在整个工业中,对精密测温的要求越来越高。电站和石油化工等行业在生产现场安装了为数众多的电阻温度计和热电偶,这些测温元件往往要在现场进行精密分度。国际实用温标铂电阻温度计,S 型热电偶和光学高温计通常称为“工作标准”。这些温度计定期在国际实用温标(IPTS)的定义固定点和二级参考点上分度。然后以它们为标准,采用比较法分度工业感温元件和测温仪表。比较法分度时,
In the whole industry, the requirements for precision temperature measurement are getting higher and higher. Power plants and petrochemical industries in the production site installed a large number of resistance thermometers and thermocouples, these temperature components are often in the field for precision indexing. International practical temperature scale platinum resistance thermometer, S-type thermocouple and optical pyrometer commonly known as “working standards.” These thermometers are periodically indexed at defined fixed point and secondary reference points of International Practical Temperature Scale (IPTS). And then take them as the standard, adopts the comparative method to divide the industrial temperature sensing element and the temperature measuring instrument. When compared with the law,
