NEW TECHNOLOGY APPLIED:
Allen Bradley SLC 500
Rockwell RSView 32 SCADA System

SCOPE OF WORK:
Staneco Corporation designed a control system to do high pressure testing for Trans-oceanic fiber-optic repeaters. The repeaters were put into a high pressure vessel. The outside of the vessel was pressurized to 10,000 PSI with a mixture of air and helium. The inside was monitored using a helium leak detector. Multi-stage pumps had to be used to attain the required pressure; this pressure had to be held for a selected time. Since the plastic content in the repeater could be damaged if the pressure changed too quickly, the pressure had to be reduced over several hours.

PROJECT OUTCOME:
By utilizing the new control system, repeaters could be tested more quickly allowing production to meet increased sales demands.
