對(duì)熱電阻的安裝,應(yīng)注意有利于測溫安全可考及維修方便,而且不影響設(shè)備運(yùn)行和生產(chǎn)操作.要滿足以上要求,在選擇對(duì)熱電阻的安裝部位和插入深度時(shí)要注意以下幾點(diǎn): </p> <p> 1、為了使熱電阻的測量端與被測介質(zhì)之間有充分的熱交換,應(yīng)合理選擇測點(diǎn)位置,盡量避免在閥門,彎頭及管道和設(shè)備的死角附近裝設(shè)熱電阻. </p> <p> 2、帶有保護(hù)套管的熱電阻有傳熱和散熱損失,為了減少測量誤差,熱電偶和熱電阻應(yīng)該有足夠的插入深度: </p> <p> (1)對(duì)于測量管道中心流體溫度的熱電阻,一般都應(yīng)將其測量端插入到管道中心處(垂直安裝或傾斜安裝).如被測流體的管道直徑是200毫米,那熱電阻插入深度應(yīng)選擇100毫米; </p> <p> (2)對(duì)于高溫高壓和高速流體的溫度測量(如主蒸汽溫度),為了減小保護(hù)套對(duì)流體的阻力和防止保護(hù)套在流體作用下發(fā)生斷裂,可采取保護(hù)管淺插方式或采用熱套式熱電阻.淺插式的熱電阻保護(hù)套管,其插入主蒸汽管道的深度應(yīng)不小于75mm;熱套式熱電阻的標(biāo)準(zhǔn)插入深度為100mm; </p> <p> (3)假如需要測量是煙道內(nèi)煙氣的溫度,盡管煙道直徑為4m,熱電阻插入深度1 m即可. </p> <p> (4)當(dāng)測量原件插入深度超過1m時(shí),應(yīng)盡可能垂直安裝,或加裝支撐架和保護(hù)套管. </p><p> 插座式熱電阻 </p> <p> 應(yīng)用 </p> <p> 采用接插件形式，安裝方便。適用于測量-200-+450℃范圍內(nèi)液體、氣體及固體表面測溫。 </p> <p> 2、主要技術(shù)參數(shù) </p> <p> 精度等級(jí)：A、B </p> <p> 防護(hù)等級(jí)：IP65 </p> <p> 公稱壓力：常壓 </p> <p> 熱套式熱電阻 </p> <p> 1、應(yīng)用 </p> <p>

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，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。眉山熱電阻哪家專業(yè)</p><p
