自(zi)1959年(nian)以(yi)來(lai)，pyrindus一直提供(gong)pyrindus 電阻、熱電偶、溫度探頭、電阻溫度計和傳感器等(deng)。Pyrindus能夠實現產(chan)品的(de)靈活性(xing)。我們的(de)產(chan)品pyrindus 電阻和熱(re)電偶溫度傳感器(qi)等(deng)用于化學(xue)、天然氣(qi)和煉油廠(chang)等(deng)方(fang)面中。

主要產品：

pyrindus電阻和(he)熱電偶(ou)

一、pyrindus電阻

PYRINDUS常溫(wen)絕(jue)緣電阻：

     常溫(wen)絕緣電(dian)阻的試(shi)驗電(dian)壓為直流500±50V，測量常溫(wen)絕緣電阻的大氣條件(jian)為：溫(wen)度(du)15～35℃，相(xiang)對濕度(du)45*，大氣壓力86～106KPa。熱(re)電偶(ou)在(zai)該(gai)條件下放置(zhi)時間不小于2小時。

對于長度超過1米的(de)熱電偶(ou)，它的(de)常溫絕(jue)緣電阻值(zhi)與其長度(du)的(de)乘積應不(bu)小(xiao)于(yu)100MW·m。

對于長度(du)等(deng)于或不足(zu)1m的(de)熱電(dian)(dian)偶，它的(de)常(chang)溫絕緣電(dian)(dian)阻值應(ying)不小于(yu)100MW。

二(er)、熱電偶

熱電偶是(shi)溫度(du)測量儀表(biao)中常用的(de)測溫元(yuan)件(jian)，是(shi)由兩(liang)(liang)種不(bu)同成分的(de)導體兩(liang)(liang)端接合成回(hui)路時，當兩(liang)(liang)接合點(dian) 熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶溫(wen)度(du)(du)不(bu)同時，就(jiu)會在(zai)回路內產生熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)流。如果熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶的(de)工作(zuo)端(duan)(duan)與(yu)(yu)參比端(duan)(duan)存有(you)溫(wen)差時，顯示儀表將會指示出(chu)熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶產生的(de)熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)勢所對(dui)應的(de)溫(wen)度(du)(du)值。熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶的(de)熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)動熱(re)(re)(re)(re)將隨著(zhu)測(ce)量端(duan)(duan)溫(wen)度(du)(du)升(sheng)高而增長(chang)，它的(de)大小只與(yu)(yu)熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶材料和兩(liang)端(duan)(duan)的(de)溫(wen)度(du)(du)有(you)關，與(yu)(yu)熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)*的(de)長(chang)度(du)(du)、直(zhi)徑無關。各種熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)偶的(de)外形(xing)常因需要而*不(bu)相(xiang)同，但是它們的(de)基本結構卻大致相(xiang)同，通常由熱(re)(re)(re)(re)電(dian)(dian)(dian)(dian)(dian)*、絕緣套(tao)(tao)保(bao)護管和接線盒等(deng)主要部分組成，通常和顯示儀表，記錄(lu)儀表和電(dian)(dian)(dian)(dian)(dian)子調節器配(pei)套(tao)(tao)使(shi)用。
