Qual é a lei de temperatura intermediária dos termopares?

The intermediate temperature law of thermocouples means that in a thermocouple loop, if a conductor of a third material is connected, as long as the temperature of both ends of the third conductor is the same and the conductor is in a uniform temperature field, the thermoelectric potential generated by the thermocouple has nothing to do with the material and length of the intermediate conductor, but only with the temperature of both ends of the thermocouple.
For example, in a temperature measurement loop composed of thermocouples A, B and connecting wire C, as long as the temperature of both ends of connecting wire C (i.e., the cold end of the thermocouple) is the same, no matter what the material of wire C is or what temperature field it is in, the thermoelectric potential of the entire loop depends only on the temperature of the hot and cold ends of the termopar e não tem nada a ver com o fio de conexão C .
Esta lei fornece uma base importante para a aplicação prática de termopares, de modo que vários instrumentos, conectar fios e outros componentes intermediários possam ser conectados ao loop de medição da temperatura do termopar sem afetar a precisão dos resultados da medição, o que facilita bastante o uso de termopares e o projeto dos sistemas de medição de temperatura.}
