　　2.溫(wen)度控制和(he)送樣控制：控制(zhi)器的(de)(de)(de)溫(wen)(wen)度控制(zhi)旋鈕可以(yi)調節燃燒爐(lu)內硅碳管的(de)(de)(de)加熱(re)電(dian)流(liu)(liu)。當(dang)燃燒爐(lu)到達設定(ding)溫(wen)(wen)度1150℃,溫(wen)(wen)度控制(zhi)電(dian)路(lu)行(xing)為和自動調整加熱(re)電(dian)流(liu)(liu),確保爐(lu)中(zhong)的(de)(de)(de)高溫(wen)(wen)點工作在恒定(ding)的(de)(de)(de)溫(wen)(wen)度為1150℃(±3℃),以(yi)保證充分燃燒爐(lu)的(de)(de)(de)測量對象。采樣(yang)(yang)(yang)線就是控制(zhi)采樣(yang)(yang)(yang)電(dian)機的(de)(de)(de)正反(fan)轉，達到采樣(yang)(yang)(yang)定(ding)位的(de)(de)(de)目的(de)(de)(de)。路(lu)由(you)線路(lu)由(you)計算機控制(zhi)。

　　3.燃(ran)燒爐：定硫(liu)儀采(cai)用(yong)管(guan)(guan)狀高溫爐(lu)作為燃(ran)燒爐(lu)，加熱元(yuan)件為一端連接的雙螺紋(wen)硅(gui)(gui)碳(tan)管(guan)(guan)。燃(ran)燒管(guan)(guan)采(cai)用(yong)石英管(guan)(guan)，直接送入硅(gui)(gui)碳(tan)管(guan)(guan)，溫度(du)控(kong)制(zhi)電(dian)路向硅(gui)(gui)碳(tan)管(guan)(guan)加熱電(dian)流(liu)，由鉑銠熱電(dian)偶(ou)反饋溫度(du)信號。

　　4.空氣預處理及輸送部分：該部件(jian)由(you)電(dian)磁泵、空氣(qi)(qi)流量計(ji)、烘干(gan)機等組成。電(dian)磁泵驅動分(fen)別電(dian)解(jie)槽的(de)里(li)面的(de)空氣(qi)(qi),干(gan)燥器主(zhu)要(yao)是去除雜質等酸性氣(qi)(qi)體(ti)的(de)空氣(qi)(qi)和(he)水,因為電(dian)解(jie)池中的(de)空氣(qi)(qi)濕(shi)度大,所以需要(yao)經常烤和(he)更換硅膠(jiao),玻璃管(guan)流量計(ji)的(de)針閥旋鈕開關,調整(zheng)氣(qi)(qi)體(ti)流量。

　　5.信號處理與(yu)接口電路：電(dian)(dian)(dian)解池(chi)的指示(shi)(shi)電(dian)(dian)(dian)極發出的指示(shi)(shi)電(dian)(dian)(dian)位反(fan)映了電(dian)(dian)(dian)解池(chi)中(zhong)電(dian)(dian)(dian)解液的硫含量。將指示(shi)(shi)電(dian)(dian)(dian)極的信(xin)號(hao)(hao)放大處理后(hou)，控制電(dian)(dian)(dian)子門開關將電(dian)(dian)(dian)解電(dian)(dian)(dian)流輸出到(dao)電(dian)(dian)(dian)解槽中(zhong)的電(dian)(dian)(dian)解電(dian)(dian)(dian)極，將電(dian)(dian)(dian)解電(dian)(dian)(dian)流的庫(ku)侖積分(fen)送(song)到(dao)計算機(ji)進行(xing)處理。接口(kou)(kou)電(dian)(dian)(dian)路是專門為計算機(ji)輸入(ru)輸出端口(kou)(kou)的電(dian)(dian)(dian)壓轉換、隔離和采樣而(er)設計的。它主要(yao)用于(yu)防止信(xin)號(hao)(hao)之間的干擾(rao)。
