1.鎧裝熱電阻的特點
鎧裝熱電阻是(shi)在(zai)裝(zhuang)(zhuang)配(pei)(pei)熱(re)(re)電阻(zu)(zu)(zu)的(de)(de)基礎(chu)上借鑒(jian)鎧裝(zhuang)(zhuang)熱(re)(re)電偶的(de)(de)制造(zao)(zao)技術發展(zhan)起來(lai)的(de)(de)熱(re)(re)電阻(zu)(zu)(zu)新品種，相(xiang)對于(yu)裝(zhuang)(zhuang)配(pei)(pei)熱(re)(re)電阻(zu)(zu)(zu)具有直徑小、能彎曲、熱(re)(re)響應時間快，安裝(zhuang)(zhuang)使用(yong)方便(bian)等(deng)特點(dian)。由(you)于(yu)熱(re)(re)電阻(zu)(zu)(zu)沒(mei)有耐高溫腐蝕的(de)(de)要求，用(yong)不銹(xiu)鋼作(zuo)保護(hu)管的(de)(de)鎧裝(zhuang)(zhuang)熱(re)(re)電阻(zu)(zu)(zu)可以代替原裝(zhuang)(zhuang)配(pei)(pei)熱(re)(re)電阻(zu)(zu)(zu)，適合批量生產(chan)，成本低，而且更耐震動、密封性好(hao)、使用(yong)壽命(ming)長(chang)。近年(nian)來(lai)越(yue)來(lai)越(yue)多的(de)(de)廠(chang)家采(cai)用(yong)鎧裝(zhuang)(zhuang)熱(re)(re)電阻(zu)(zu)(zu)作(zuo)為(wei)裝(zhuang)(zhuang)配(pei)(pei)熱(re)(re)電阻(zu)(zu)(zu)的(de)(de)芯子來(lai)改造(zao)(zao)傳(chuan)統的(de)(de)裝(zhuang)(zhuang)配(pei)(pei)熱(re)(re)電阻(zu)(zu)(zu)。隨著(zhu)技術的(de)(de)發展(zhan)和(he)人們使用(yong)觀念的(de)(de)進步，裝(zhuang)(zhuang)配(pei)(pei)熱(re)(re)電阻(zu)(zu)(zu)最(zui)終將被鎧裝(zhuang)(zhuang)熱(re)(re)電阻(zu)(zu)(zu)取代。
鎧裝熱電阻的(de)制(zhi)(zhi)造，首先(xian)是將熱(re)(re)(re)電阻引(yin)(yin)線(xian)(xian)(xian)（一般為純鎳絲）穿(chuan)入氧(yang)化鎂(mei)(mei)絕緣材(cai)(cai)料中，再一同(tong)穿(chuan)入不銹鋼保護管(guan)中，經過(guo)多次拉拔縮徑退火而(er)形成鎧裝(zhuang)熱(re)(re)(re)電阻引(yin)(yin)線(xian)(xian)(xian)（相當(dang)于(yu)(yu)鎧裝(zhuang)熱(re)(re)(re)電偶(ou)材(cai)(cai)料）；然后將熱(re)(re)(re)電阻感溫(wen)元件與(yu)已經下料成需要(yao)長度并剝(bo)出引(yin)(yin)線(xian)(xian)(xian)頭的(de)鎧裝(zhuang)熱(re)(re)(re)電阻引(yin)(yin)線(xian)(xian)(xian)對接(jie)(jie)焊接(jie)(jie)；最后與(yu)制(zhi)(zhi)作(zuo)(zuo)鎧裝(zhuang)熱(re)(re)(re)電偶(ou)的(de)方法類似完成測(ce)量端、接(jie)(jie)線(xian)(xian)(xian)端和(he)安(an)裝(zhuang)裝(zhuang)置(zhi)的(de)制(zhi)(zhi)作(zuo)(zuo)。由于(yu)(yu)鎧裝(zhuang)熱(re)(re)(re)電阻引(yin)(yin)線(xian)(xian)(xian)電阻率較大，所(suo)以沒(mei)有兩線(xian)(xian)(xian)制(zhi)(zhi)引(yin)(yin)線(xian)(xian)(xian)，一般為三(san)線(xian)(xian)(xian)制(zhi)(zhi)引(yin)(yin)線(xian)(xian)(xian)，四線(xian)(xian)(xian)制(zhi)(zhi)需要(yao)特別注明。鎧裝(zhuang)銅電阻由于(yu)(yu)測(ce)溫(wen)較低(di)，可(ke)用有機材(cai)(cai)料絕緣代替無機氧(yang)化鎂(mei)(mei)絕緣，制(zhi)(zhi)作(zuo)(zuo)工藝與(yu)鎧裝(zhuang)鉑電阻可(ke)以不同(tong)。

與熱(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)偶分類一樣(yang)，熱(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)按(an)照結構分為(wei)裝配熱(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、鎧裝熱(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)兩類；按(an)測(ce)溫元(yuan)件鉑電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、銅電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)，以及非(fei)標準化的鐵電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、鎳電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、銦電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、錳電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、碳(tan)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)等(deng)；按(an)分度號分為(wei)Pt100、Pt10、Cu50、Cu100，以及Pt1000、Pt800、Pt500等(deng)標稱(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)很大(da)分辨率很高的鉑電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)；根據用途分為(wei)標準鉑電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、耐(nai)腐蝕熱(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、耐(nai)磨熱(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、端面熱(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)、電(dian)(dian)(dian)(dian)(dian)(dian)機專(zhuan)用熱(re)(re)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)等(deng)等(deng)。
