The SEAVA ®Lab system
provides air cap certification in a compact and
portable device. The system is intended for use in
maintenance shops and laboratories.
The air velocity is measured by a proprietary
multi-point air velocity probe. An indexer is used
to position the air velocity probe at preset
intervals in front of the applicator. Two flow
meters measure mass air flow and pressure to each
port of the paint gun (fan and atom). Finally,
proprietary PC-based software compiles data from the
sensors, controls the indexer and air supply, and
compares the data to a master profile and preset
limits to determine if the air cap is acceptable.
The test data is stored in the PC as a database for
future reference or comparison. Each test is time
stamped and dated, and the user may assign a name or
serial number to each air cap being tested. Users
can create master data sets to be used as the
standard for future tests. All files may be exported
to Excel for further analysis, or as a JPEG image
for E-mailing to colleagues.
When a user creates a master data profile they can
specify the number of tests to be taken, the
distance between test stops, and the size of the
area to be tested. Air supply pressure and air flow
can be manually adjusted before each test, and both
values for each port are tested for consistency
during each test.
