WRR-230鉑銠熱(re)電(dian)偶長期(qi)Z高使(shi)(shi)用(yong)溫度為1600℃,短期(qi)Z高使(shi)(shi)用(yong)溫度為1800℃。B型熱(re)電(dian)偶在熱(re)電(dian)偶系列中(zhong)具有準確(que)度Z高,穩定性(xing),測(ce)溫溫區寬,使(shi)(shi)用(yong)壽命(ming)長,測(ce)溫上限(xian)高等優點。
WRR-230鉑銠熱電偶上海廠家的詳細介紹
鉑(bo)(bo)銠(lao)(lao)30-鉑(bo)(bo)銠(lao)(lao)6熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou)(B型(xing)熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou))為(wei)(wei)貴(gui)金屬熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou)。偶(ou)絲直(zhi)徑規(gui)定為(wei)(wei)0.5mm,允許偏差-0.015mm,其正極(ji)(BP)的(de)名義(yi)化學成分為(wei)(wei)鉑(bo)(bo)銠(lao)(lao)合(he)金,其中含銠(lao)(lao)為(wei)(wei)30%,含鉑(bo)(bo)為(wei)(wei)70%,負極(ji)(BN)為(wei)(wei)鉑(bo)(bo)銠(lao)(lao)合(he)金,含銠(lao)(lao)為(wei)(wei)量6%,故(gu)俗稱雙(shuang)鉑(bo)(bo)銠(lao)(lao)熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou)。該熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou)長(chang)期(qi)zui高使用(yong)(yong)溫(wen)度為(wei)(wei)1600℃,短期(qi)zui高使用(yong)(yong)溫(wen)度為(wei)(wei)1800℃。B型(xing)熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou)在熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou)系列中具有準確(que)度zui高,穩定性(xing)(xing)(xing),測溫(wen)溫(wen)區寬,使用(yong)(yong)壽命長(chang),測溫(wen)上限高等優點。適用(yong)(yong)于氧化性(xing)(xing)(xing)和(he)惰性(xing)(xing)(xing)氣氛中,也可短期(qi)用(yong)(yong)于真空中,但不(bu)(bu)適用(yong)(yong)于還(huan)原性(xing)(xing)(xing)氣氛或含有金屬或非金屬蒸(zheng)氣氣氛中。B型(xing)熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou)一(yi)個明(ming)顯的(de)優點是不(bu)(bu)需(xu)用(yong)(yong)補償導線進行(xing)補償,因(yin)為(wei)(wei)在0~50℃范(fan)圍內熱(re)(re)電(dian)(dian)(dian)(dian)勢(shi)小于3μV。B型(xing)熱(re)(re)電(dian)(dian)(dian)(dian)偶(ou)不(bu)(bu)足之處是熱(re)(re)電(dian)(dian)(dian)(dian)勢(shi),熱(re)(re)電(dian)(dian)(dian)(dian)勢(shi)率較小,靈敏度低,高溫(wen)下機械強度下降,對污(wu)染非常(chang)敏感(gan),貴(gui)金屬材(cai)料昂貴(gui),因(yin)而(er)一(yi)次性(xing)(xing)(xing)投資較大。
