Development of Automatic Control System and Data Acquisition System for anEnvironmental Chamber

摘要

The objectives of this project were to design, fabricate, and install automaticcontrol and data acquisition systems on an environmental chamber. The control system maintains the chamber pressure to within 1 mmHg, temperature to within 1 F, and humidity to within 3% relative humidity, using a modern distributed process control system. The data acquisition system records data, using a minicomputer that is compatible with existing DEC equipment. This report contains information from the final system specification and configuration item development specification for each system.
