 Product Briefing Outline: Zellweger
Analytics has announced a major upgrade
to its MDA Scientific "Vertex" system - a
multi-point toxic gas monitoring system for
semiconductor fabrication.
Problem: New diagnostics and hardware have been incorporated for
monitoring redundant system power supplies, ensuring continuous
availability of the installed back-up. New diagnostics have also been
added to the pneumatic system for the identification of any problems in
the site exhaust lines. Gas detection performance has been enhanced
with the addition of a system vacuum valve for more stable airflow and
built-in pump monitoring for reduced maintenance. Pyrolyzers - used to
detect complex species such as nitrogen trifluoride (NF3) - have a more
efficient heating element for faster warm-up times and an improved
system power factor.
Solution: It consists of a network of up to 72 fixed point Chemcassette
colorimetric sensors and a powerful compact computer-based
touch-screen control unit. The system provides high sensitivity,
virtually crossinterference-free detection and clear physical proof of
an event. System improvements include a twin-drive highspeed control
computer, upgrades to the air flow sampling system and a new design of
the (RFID) tags for foolproof identification of Chemcassette tapes.
The new double hard-drive computer system provides a complete mirror of
the interactive operating system and data-logging capability for up to
72 separate zones, for complete redundancy. In the event of a drive
failure, the system switches seamlessly to the back-up drive, with no
loss of data or operating settings. For maintenance purposes, the
drives are ‘hot-swappable', ensuring continuous system availability,
protected by key access. Microprocessor speed has been increased from
700MHz to 2.6GHz in the new version.
Applications: Continuous monitoring of highly toxic gases.
Platform: RFID Chemcassette tags have been further developed and
simplified with a new self-alignment system for even better
reliability. The foolproof method ensures improved safety and
confidence in the availability of critical monitoring applications.
Existing users can access all upgrades through an attractive service
upgrade package.
Availability: 2004 onwards
