一、前言在生产或科研的测温和控温过程中,经常会发现人们对热电偶都是顺手拿来使用,大都不去过问热电偶的结构和装配的情况,更不去过问热电偶在测温和控温过程中的动态性能。常把测温和控温过程中发生的较大的误差和失控现象,全归罪于自动化仪表不好。结果把仪表打开,调来调去,问题还是得不到解决。另一方面,因为人们不重视这些自认为是没有理论性的“小问题”,在生产厂中,在制造和装
First, the preface In the production or research temperature and temperature control process, often found that people are readily available to use the thermocouple, most do not go to the thermocouple structure and assembly, not to ask the thermocouple at Dynamic performance during temperature measurement and temperature control. Often the temperature and temperature control process occurred in the larger error and out of control phenomenon, blame the automation instrument is not good. The results of the instrument to open, transfer transferred to go, the problem still can not be solved. On the other hand, because people do not attach importance to these “small problems” that they consider to be without theory, in manufacturing factories,
