七、外形尺寸

八、熱電阻數據連接

  熱(re)(re)電阻(zu)(zu)是(shi)把溫度變(bian)化轉換為電阻(zu)(zu)值變(bian)化的(de)一次元件，通常需要把電阻(zu)(zu)信號通過引(yin)線傳遞到計算機控制(zhi)裝置(zhi)或者其(qi)它一次儀表上。工業用熱(re)(re)電阻(zu)(zu)安裝在(zai)生產(chan)現場，與控制(zhi)室(shi)之間存在(zai)一定的(de)距離(li)，因此熱(re)(re)電阻(zu)(zu)的(de)引(yin)線對測量結果(guo)會有(you)較大的(de)影(ying)響(xiang)。

目前熱(re)電阻的引(yin)線主要(yao)有三種方式

昨天，全(quan)國民航(hang)正(zheng)式(shi)進入冬春新航(hang)季(ji)，該航(hang)季(ji)從2017年(nian)10月29日(ri)至2018年(nian)3月24日(ri)。隨(sui)著新航(hang)季(ji)的(de)開啟，國內多家航(hang)空公司也調整和航(hang)線布局。

在新航(hang)季，東航(hang)將新開(kai)(kai)63條國內航(hang)線(xian)(xian)，加密(mi)(mi)102條航(hang)線(xian)(xian)。其(qi)中，在航(hang)班(ban)(ban)上(shang)，東航(hang)新開(kai)(kai)浦東-西安(an)-布拉格航(hang)線(xian)(xian)，加密(mi)(mi)浦東-布里斯班(ban)(ban)等航(hang)線(xian)(xian)，明年春運期間，還將執飛上(shang)海-凱恩斯航(hang)線(xian)(xian)。在航(hang)班(ban)(ban)上(shang)，東航(hang)計(ji)劃新開(kai)(kai)航(hang)線(xian)(xian)57條，加密(mi)(mi)93條航(hang)線(xian)(xian)，主要分布在西北(bei)、華南等區(qu)域

○1二線制：在熱電(dian)阻的兩端各(ge)連(lian)接一根導線(xian)來引出電(dian)阻信(xin)號的方式(shi)叫二(er)線(xian)制(zhi)：這種引線(xian)方法很簡單，但由于連(lian)接導線(xian)必然存(cun)在引線(xian)電(dian)阻r，r大小與導線(xian)的材質和長度(du)(du)的因素有關，因此這種引線(xian)方式(shi)只適用于測量精度(du)(du)較低的場合(he)

○2三線制：在(zai)熱電阻的根(gen)部的一端連接(jie)一根(gen)引(yin)線，另一端連接(jie)兩(liang)根(gen)引(yin)線的方式(shi)(shi)稱為三線制，這種(zhong)方式(shi)(shi)通常與電橋配套使(shi)用，可以較(jiao)好的引(yin)線電阻的影(ying)響，是工(gong)業(ye)過程控制中的常用的。

○3四線制：在熱(re)(re)電(dian)(dian)阻(zu)的(de)根部(bu)兩(liang)(liang)端各連接兩(liang)(liang)根導線(xian)的(de)方式(shi)稱(cheng)為(wei)四(si)線(xian)制，其中兩(liang)(liang)根引線(xian)為(wei)熱(re)(re)電(dian)(dian)阻(zu)提供恒定(ding)電(dian)(dian)流(liu)I，把(ba)R轉換成電(dian)(dian)壓信號(hao)U，再通過(guo)另兩(liang)(liang)根引線(xian)把(ba)U引至二次儀表。可見這種引線(xian)方式(shi)可*引線(xian)的(de)電(dian)(dian)阻(zu)影響，主要用于高(gao)精度(du)的(de)溫度(du)檢(jian)測。

熱(re)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)采用三(san)(san)線(xian)(xian)(xian)(xian)制(zhi)接法。采用三(san)(san)線(xian)(xian)(xian)(xian)制(zhi)是(shi)(shi)為了連接導線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)引起的(de)(de)測(ce)量誤(wu)差(cha)。這(zhe)是(shi)(shi)因(yin)為測(ce)量熱(re)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)的(de)(de)電(dian)(dian)(dian)(dian)路一(yi)般(ban)是(shi)(shi)不(bu)平衡(heng)電(dian)(dian)(dian)(dian)橋(qiao)(qiao)。熱(re)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)作為電(dian)(dian)(dian)(dian)橋(qiao)(qiao)的(de)(de)一(yi)個(ge)橋(qiao)(qiao)臂電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)，其(qi)連接導線(xian)(xian)(xian)(xian)（從(cong)熱(re)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)到(dao)中控(kong)室(shi)）也成(cheng)為橋(qiao)(qiao)臂電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)的(de)(de)一(yi)部分(fen)，這(zhe)一(yi)部分(fen)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)是(shi)(shi)未(wei)知的(de)(de)且(qie)隨環(huan)境溫度變化，造成(cheng)測(ce)量誤(wu)差(cha)。采用三(san)(san)線(xian)(xian)(xian)(xian)制(zhi)，將導線(xian)(xian)(xian)(xian)一(yi)根接到(dao)電(dian)(dian)(dian)(dian)橋(qiao)(qiao)的(de)(de)電(dian)(dian)(dian)(dian)源端，其(qi)余(yu)兩根分(fen)別接到(dao)熱(re)電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)所在的(de)(de)橋(qiao)(qiao)臂及與其(qi)相鄰的(de)(de)橋(qiao)(qiao)臂上(shang)，這(zhe)樣******了導線(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)路電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)帶來的(de)(de)測(ce)量誤(wu)差(cha)。
