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。
热电偶的种类及测温范围
淮安嘉可自动化仪表有限公司热电偶的种类及测温范围目前列在国际电工委员会推荐的8种标准热电偶如下。
1、铂铑10-铂热电偶（S型）。
适用于氧化气氛中测温，不推荐在还原性气氛中，短期可用于真空场合。
长期使用温度范围为0~1300℃，短期为0~1600℃。
2、铂铑13-铂热电偶（R型）。
适用场合同S型热电偶。
3、铂铑30-铂铑6热电偶（B型）。
适用于氧化气氛中测温，其主要特点为稳定性好，参考端温度在0~100℃时可不用补偿导线。
长期使用温度范围为0~1600℃，短期为0~1800℃。
4、镍铬-镍硅热电偶（K型）。
适用于氧化气氛中测温，不推荐在还原性气氛中使用。
测温范围决定于偶丝直径，一般为-200~1200℃（1000℃偶丝直径为1.5mm，1000℃为2.5mm，1200℃为3.2mm）。
5、镍铬硅-镍硅热电偶（N型）。
测温范围为0~1300℃，稳定性好。
6、镍铬-康铜热电偶（E型）。
适用于氧化及弱还原性气氛中测温，测温范围为-200~900℃。
7、铁-康铜热电偶（J型）。
适用于氧化及还原性气氛中和真空中测温，测温范围为-40~750℃。
8、铜-康铜热电偶（T型）。
适用于-200~400℃范围内测温，其主要特点是精度高、稳定性好、低温灵敏度高，价格低廉。
除了上述国际标准化热电偶外，还有适用于某些特殊测温场合和条件淮安嘉可自动化仪表有限公司的非标准化热电偶，如下所列。
1、钨铼3-钨铼25热电偶（WRe3/25型）。
根据美国ASTMEE-988-84标准，这种热电偶适用于惰性气体、氢气及真空下，测温范围为0~2200℃。
2、钨铼5-钨铼26热电偶（WRe5/26型）。
适用于惰性气体、氢气中测温，也可用于真空场合，测温范围为0~2200℃。
3、镍铬-金铁热电偶。
适用于0~273K低温范围的液氮、液氢介质。
4、非金属热电偶。
具有热电势大、熔点高等特点。
如石墨-碳化钛热电偶可在含碳和中性气氛中可测2000℃高温；碳化硼-石墨热电偶坚硬耐磨、耐高温、抗氧化，在600~2000℃范围内线性好且热电势大。
各型热电偶分度对照表
S型热电偶）铂铑10-铂热电偶铂铑10-铂热电偶（S型热电偶）为贵金属热电偶。
偶丝直径规定为0.5mm，允许偏差-0.015mm，其正极（SP）的名义化学成分为铂铑合金，其中含铑为10%，含铂为90%，负极（SN）为纯铂，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具有准确度最高，稳定性最好，测温温区宽，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，适用于氧化性和惰性气氛中。
由于S型热电偶具有优良的综合性能，符合国际使用温标的S型热电偶，长期以来曾作为国际温标的内插仪器，“ITS-90”虽规定今后不再作为国际温标的内查仪器，但国际温度咨询委员会（CCT）认为S型热电偶仍可用于近似实现国际温标。
S型热电偶不足之处是热电势，热电势率较小，灵敏读低，高温下机械强度下降，对污染非常敏感，贵金属材料昂贵，因而一次性投资较大。
（R型热电偶）铂铑13-铂热电偶铂铑13-铂热电偶（R型热电偶）为贵金属热电偶。
偶丝直径规定为0.5mm，允许偏差-0.015mm，其正极（RP）的名义化学成分为铂铑合金，其中含铑为13%，含铂为87%，负极（RN）为纯铂，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具有准确度最高，稳定性最好，测温温区宽，使用寿命长等优点。
其物理，化学性能良好，热电势稳定性及在高温下抗氧化性能好，适用于氧化性和惰性气氛中。
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。
1967年至1971年间，英国NPL，美国NBS和加拿大NRC三大研究机构进行了一项合作研究，其结果表明，R型热电偶的稳定性和复现性比S型热电偶均好，我国目前尚未开展这方面的研究。
R型热电偶不足之处是热电势，热电势率较小，灵敏读低，高温下机械强度下降，对污染非常敏感，贵金属材料昂贵，因而一次性投资较大。

钨铼热电偶
一、钨铼热电偶是最成功的难熔金属热电偶，也是可以测至1800℃以上的工业热电偶中性能最佳的热电偶。
随着高新技术的发展，钨铼热电偶的应用将越来越广泛。
◆钨铼热电偶的特点：热电极丝熔点极高（3300℃）、强度大。
热电动势大、灵敏度高、共热电动势率为S 型热电偶的两倍，B型三倍。
极易氧化。
价格便宜，仅为S型热电偶的1／3.◆钨铼热电偶的说明：钨铼热电偶的理想测温范围为0-2300℃，最佳测温为1300-2000℃。
其结构为单管或双管，保护管为精细特纯刚玉，纯钼管，金属陶瓷，钽管，钨管等，抽真空后填充特高温绝缘材料，经久耐用，广泛适用于真空、氢气、氮气等还原气氛和惰性气体保护炉。
二、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。
