熱電偶的應用原理
耐磨切斷式(shi)熱(re)(re)電(dian)(dian)偶(ou)是工(gong)業上常(chang)(chang)用的(de)(de)溫度檢(jian)測元件之一。其優點(dian)是:①測量(liang)精度高。因熱(re)(re)電(dian)(dian)偶(ou)直接與被測對(dui)象接觸,不受(shou)中間(jian)介質的(de)(de)影響。②測量(liang)范(fan)圍(wei)廣。常(chang)(chang)用的(de)(de)熱(re)(re)電(dian)(dian)偶(ou)從-50~+1600℃均可(ke)(ke)邊續測量(liang),某些(xie)特殊(shu)熱(re)(re)電(dian)(dian)偶(ou)zui低可(ke)(ke)測到-269℃(如金鐵鎳鉻),高可(ke)(ke)達(da)+2800℃(如鎢-錸)。③構(gou)造(zao)簡(jian)單(dan),使用方便。熱(re)(re)電(dian)(dian)偶(ou)通常(chang)(chang)是由兩(liang)種不同的(de)(de)金屬絲(si)組成(cheng),而且不受(shou)大小(xiao)和開(kai)頭的(de)(de)限(xian)制,外(wai)有(you)保(bao)護套管,用起來非常(chang)(chang)方便。耐磨切斷式(shi)熱(re)(re)電(dian)(dian)偶(ou)將兩(liang)種不同材(cai)料的(de)(de)導(dao)(dao)體(ti)或(huo)半導(dao)(dao)體(ti)A和B焊(han)接起來,構(gou)成(cheng)一個(ge)(ge)閉合回路,當導(dao)(dao)體(ti)A和B的(de)(de)兩(liang)個(ge)(ge)執...
