热电偶

热(re)电(dian)偶(ou)(ou)(ou)是测(ce)量温(wen)度(du)(du)的(de)(de)(de)装(zhuang)置(zhi),它由端部紧密(mi)连接(jie)的(de)(de)(de)两(liang)种金(jin)属组成(cheng)。两(liang)种不(bu)同(tong)(tong)(tong)材质(zhi)的(de)(de)(de)金(jin)属组成(cheng)闭合(he)回路,当(dang)两(liang)端存在温(wen)度(du)(du)梯度(du)(du)时,回路中(zhong)就会有电(dian)流(liu)通过(guo),此(ci)时两(liang)端之(zhi)间就存在电(dian)动势,通过(guo)连接(jie)电(dian)气仪表(二次(ci)仪表)可(ke)转换(huan)成(cheng)被测(ce)介(jie)质(zhi)的(de)(de)(de)温(wen)度(du)(du)数值。热(re)电(dian)偶(ou)(ou)(ou)的(de)(de)(de)有不(bu)同(tong)(tong)(tong)类型(xing)(xing)(xing) ,J型(xing)(xing)(xing)、K型(xing)(xing)(xing)、T型(xing)(xing)(xing)和(he)E型(xing)(xing)(xing)是最常见的(de)(de)(de)类型(xing)(xing)(xing),而R型(xing)(xing)(xing)、S型(xing)(xing)(xing)和(he)B型(xing)(xing)(xing)热(re)电(dian)偶(ou)(ou)(ou)则较多(duo)用(yong)于高(gao)温(wen)环境。根(gen)据使用(yong)场景的(de)(de)(de)不(bu)同(tong)(tong)(tong),可(ke)以定(ding)制(zhi)合(he)适(shi)的(de)(de)(de)检测(ce)结构。
