Abstract: Mechanism of the technique of temperature measurement with a thermocouple is desctibed, and a new thermoelectric technique of temperature measurement- the intelligent and adaptive thermoelectric technique of temperature measurement is developed, combining two kinds of method of temperature measurement: the thermocouple method and the thermoresistance method, and using an intelligent software, stored in a single chip computer, thus widening the temperture range of the circumstance, to which a working thermocouple can adapt as well as heightening the accuracy of the temperature measurement.
