钨铼合金热电偶可以代替铂铑热电偶测温应用。钨铼热电偶的牌号有W/WRe25、WRe5/WRe20、WRe3/WRe25、WRe5/WRe26等。被纳入协会或国家标准的较成熟的牌号为WRe3/WRe25,WRe5/WRe26。见美国ASTM E696-79标准。 我所研制的WRe3/WRe25热电偶,根据多年来积累的分度数据,经电子计算机作热电势和温度的分度曲线和美国ASTM E696-79标准数据作图比较,其偏离度<±1％。
Tungsten Rhenium alloy thermocouple platinum thermocouple thermometer can be used instead of temperature measurement applications. W rhenium thermocouple grades W / WRe25, WRe5 / WRe20, WRe3 / WRe25, WRe5 / WRe26 and so on. The more well-established brands that are included in the association or national standards are WRe3 / WRe25, WRe5 / WRe26. See American ASTM E696-79 standard. The WRe3 / WRe25 thermocouple developed by me, based on the graduation data accumulated over the years, is compared with the data of American ASTM E696-79 indexing curve by the thermocline and temperature of the computer. The deviation degree is less than ± 1% .
