2. 钨铼热电偶分度号的解释说明2.1 钨铼热电偶的基本原理钨铼热电偶是一种常用的温度测量仪器,它利用了材料在温度变化时产生的热电势差来推断温度。

根据塞贝克效应和查伯雄效应,当两种金属或合金在不同温度下连接形成闭合回路时,会产生热电势差。

钨铼热电偶由钨和铼两种金属或合金组成,其工作基于钨和铼之间的热电势差。

2.2 钨铼热电偶的组成与特点钨铼热电偶由外保护管、隔离绝缘管、热敏部件(即钨/铼导线)等组成。

外保护管起到保护及隔离环境与测量对象之间的作用,隔离绝缘管则用于防止环境条件对测量结果的影响。

而钨/铼导线则是构成整个钨铼热电偶回路的关键部分。

其特点包括:1. 高温性能:由于使用了钨和铼这两种高熔点金属或合金,钨铼热电偶可以在高温环境下进行精确测量。

2. 耐腐蚀性:钨和铼具有良好的耐腐蚀性能,在一些化学和高温介质中都能保持稳定的工作状态。

3. 快速响应:由于钨铼热电偶导线本身是极细且灵敏的,因此它可以快速地反应温度变化并提供准确的测量结果。

2.3 钨铼热电偶的工作原理和应用领域钨铼热电偶的工作原理基于材料之间的热电势差。

热电偶各分度号的化学元素及其简介

热电偶各分度号的化学元素及其简介

热电偶各分度号的化学元素及其简介(1)铂铑10-铂热电偶(S型)铂铑10-铂热电偶(S型热电偶)为贵金属热电偶。

其正极(SP)的名义化学成分为铂铑合金,其中铑为10%。

负极(SN)为纯铂,含铂为90%,故俗称单铂铑热电偶。

该热电偶长期最高使用温度为1300℃,短期最高使用温度为1600℃。

S型热电偶在热电偶系列中就有准确度最高、稳定性最好、测温区宽,使用寿命长等优点。

它的物理、化学性能良好,热电势稳定性及在高温下抗氧化性能好。

适用于氧化和惰性气氛汇中。

S型热电偶不足之处是热电势、热电势率较小,灵敏度低。

高温下机械强度下降。

对污染非常敏感,贵金属材料昂贵,因为一次性投资较大。

(2)铂铑13-铂热电偶(R型)铂铑13-铂热电偶(R型热电偶)为贵金属热电偶。

其正极(RP)的名义化学成分为铂铑合金,其中铑为13%。

负极(SN)为纯铂,含铂为87%,长期最高使用温度为1300℃,短期最高使用温度为1600℃。

R型热电偶在热电偶系列中就有准确度最高、稳定性好、测温区宽,使用寿命长等优点。

它的物理、化学性能良好,热电势稳定性及在高温下抗氧化性能好。

适用于氧化和惰性气氛汇中。

由于R型热电偶的综合性能与S型热电偶相当,在我国一直难于推广。

除在进口设备上的测温有所应用外。

国内测温很少采用。

R型热电偶不足之处与S型热电偶相同。

(3)铂铑30-铂铑6 热电偶(B型)铂铑30-铂铑6热电偶(B型热电偶)为贵金属热电偶。

热偶丝规定为0.5mm,其正极(BP)的名义化学成分为铂铑合金,其中含铑量为30%,负极(BN)也为铂铑合金。

含铑量为6%,故俗称双铂铑热电偶。

该热电偶长期最高使用温度为1600℃,短期最高使用温度为1800℃。

B型热电偶在热电偶系列中具有准确度高、稳定性好、测温区宽,使用寿命长、测温上限高等优点。

适用于氧化和惰性气氛中,也可短期用于真空中,但不适用于还原性气氛或含有金属或非金属蒸汽气氛中。

B型热电偶一个明显的有点是参考端不用补偿导线进行补偿,因为在0-50℃范围内热电势小于3µV。

wre5-wre26钨铼热电偶

wre5-wre26钨铼热电偶产品说明:钨铼热电偶的特点是:热电极丝熔点高(3300℃),蒸气压低,极易氧化;在非氧化性气氛中化学稳定性好。

电动势大,灵敏度高,最主要还是价格便宜。

目前测量1600℃以上的温度,多采用非接触法,但是,该种方法的误差较大,如用接触法则能准确地测出真实温度。

在高温热电偶中,贵金属热电偶价格昂贵且最高温度也只能在1800℃以下,而钨铼热电偶不仅测温上限高,而且稳定性好,因此,钨铼热电偶在冶金、建材、航天、航空及核能等行业都得到广泛应用。

我国的钨资源丰富,钨铼热电偶价格便宜,可以部分取代贵金属热电偶(铂铑热电偶),它是高温测试领域中很有前途的测温材料。

它的最高使用温度可达到2800℃,可是,在高于2300℃时,数据分散。

因此,使用温度最好在2000℃左右。

钨铼热电偶极易氧化,适于在惰性或干燥氢气中使用,或用致密的保护管使其与氧隔绝才能使用。

不能用于含碳气氛(如在含碳氢化合物的气氛中使用,温度超过1000℃即受腐蚀)。

钨或钨铼在含碳气氛中容易生成稳定的碳化物,以致降低其灵敏度并引起脆断,在有氢气存在的情况下,会加速碳化。

钨铼热电偶抗氧化问题一直是国内外学者所关注的课题,并致力于研究解决。

我公司采用了国际先进制做工艺,成功研制开发了装配式高温高压钨铼热电偶,该产品的测温范围为0~1800℃,广泛用于冶金、焦化、化工窑炉、热处理、玻璃等行业,它具有精度高,价格低、性能稳定、不受工作环境气氛的限制等优点,是代替铂铑热电偶的理想产品。

我公司生产的钨铼热电偶已在很多单位广泛应用,其性能达到国外同类产品水平。

其技术指标如下:1、分度号:W-Re3/25,W-Re5/262、测温范围:0~1800℃3、测温精度:< ± 1% t;< ± 0.5% t4、时间常数:≥180 s5、绝缘电阻:> 5MΩ6、规格尺寸:300,500,750,1000,1100(mm)钨铼钢水快速测温热电偶是专为测量钢水、铁液及其它金属熔体温度而设计制造的,它具有体积小,热响应速度快、准确度高、价格低等优点。
