Seal (O ring)
The tightness test is performed in the test chamber
2
. The deformation
sensor
1
and watch support are located inside the test chamber. When
the test procedure is started, the bell cover closes so that it rests
against the seal
3
. This ensures that the test chamber is sealed. The
pressure required for the test can now be built up and maintained in the
test chamber.
The pressure is built up by means of a compressor connected to the
device inside the test chamber
2
. The vacuum is generated by a Venturi
valve integrated in the device and the connected compressor.
