补充资料:温差电偶材料
      用于制作温差电偶的材料。温差电偶是一种广泛用于测量和控制温度的器件。它由两种不同的导体连接成回路,并将两接头置于不同温度之中而成。这时回路中将产生电动势,称为温差电动势。温差电动势只与选用的材料及两端的温度差有关,与材料的长短、粗细无关。材料选定后,温差电动势只是温度差的函数。
  
  为保证温差电偶灵敏、可靠,对材料的性能要求主要有:①使用温度范围广。在此范围内,材料有足够大的温差电动势和温差电动势率S。S定义为温差电动势随温度的变化率,即S=dE/dt。它表示温差电偶的测温灵敏度。②温差电特性稳定,复现性好。③电导率高,电阻温度系数低。④化学稳定性好,抗氧化。⑤有良好的机械加工性能。
  
  温差电偶材料按工作温度范围可分为高温类(1600~2300℃),中温类(600~1250℃,0~600℃),低温类(40~300K)。高温类材料主要有钨、铼、铱、铑、铂。中温类材料主要有镍铬、镍硅、考铜(铜、镍、锰合金)。低温类材料主要有镍铬、镍铝、铜和康铜(铜55%,镍45%)、镍铬和康铜等。
