Abstract
This project, titled “Enhanced Process Control Through Microcontroller-Based Parameter Monitoring,” aimed to retrofit a laboratory cryopump with advanced flow and temperature monitoring capabilities for its water cooling loop system. An older sensor array had been installed, but it lacked temperature monitoring and usable liquid flow data. The core objective was to enhance process control, data acquisition, and indicators for key parameters. The sensor array would also improve system performance and reliability. To achieve this goal, an HMI was programmed using LabView, and National Instruments Data Acquisition (DAQ) devices were utilized to integrate the sensors with a lab PC, ensuring proper data handling and control across a visual user interface. Alerts for high temperatures and low flow were installed on both the HMI and a physical panel to track system performance. Initial attempts with consumer-grade microcontrollers and sensors were found inadequate due to their hardware limitations and reliability. Consequently, the National Instruments DAQ system was selected for its superior ease of use, availability, and compatibility with existing lab infrastructure. The project’s success demonstrates the feasibility of modernizing older equipment with contemporary control and monitoring technologies, improving legacy lab equipment. The potential for scaling this design suggests broader applications across other systems in the lab, thereby enhancing overall operational efficiency and user-friendly system interfacing.
