Load Cell Controls Stepper Motor to provide zero pressure on connecting flange.
Implementation
Redundant Cryo Bench Cooler for India Space agency. Used to test satellite components in a vacuum chamber. Some tests can run for months and requires 100% uptime all components were built as dual redundant, including PLC I/O and power supplies.
Dual Turbo Pumps evacuate the chamber attached to the flange. During pump out and cool down no strain can be placed on the flange a load cell connects to an Oriental Motor Stepper and maintains zero strain.
Systems are programmed in Visual Basic with MS Access process and datalogging. Databases are periodically replicated to back-up storage and data servers.
Benefits
- Automated pump down and vent
- Automated process data collection
- Data files are accessible from any workstation via wireless Ethernet
