Abstract
A temperature monitoring and control system for a glass sheet processing system includes a temperature sensor mounted at a preselected location in the system, a display, and a computer connected to the temperture sensor for periodically receiving a series of signals corresponding to temperature values transmitted by the sensor. The computer includes memory for storing selected values received from the temperature sensor and memory for storing one or more preselected threshold values. The computer also includes control logic for comparing the temperature values with one or more of the preselected threshold values, selecting and storing a set of those temperature values which satisfy a predetermined criteria, and displaying the set of temperature values as a profile taken along the length of the glass sheet in the direction of conveyance of the sheet through a glass processing system. The system preferably includes a data input device and provides the operator with the ability to program one or more of the threshold values. The system may also include an output to the power source of the furnace in the glass processing system for varying the power to the furnace, and control logic for comparing the stored temperature values with one or more preselected threshold values and transmitting a signal to vary the power supplied to the furnace as a function of the results of the comparison of the stored values with the preselected threshold values.
