Solar Atmospheres Creates Tutorial on Understanding PID Control As Applied to Vacuum Furnace Performance
Solar Atmospheres, Inc. has written a technical white paper on understanding and proper usage of PID parameters as they relate to controlling vacuum furnace temperature. This tutorial will assist furnace engineers and operators to better understand and properly use the functions of a PID Controller and thereby obtain improved temperature control, particularly in program ramping and minimizing temperature overshoot, required for AMS 2750D.
This paper describes how to both manually and automatically set PID values for various temperatures of operation. It highlights how to establish better results especially in the lower temperature ranges of operation (300 - 1500oF) and also how to better understand instruments that have the Autotuning feature.
Solar Atmospheres is one of the largest privately owned commercial heat treating and brazing companies in the USA with three heat treating plants, two in Pennsylvania and one in California. Also included in the Solar family of companies is Solar Manufacturing Inc., a vacuum furnace manufacturer, and Magnetic Specialty a manufacturer of heat treating furnace power supplies and specialty transformers for general industry.
