Industrial Process Control
Stewart Engineers' Industrial Process Control What is Industrial Process Control Extremely accurate industrial process control is the key to strong float glass operations. Glass making demands precision. For example, the glass level in the furnace is often controlled within +/- 0.005 inches, which canal temperature is typically controlled within +/- 1 degree C Analog outputs are controlled by Proportional-Integral-Derivative (PID) loops. The proportional constant determines the amount of response to a deviation from the setpoint. The integral portion resets the response at a given time interval, and the derivative is used for slow loops that adjust the output based on the slope of the deviation from the setpoint. Why Stewart Engineers' Industrial Process Control Knowledge of the control process is key for accurate loop timing and therefore accurate and repeatable control. Stewart Engineers' expertise in the glass industry allows for creative solutions and more precise contr...
