- Abstract:
- For the thermometric sensor calibration by the method of comparison in the range of 300°C to 1300°C a uniform temperature field should be maintained in a metal insert for each temperature level selected. The insert containing measurement pockets is located in a tubular electric furnace. The functionality of calibrating system pertaining to the time of measurement requires appropriate dynamic properties of electrothermal system. To get a suitable static temperature field in the measurement insert some real electrothermal systems of similar class were investigated and the results have been augmented with a 3–dimensional computer simulation of a tubular furnace with an insert. To obtain good dynamic properties during the calibration temperature changes a predictive controller of the insert temperature was used. The obtained accuracy enables precise calibration of industrial thermometric sensors.
