鎧裝鉑電阻作為一種溫度傳感器，它比裝配式鉑電阻直徑小，易彎曲，適宜安裝在管道狹窄和要求快速反應(yīng)、微型化等特殊場(chǎng)合。其可對(duì)-200~600℃溫度范圍內(nèi)的氣體、液體介質(zhì)和固體表面進(jìn)行自動(dòng)檢測(cè)，并且可直接用銅導(dǎo)線和二次儀表相連接使用，由于它具有良好的電輸出特性，可為顯示儀、記錄儀、調(diào)節(jié)器、掃描器、數(shù)據(jù)記錄儀以及電腦提供有效的輸入值。 </p> <p> 鎧裝電阻外保護(hù)管采用不銹鋼，內(nèi)充滿高密度氧化物質(zhì)絕緣體，因此它具有很強(qiáng)的抗污染和優(yōu)良的機(jī)械強(qiáng)度，適合安裝在環(huán)境惡劣的場(chǎng)合。 </p> <p> 鎧裝鉑電阻通常由鎧裝鉑熱電阻感溫元件、安裝固定裝置和接線裝置等主要部件組成。 </p><p>

</p> <p> （2）鎧裝熱電阻鎧裝熱電阻是由感溫元件（電阻體）、引線、絕緣材料、不銹鋼套管組合而成的堅(jiān)實(shí)體，它的外徑一般為φ1~φ8mm，小可達(dá)φmm。與普通型熱電阻相比，它有下列優(yōu)點(diǎn)： </p> <p> ①體積小，內(nèi)部無空氣隙，熱慣性上，測(cè)量滯后?。?</p> <p> ②機(jī)械性能好、耐振，抗沖擊； </p> <p> ③能彎曲，便于安裝 </p> <p> ④使用壽命長(zhǎng)。 </p> <p> （3）端面熱電阻端面熱電阻感溫元件由特殊處理的電阻絲材繞制，緊貼在溫度計(jì)端面。它與一般軸向熱電阻相比，能更正確和快速地反映被測(cè)端面的實(shí)際溫度，適用于測(cè)量軸瓦和其他機(jī)件的端面溫度。 </p> <p> （4）隔爆型熱電阻隔爆型熱電阻通過特殊結(jié)構(gòu)的接線盒，把其外殼內(nèi)部性混合氣體因受到火花或電弧等影電阻體的斷路修理必然要改變電阻絲的長(zhǎng)短而影響電阻值，為此更換新的電阻體為好，若采用焊接修理，焊后要校驗(yàn)合格后才能使用。 </p><div style="width:100%;text-align: center;"><img
