decay test, CTS suggests conducting a vacuum decay test on the part placed in a test chamber, the part is pressurized with high pressure and vacuum is applied to the test chamber as a vacuum decay testing is conducted. This technique allows the thermal event to occur within the part but does not affect the outside vacuum chamber leak test to accommodate repeatable testing results.
