(3)、電容性干擾會(huì)導(dǎo)致jieshouqi電阻有關(guān)誤差，對(duì)于4-20mA兩線制環(huán)路，jieshouqi電阻通常為250Ω（取樣Uout=1～5V）這個(gè)電阻小到不足以產(chǎn)生明顯誤差，因此，可以允許的電線長(zhǎng)度比電壓遙測(cè)系統(tǒng)更長(zhǎng)更遠(yuǎn)； </p> <p>

溫度變送器是一種常見(jiàn)的儀器，溫度變送器的應(yīng)用范圍是十分廣的，在各個(gè)領(lǐng)域都有應(yīng)用溫度變送器，溫度變送器的工作原理是什么呢?熱電偶一般用于中高溫的測(cè)量，而熱電阻主要是低溫的測(cè)量。溫度變送器中選擇熱電偶和熱電阻的工作原理的區(qū)別是什么呢，下面為大家具體介紹一下吧。 </p> <p> 熱電偶熱電偶是工業(yè)上常用的溫度檢測(cè)元件之一，熱電偶工作原理是基于賽貝克(seeback)效應(yīng),即兩種不同成分的導(dǎo)體兩端連接成回路，如兩連接端溫度不同，則在回路內(nèi)產(chǎn)生熱電流的物理現(xiàn)象。其優(yōu)點(diǎn)是：①測(cè)量精度高。因熱電偶直接與被測(cè)對(duì)象接觸，不受中間介質(zhì)的影響。②測(cè)量范圍廣。常用的熱電偶從-50~+1600℃均可邊續(xù)測(cè)量，某些特殊熱電偶*低可測(cè)到-269℃(如金鐵鎳鉻)，zui高可達(dá)+2800℃(如鎢-錸)。③構(gòu)造簡(jiǎn)單，使用方便。熱電偶通常是由兩種不同的金屬絲組成，而且不受大小和開(kāi)頭的限制，外有保護(hù)套管，用起來(lái)非常方便。河北小型溫度變送器用途一體化溫度變送器能夠直接與溫度傳感器的DIN銜接頭相接，具有裝置花費(fèi)較低，體積小。</p><div

一體化溫度變送器和其他的變送器一樣，在使用的過(guò)程中需要很多要注意的地方，如果用戶不小心的使用幾個(gè)細(xì)節(jié)，會(huì)直接影響儀器的性能，破壞儀器的使用壽命，接下來(lái)為大家詳細(xì)的介紹用戶在使用一體化溫度變送器的注意事項(xiàng)： </p> <p> 1、一體化溫度變送器安裝的環(huán)境必須是在-20-+70℃內(nèi)，當(dāng)周?chē)h(huán)境溫度太高時(shí)，SBWZ/R信號(hào)轉(zhuǎn)換器和顯示模塊可以與熱電阻或熱電偶分離安裝。我公司配有分離安裝變送器的**防爆盒。2、用于危險(xiǎn)場(chǎng)所時(shí)，請(qǐng)注意防爆標(biāo)志與防護(hù)等級(jí)。 </p> <p> 3、加電前，請(qǐng)仔細(xì)檢查電源的正負(fù)極性，不能接錯(cuò)，否則可能造成不可知的后果。 </p> <p> 4、溫度變送器使用六個(gè)月后需進(jìn)行校驗(yàn)。 </p> <p> 5、SBW信號(hào)轉(zhuǎn)換器模塊用環(huán)氧樹(shù)脂灌封固化，以加強(qiáng)其防震性能，并防濕、防腐、防潮。 </p> <p> 一體化溫度變送器一般由測(cè)溫探頭(熱電偶或熱電阻傳感器)和兩線制固體電子單元組成。采用固體模塊形式將測(cè)溫探頭直接安裝在接線盒內(nèi)，從而形成一體化的變送器。一體化溫度變送器一般分為熱電阻和熱電偶型兩種類(lèi)型。目前一體化溫度變送器是現(xiàn)代工業(yè)現(xiàn)場(chǎng)、科研院所溫度測(cè)控的更新?lián)Q代產(chǎn)品，是集散系統(tǒng)、數(shù)字總線系統(tǒng)的必備產(chǎn)品。

熱電阻溫度變送器中采用的熱電阻是用半導(dǎo)體材料，大多為負(fù)溫度系數(shù)，即阻值隨溫度增加而降低。溫度變化會(huì)造成大的阻值改變，因此它是zui靈敏的溫度變送器。熱電阻體積非常小，對(duì)溫度變化的響應(yīng)也快。但熱敏電阻需要使用電流源，小尺寸也使它對(duì)自熱誤差極為敏感。熱電阻在兩條線上測(cè)量的是yiding 溫度，有較好的精度。熱電阻溫度變送器非常適合需要進(jìn)行快速和靈敏溫度測(cè)量的電流控制應(yīng)用。 </p> <p> 熱電偶溫度變送器: </p> <p> 熱電偶溫度變送器是溫度測(cè)量中zui常用的溫度變送器。其主要好處是寬溫度范圍和適應(yīng)各種大氣環(huán)境，而且結(jié)實(shí)、價(jià)低，無(wú)需供電，也是低價(jià)的。但熱電偶并不適合高精度的的測(cè)量和應(yīng)用。甘肅隔離溫度變送器廠家</p><p
