Critical Air System Pressure Controller

Hespe, Morgan
The Critical Air System Pressure Controller is a type of industrial/commercial controller designed to optimize performance and monitor operation of an air pressure system with two compressors. In some critical systems, redundancy is a necessary characteristic of the system. Because of this, critical air pressure systems often employ multiple compressors. This project uses a microcontroller, associated circuits, and transducer to alternate compressor starts ensuring equal starting wear on and run time for the motors. The controller optimizes performance by operating the additional compressor when needed to increase system capacity and quicker recovery versus simple alternating designs. Compressor operation is monitored to detect weak motors or mechanical failures within the system. The control user can select system set points via dip switches. The corresponding set points and current system pressure are displayed on seven-segment LED displays.
