热电偶、热电阻是在炼油化工生产过程的温度测量中使用面最广、使用量最大的产品之一。这两类产品过去是以仿制为主,它们没有统一的技术条件,也没有统一的基本参数,因此给生产和使用带来了很多不便。例如各制造厂生产的产品规格不统一,不能做到互换,产品的质量也提不高。为了改变这个局面,一机部委托上海工业自动化仪表研究所组织了热电偶、热电阻的统一设计工作。在各参加单位的努力下,经过调研、制
Thermocouple, RTD is one of the most widely used and most used products in the temperature measurement of the refining and chemical production process. These two types of products used to be based on imitation. They do not have uniform technical conditions and do not have uniform basic parameters, which brings a lot of inconveniences to production and use. For example, the manufacturer’s product specifications are not uniform, can not be exchanged, the quality of the product is not high. In order to change this situation, a machine department commissioned Shanghai Institute of Industrial Automation Instrumentation organized a unified design thermocouple, thermal resistance. In the efforts of participating units, after research, system
