Abstract

The present invention provides a system for measuring temperature by using a thermocouple. The system includes a computer, a data acquisition board and a thermocouple. The data acquisition board includes a temperature transducer integrated circle for calculating a temperature of a cold-junction in the thermocouple; an A/D convertor for transforming analog signals of voltage created by the thermocouple to digital signals, measuring the voltage, and calculating errors in A/D channels and the cold-junction temperature; a microcontroller unit for correcting errors of the voltage and the cold-junction temperature. The computer includes a date acquisition unit for compensating the voltage and transforming the compensated voltage into temperature.
