| Abstract: | In this paper, we introduce a thermocouple temperature measuring instrument based on microprocessor 8031, analysis the characteristics of the thermocouple temperature sensor, and bring up a new method, which is look-up twice, compensate the measuring error caused by the change of the thermocouple reference point's temperature. According to this method, the measuring error can be compensated automatically in the normal range of the reference point's temperature. |
