一、應(yīng)用
通常和顯示儀表、記錄儀表、電子計(jì)算機(jī)等配套使用。直接測(cè)量各種生產(chǎn)過(guò)程中0～1300℃范圍內(nèi)的液體、蒸汽和氣體介質(zhì)以及固體表面溫度。
二、特點(diǎn)
1、裝配簡(jiǎn)單，更換方便；
2、壓簧式感溫元件，抗振性能好；
3、測(cè)量范圍大；
4、機(jī)械強(qiáng)度高，耐壓性能好；
三、工作原理
熱電偶的電極由兩根不同導(dǎo)體材質(zhì)組成。當(dāng)測(cè)量端與參比端存在溫差時(shí)，就會(huì)產(chǎn)生熱電勢(shì)，工作儀表便顯示出熱電勢(shì)所對(duì)應(yīng)的溫度值?！?/p>
四、主要技術(shù)參數(shù)
1、產(chǎn)品執(zhí)行標(biāo)準(zhǔn)
IEC584
IEC1515
GB/T16839-1997
JB/T5582-91
2、常溫絕緣電阻
熱電偶在環(huán)境溫度為20±15℃，相對(duì)濕度不大于80%，試驗(yàn)電壓為500±50V（直流）電極與外套管之間的絕緣電阻≥100MΩ.m。

注：1、如無(wú)特殊約定，L僅為參考尺寸，熱電偶/熱電阻的插深應(yīng)按照熱安裝套管U尺寸計(jì)算；
2、元件為彈性鎧裝式元件，對(duì)于熱電阻元件Φ3只適用于單支元件。
