溫度傳感器元件的正常工作是要滿足其工作條件的，其中之一就是它的工作電流，由于溫度傳感器具有電阻值，當(dāng)電流流過溫度傳感器元件時(shí)，會(huì)有功率損耗，就會(huì)發(fā)熱，所以為了減小傳感器本身的發(fā)熱引起測(cè)溫誤差，所以要在滿足傳感器正常工作的條件下，盡量減少其本身的發(fā)熱。這就是為什么溫度傳感器要在恒定小電流條件下使用的原因。所以比如鉑熱電阻的常規(guī)工作電流是5MA，但我們推薦的工作電流是1MA。原因就是要減少溫度傳感器元件的自熱引起測(cè)量誤差。電流恒定，其輸出才會(huì)有溫度和電勢(shì)的線性關(guān)系，陜西顯示型溫度變送器價(jià)格，陜西顯示型溫度變送器價(jià)格。 </p> <p> 溫度傳感器的插入深度也是容易忽視的一個(gè)問題，有些客戶要求插入深度很短但是直徑比較大，這是不合理的，尤其是在高溫的情況下這是不可取的，理論上說溫度傳感器的插入深度一般可按實(shí)際需要決定。但*少插入深度不應(yīng)少于溫度傳感器保護(hù)套管直徑的8-10倍。這樣才能保證溫度傳感器性能穩(wěn)定。了解了溫度傳感器的工作電流和插入深度對(duì)我們選定和使用溫度傳感器是很有必要的，陜西顯示型溫度變送器價(jià)格。如果忽視這兩個(gè)細(xì)節(jié)問題很容易造成溫度傳感器性能不穩(wěn)定甚至損壞。溫度變送器將物理測(cè)量信號(hào)或普通電信號(hào)轉(zhuǎn)換為標(biāo)準(zhǔn)電信號(hào)輸出或能夠以通訊協(xié)議方式輸出的設(shè)備。陜西顯示型溫度變送器價(jià)格</p><div

</p><p> 一體化溫度變送器和其他的變送器一樣，在使用的過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)周圍環(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。溫度變送器模塊的優(yōu)點(diǎn)有：低功耗，導(dǎo)軌安裝，可以密集安裝；更加智能化、數(shù)字化調(diào)校，主動(dòng)零點(diǎn)校準(zhǔn)。</p><div
