热电偶测量指示温度,在我们炼厂设计中司空见贯的是每个热电偶测量点都用二芯补偿导线与室内的温度指示仪相连接,有多少个热测点就有多少根二芯的补偿导线。随着技术的发展和社会主义建设事业的发展,必然向我们的设计工作提出是否有更好的方法。带着这个问题向上炼、石油五厂和兴平化肥厂进行了有关热电偶测量方面的调查。他们都在富有成效地使用着不同的方法。分别介绍如下: 石油五厂采用公共补偿导线法:如图1所示
Thermocouple temperature measurement instructions, in our refinery design is commonplace in each thermocouple measurement point with two-core compensation wire and indoor temperature indicator connected to the number of hot test how many two core Compensation wire. With the development of technology and the development of socialist construction, it is inevitable to propose to our design whether there is a better way. With this problem up to refining, Wuchang Wuchang and Xingping Fertilizer Factory conducted a survey of thermocouple measurements. They all use different methods productively. The following are introduced respectively: The Fifth Oil Plant uses the public compensation wire method as shown in Figure 1
