工(gong)作(zuo)原理

鎧(kai)(kai)裝(zhuang)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)的(de)(de)(de)工作原理是由(you)兩種不同成份的(de)(de)(de)導體(ti)兩端(duan)(duan)經焊接(jie)，形(xing)成回(hui)路，直接(jie)測(ce)溫(wen)(wen)端(duan)(duan)叫測(ce)量(liang)端(duan)(duan)，接(jie)線端(duan)(duan)叫參(can)比(bi)端(duan)(duan)。當測(ce)量(liang)端(duan)(duan)和(he)(he)參(can)比(bi)端(duan)(duan)存在溫(wen)(wen)差(cha)時，就會在回(hui)路中產(chan)生熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)流，接(jie)上顯(xian)示儀表(biao)，儀表(biao)上就會指示出熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)所產(chan)生的(de)(de)(de)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)動(dong)勢(shi)(shi)的(de)(de)(de)對(dui)應(ying)溫(wen)(wen)度值。鎧(kai)(kai)裝(zhuang)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)的(de)(de)(de)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)動(dong)勢(shi)(shi)將隨著測(ce)量(liang)端(duan)(duan)的(de)(de)(de)溫(wen)(wen)度升高而增長，熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)動(dong)勢(shi)(shi)的(de)(de)(de)大(da)小只(zhi)和(he)(he)鎧(kai)(kai)裝(zhuang)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)導體(ti)材質以(yi)及兩端(duan)(duan)溫(wen)(wen)差(cha)有關，和(he)(he)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)長度，直徑無(wu)關。鎧(kai)(kai)裝(zhuang)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)的(de)(de)(de)結構是由(you)導體(ti)，絕緣氧化鎂和(he)(he)1Cr18Ni9Ti不銹鋼(gang)保護管經多次拉(la)制而成，鎧(kai)(kai)裝(zhuang)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)產(chan)品主要由(you)接(jie)線盒，接(jie)線端(duan)(duan)子和(he)(he)鎧(kai)(kai)裝(zhuang)熱(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶(ou)(ou)組(zu)(zu)成基本結構，并配以(yi)各種安裝(zhuang)固定裝(zhuang)置組(zu)(zu)成。

主(zhu)要(yao)技(ji)術指標(biao)

測溫范圍和準(zhun)確(que)度(du)

注：1）t為被測溫(wen)度的******值。

鎧(kai)裝熱電偶熱響應時間

在溫度出現階躍變化時，熱電偶的輸出變化至相當于該階躍變化的50%，所需要的時間稱為熱響應時間，用T_0.5表示。

鎧裝熱(re)(re)電偶熱(re)(re)響(xiang)應時間(jian)不大于(yu)下表的規定：

絕緣(yuan)電阻

當周圍空氣(qi)溫度(du)為20±15℃，相對濕度(du)不大于(yu)80﹪時，絕緣型鎧(kai)裝(zhuang)熱電偶(ou)的(de)偶(ou)絲(si)與(yu)外套管之間的(de)絕緣電阻值(zhi)應符合(he)下(xia)表規(gui)定。
