WRR2-220鉑銠熱電偶專業廠家的詳細介紹
鉑(bo)銠30-鉑(bo)銠6熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)(B型(xing)(xing)(xing)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou))為(wei)貴金(jin)屬(shu)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)。偶(ou)(ou)絲直徑規定(ding)為(wei)0.5mm,允許偏差-0.015mm,其正極(BP)的名義化學成分為(wei)鉑(bo)銠合(he)(he)金(jin),其中含銠為(wei)30%,含鉑(bo)為(wei)70%,負極(BN)為(wei)鉑(bo)銠合(he)(he)金(jin),含銠為(wei)量6%,故俗稱雙(shuang)鉑(bo)銠熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)。該熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)長(chang)期zui高(gao)使(shi)用(yong)(yong)(yong)溫度(du)(du)為(wei)1600℃,短(duan)期zui高(gao)使(shi)用(yong)(yong)(yong)溫度(du)(du)為(wei)1800℃。B型(xing)(xing)(xing)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)在熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)系列中具有準確(que)度(du)(du)zui高(gao),穩定(ding)性(xing),測溫溫區寬,使(shi)用(yong)(yong)(yong)壽命長(chang),測溫上限高(gao)等優點。適用(yong)(yong)(yong)于(yu)氧(yang)化性(xing)和惰性(xing)氣氛中,也可短(duan)期用(yong)(yong)(yong)于(yu)真空(kong)中,但不(bu)適用(yong)(yong)(yong)于(yu)還原性(xing)氣氛或(huo)含有金(jin)屬(shu)或(huo)非金(jin)屬(shu)蒸氣氣氛中。B型(xing)(xing)(xing)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)一個明顯的優點是不(bu)需用(yong)(yong)(yong)補償導(dao)線進行補償,因為(wei)在0~50℃范圍(wei)內(nei)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)小(xiao)于(yu)3μV。B型(xing)(xing)(xing)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)不(bu)足之處(chu)是熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)勢(shi),熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)勢(shi)率(lv)較(jiao)小(xiao),靈敏(min)度(du)(du)低(di),高(gao)溫下機械(xie)強度(du)(du)下降,對(dui)污染非常敏(min)感,貴金(jin)屬(shu)材料昂貴,WRR2-220鉑銠熱電偶(ou)主要技術參數:
