近年来,在我国工业部门中广泛地应用BA_1、BA_2分度的云母和玻璃支架的工业铂热电阻元件,在-200℃～+500℃温度范围内,进行温度测量和调节。这两种类型的元件制造工艺比较复杂,支架材料来源也不易。有些工业部门又特别注意铂热电阻元件机械性能的稳定性和可靠性。1968年国际实用温标(IPTS—68)中规定13.81K到630.74℃温度区间标准铂电阻温度计是实现温标的标准仪器,工业铂热电阻元件也将从现行规定的使用温度上限500℃延申到650℃。综上所述,云母和玻璃支架的铂热电阻元件要达到这些要求会有一定的困难,为此,寻找新的支架材料制造铂热电阻元件就很有必要。我们经过几年来的试制,
In recent years, widely used in industrial sectors in our country BA 1, BA 2 graduated mica and glass bracket industrial platinum RTD components in the temperature range of -200 ℃ ~ +500 ℃, temperature measurement and regulation. These two types of component manufacturing process is more complex, scaffold material source is not easy. Some industrial sectors pay particular attention to the stability and reliability of the mechanical properties of platinum RTD components. 1968 international practical temperature scale (IPTS-68) provides 13.81K to 630.74 ℃ temperature range Standard platinum resistance thermometer is the standard equipment to achieve temperature scale, industrial platinum RTD components will also be extended from the current use of the maximum temperature limit of 500 ℃ to 650 ℃. To sum up, it is difficult to meet these requirements for the platinum RTD components of mica and glass brackets. Therefore, it is necessary to find new scaffold materials for the manufacture of platinum RTD components. After several years of trial production,
