WRR-130鉑銠熱(re)電(dian)偶專業廠家的詳細介紹
鉑(bo)(bo)銠(lao)30-鉑(bo)(bo)銠(lao)6熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou)(B型(xing)熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou))為貴(gui)金(jin)屬(shu)熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou)。偶(ou)絲(si)直(zhi)徑規定為0.5mm,允許偏差-0.015mm,其正極(ji)(BP)的名義化學成分為鉑(bo)(bo)銠(lao)合金(jin),其中(zhong)含(han)(han)銠(lao)為30%,含(han)(han)鉑(bo)(bo)為70%,負極(ji)(BN)為鉑(bo)(bo)銠(lao)合金(jin),含(han)(han)銠(lao)為量6%,故俗(su)稱雙鉑(bo)(bo)銠(lao)熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou)。該熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou)長(chang)期(qi)zui高使(shi)(shi)用(yong)溫(wen)度(du)為1600℃,短期(qi)zui高使(shi)(shi)用(yong)溫(wen)度(du)為1800℃。B型(xing)熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou)在熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou)系列中(zhong)具有(you)準確度(du)zui高,穩定性,測(ce)溫(wen)溫(wen)區(qu)寬,使(shi)(shi)用(yong)壽(shou)命長(chang),測(ce)溫(wen)上限高等優(you)(you)點。適用(yong)于氧化性和(he)惰性氣氛(fen)中(zhong),也可短期(qi)用(yong)于真(zhen)空中(zhong),但不適用(yong)于還原性氣氛(fen)或(huo)(huo)含(han)(han)有(you)金(jin)屬(shu)或(huo)(huo)非金(jin)屬(shu)蒸氣氣氛(fen)中(zhong)。B型(xing)熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou)一個(ge)明顯的優(you)(you)點是(shi)不需用(yong)補(bu)償導線進行補(bu)償,因為在0~50℃范圍(wei)內(nei)熱(re)(re)(re)電(dian)(dian)(dian)(dian)勢小于3μV。B型(xing)熱(re)(re)(re)電(dian)(dian)(dian)(dian)偶(ou)不足之處是(shi)熱(re)(re)(re)電(dian)(dian)(dian)(dian)勢,熱(re)(re)(re)電(dian)(dian)(dian)(dian)勢率較小,靈(ling)敏度(du)低,高溫(wen)下(xia)機械強度(du)下(xia)降,對污染非常敏感,貴(gui)金(jin)屬(shu)材料昂貴(gui),因而(er)一次性投資較大(da)。
