The new hydrogen leak detector by ForTest allows to display the
leakage without having to make the immersion in water of the piece
to be tested, and without using any spray to detect the leak.
Intended both as a cycle that follows the normal leak test, either
as a separate workstation for repairs only, the new sniffer at
hydrogen allows in an easy, clean and fast way, the detection of the
precise point of the leakage, enabling to repair the fault in a much
faster and cleaner way.
It can be installed as an option on M8990
and M8960 equipments, combining then the leak test together with the
display of the leakage, or as an equipment that makes only its
localization, ideal then not only to find the ideal testing points,
but also to repair the pieces. The great measurement sensitivity
allows to detect leaks at a distance of already 5 cm., till arriving,
thanks to the automatic scale change, to the precise position of the
leakage, and to appreciate micro leaks of 1cc/h at a distance of few
millimeters. It is perfect both for particular pieces that cannot be
put into the water, either for simple ones, in order to avoid
cleaning or drying after the normal bubble test.
The system is composed by a central unit to set programs and test
cycles, and by a hydrogen manual sniffer to find the leakage. The
cycle is composed by a phase of piece emptying, in order to aspirate
all the air molecules contained in it and then by a phase of piece
pressurization with a hydrogen blend at 5% to detect the right
position of the leakage. The intelligent logic of the Led bar on the
equipment panel and of the multi-tone buzzer, allow the operator to
recognize immediately the precise location of the leakage. The low
presence of hydrogen in the blend (5% H2-95% N2-NOT FLAMMABLE) makes
testing safe and much more practical and clean than the classical
systems in water basin or with leak detector spray.
