| Abstract: | Thermocouple is one of the most common sensors used in temperature measuring system.Through the practical case,this article analyzes theoretically reasons of error generated in the temperature measuring process from thermocouple itself,compensating conductor,the secondary instruments,etc,and proposes corresponding countermeasures to improve the accuracy of thermocouple measuring,in order to provide theoretical guidance for testing temperature correctly and accuratly for the production process.The article is of practical significance. |
