Automated leak test
The automated leak test is a test method by which, for
example, components are tested for their tightness against gaseous or liquid
media. However, an exact localization of the individual leak point at the test
item is not possible with automated methods. Rather, it can be seen that the
test piece has a leak. Conclusions about the possible extent or the magnitude of
the leak are also possible. Absolute density does not exist in principle;
rather, it is a matter of determining the leak rate.
Automated leak test with the test leak ATL01 (The device will no longer be available from 2024!)
With our test leak ATL01 you can test your complete leakage / flow
test device cyclically during production. The control can be carried
out in automatic or semi-automatic operation. All necessary connections for
remote control or adaptation to the pressure test line (test air conditions) between
the test part and the leakage / flow tester are available. Since the data can
only be processed by authorized persons using a key switch, the required
sequence parameters can be stored in the ATL01 by the installer in a fail-safe
manner.
Execution of the test procedure:
- During production, a test part is determined as OK.
- The same test part is subsequently checked again in the device. This time,
however, the ATL01 is switched on.
- In the ATL01 the leakage must be set to a
value above the permissible sealing limit. The following leakage test must now
have NOT OK as a result.
- In this case, the system operates correctly. Otherwise a defect is present
and the system has to be checked.
An alternative to the above-described sequence is the realization of an
automatically self-monitoring test device. The advantage: The test results of
the ATL01 as well as of the leakage / flow tester can be
transmitted to the higher-level controller and evaluated so that usable
measuring results are available. Inspection plans and protocols can also be
processed. The necessary data can be read and edited via the data interface
integrated in the front and a PC software.

leak testing with the ATL01? As a recognized manufacturer of leak detectors and leak
testing devices for various application fields, we are the right contact. We
