<p>A method and system for testing the accuracy of a thermocouple probe exposed to liquid steel having a temperature of between about 2700 °F and 3000 °F is provided that includes the step of measuring the rate of change of the temperature readings of the probe after a temperature of at least 2000 °F is read, and comparing the measured rate of change with a standard rate of change obtained from a properly operating probe. Both the method and the system are advantageously capable of determining whether the temperature readings of the thermocouple in use in a steel production plant are accurate without the need for comparative readings from other thermocouple probes.</p> |
