Application Note: Speed Up Your Leak Testing!
As productivity
and quality requirements for manufacturers continue to increase, high
performance helium leak detectors become a key element of maintaining
production throughput and keeping costs under control - as automated
leak detection processes are often a production bottleneck. Production
and testing teams must be able to respond to sudden peaks in utilization
levels - without additional investment.
For helium leak
testing applications, the standard leak testing method used today,
INFICON offers two innovative systems - Modul1000 and LDS2010 - that
are optimized for rapid leak test procedures and high uptime. In particular,
the LDS2010 has industry-leading features for automated leak testing
processes:
- Helium pumping
speed (a key measure for short signal
response time and testing efficiency)
of 5 liters/second makes the LDS2010
many times more efficient that most ‘multi-purpose’ leak
detectors and the production leak detector
with the highest pumping speed in the
world
- Modular design
of the LDS2010 allows mounting of the
mass spectrometer close to the vacuum
test chamber to minimize flow rate loss
due to long vacuum lines; the control
electronics can also be integrated
in the system control cabinet - up
to 10 meters (33 feet) away
- Two opposing
performance attributes, maximum inlet
pressure and maximum sensitivity, can be variably adjusted to the
actual operating pressure
In addition to
delivering quick results, the Modul1000 is an excellent solution for
integration into small test benches, and functions as an overall system
controller for smaller jobs. It can also be easily integrated into
larger leak testing systems, thanks to several communication interfaces.
The system also features a wide detection range: from 0.1 to <5 X 10 ^-12 mbar l/s and its
compact outer dimensions enable installation into older test systems
to maximize productivity levels.
Protecting Your
Uptime
In helium leak detectors, the filament located in the ion source
can burn up when it comes into contact with oxygen, caused by pressure
bursts due to unclean chamber gaskets or broken components. This is
why conventional ion sources are considered consumable parts that must
be replaced regularly. To minimize costly unscheduled downtime and
maintenance expenses, INFICON developed an extremely robust yttrium/iridium
cathode that comes with a three-year replacement guarantee, regardless
of the number of hours of operation.
