According to Spitzig, the YSI products offered both short term ease of installation and long term benefits. “From the start, the YSI solution was an easy choice,” says Spitzig. “The simple one-cable design – being able to run one cable that provides both power and data-transfer made so much sense. The system enables the addition of more probes or instrumentation at any point down the road, with minimal interruption to our day-to-day operations.” The new network also enables the Adelaide plant to tie in complimentary, non-YSI products without any rework or major adjustments. It’s essentially plug and play. Back at Vauxhall, the installation of the online monitoring probes in strategic locations will enable the monitoring of key parameters as often as necessary, allowing the plant to maintain compliance as well as optimize process efficiencies. Much of the new instrumentation provides the ability to set alarms when certain parameters reach pre-determined min/max levels.

Results As with any upgrade to an existing facility, it is essential to keep the plant running smoothly during the renovation and upgrade process. The interference with plant operations during installation was minimal with the single-cable system, which incorporated some of the existing components within the plant but also deployed current, up-to-date technology. Once the conduit, instrumentation and probes were installed, the new technology was tied into the existing plant SCADA system via Profibus, which now provides plant personnel with a clear picture of the online monitoring activity.
