產(chǎn)品詳情
1、WRNK-130無固定裝置K型鎧裝熱電偶應(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)過程中的0°C~1300°C范圍內(nèi)液體,蒸汽和氣體介質(zhì)以及固體表面溫度。
2、WRNK-130無固定裝置K型鎧裝熱電偶特點(diǎn)
裝配簡(jiǎn)單,更換方便;
壓簧式感溫元件,抗震性能好;
測(cè)量范圍大;
機(jī)械強(qiáng)度高,耐壓性能好;
3、工作原理
鎧裝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。
