CENTENNIAL HONORS COLLEGE Western Illinois University Undergraduate Research Day 2015 Poster Presentation Controller Design to Operate One 4 Zone Furnace Kyle Janiak Faculty Mentor: Brian Bellott Forensic Chemistry The design and construction of a controller that can operate one 4 zone furnace will be discussed. Having a different number of zones in a furnace allows an experiment to be designed where a temperature gradient can be used. This allows for a different crystal growth technique than those currently used in the Bellott research group. The purpose for building the controller is cost. A commercially built controller which won’t exactly fit our needs will cost approximately $2000 dollars. The controller we have built cost the research group $250 dollars.
