溫度變送器正確的接地方法，用戶在應(yīng)用過程中總會(huì)出現(xiàn)諸多因素，正確的使用儀器可以在后期的使用的過程中減少許多不必要的麻煩。下面給大家詳細(xì)的介紹一下溫度變送器接地的**技巧。 </p> <p> 1，控制系統(tǒng)AC電源應(yīng)該來自于一個(gè)分開的系統(tǒng)，與其他設(shè)備和使用分開; </p> <p> 2，電源在設(shè)計(jì)時(shí)應(yīng)該考慮到初始電流的沖擊，至少能承受10個(gè)周期; </p> <p> 3，控制系統(tǒng)AC接地應(yīng)該建立在隔離變壓器或UPS上，或者在附近溫度變送器; </p> <p> 4，控制系統(tǒng)工作站AC電源應(yīng)該使用專門的插座; </p> <p> 5，當(dāng)連接現(xiàn)場設(shè)備電源幾個(gè)I/O接口轉(zhuǎn)接器時(shí)，應(yīng)該使用隔離柵條; </p> <p> 6，控制系統(tǒng)AC電源應(yīng)該由隔離變壓器或UPS供給; </p> <p> 7，當(dāng)AC和DC輸入連接到同樣的接線排，接線排必以適當(dāng)?shù)木鏄?biāo)簽標(biāo)出; </p> <p> 8，AC接地線應(yīng)該與載流線型號(hào)相當(dāng)或大一號(hào); </p> <p> 9，預(yù)留一根額外的線或使用一終端盒，以提供測(cè)試點(diǎn)。 </p> <p> 10，接地系統(tǒng)的電阻必須進(jìn)行測(cè)試，以保證接地能滿足控制系統(tǒng)制造商的要求。其實(shí)以上小技巧的也比較使用于平衡流量計(jì)。 </p> <p> 以上就是溫度變送器接地的**技巧，希望對(duì)大家能有所幫助。西安智能溫度變送器哪家好數(shù)顯溫度變送器采用硅橡膠或環(huán)氧樹脂密封結(jié)構(gòu)，因此耐震、耐濕、適合在惡劣的現(xiàn)場環(huán)境安裝使用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="西安智能溫度變送器哪家好,溫度變送器" src="https://tyunfile.71360.com/WaterMark/UploadFile/xalunqian/637329346476562500/8679498.png"></div><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、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。 </p><p> 隨著科技的快速發(fā)展，溫度變送器的種類越來繁多，應(yīng)用范圍都十分的廣，但是各種變送器的優(yōu)劣勢(shì)也是有區(qū)分的。接下來為大家詳細(xì)的介紹一下一體化溫度變送器的優(yōu)缺點(diǎn)。 </p> <p> 一體化溫度變送器有以下優(yōu)點(diǎn)：(1)節(jié)省了熱電偶系統(tǒng)補(bǔ)償導(dǎo)線或延長線的投資，只需兩根普通導(dǎo)線供電和輸出信號(hào)，這對(duì)于有眾多側(cè)濕點(diǎn)的過程控制有較大的經(jīng)濟(jì)效益；(2)**控制室與現(xiàn)場的連接導(dǎo)線中傳輸較強(qiáng)的4-20mA直流信號(hào)，比傳遞微弱的熱電勢(shì)的補(bǔ)償導(dǎo)線或連接線有更強(qiáng)的抗干擾能力;(3)體積小巧緊湊，只有幾十毫米的短柱體，用硅橡膠或樹脂固封在熱電倘或熱電阻套管接線端子盒內(nèi).適應(yīng)生產(chǎn)現(xiàn)場環(huán)境，防塵、抗蝕，不占額外空間。 </p> <p> 一體化溫度變送器的缺點(diǎn)是：每—款的變送器只適合配一種規(guī)格型號(hào)的敏感元件，也無法調(diào)整量程范圍.通用性差;一旦損壞，只能整體更換。 </p> <p> 一體化溫度變送器的基本誤差都小超過量程的±0.5%、環(huán)境溫度影響約為每1℃變動(dòng)不趙過0.05%.可安裝在-25一80℃的環(huán)境中。溫度變送器的失效形式分為風(fēng)險(xiǎn)失效、安全失效和無影響失效。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

近年來，我國工業(yè)現(xiàn)代化的進(jìn)程和電子信息產(chǎn)業(yè)連續(xù)的高速增長，帶動(dòng)了變送器市場的快速上升。溫度變送器用途十分廣闊，可用作溫度測(cè)量與控制、溫度補(bǔ)償、紫外光和紅外光測(cè)量、電腦彩色顯示器、切換式電源、熱水器、電冰箱、廚房設(shè)備、空調(diào)、汽車等領(lǐng)域。近年來汽車電子、消費(fèi)電子行業(yè)的快速增長帶動(dòng)了我國溫度變送器需求的快速增長。由于工農(nóng)業(yè)生產(chǎn)中溫度測(cè)量的范圍極寬，從零下幾百度到零上幾千度，而各種材料做成的溫度變送器只能在一定的溫度范圍內(nèi)使用。溫度變送器是通過物體隨溫度變化而改變某種特性來間接測(cè)量的。不少材料、元件的特性都隨溫度的變化而變化，所以能作溫度變送器的材料相當(dāng)多。溫度變送器隨溫度而引起物理參數(shù)變化的有：膨脹、電阻、電容、而電動(dòng)勢(shì)、磁性能、頻率、光學(xué)特性及熱噪聲等等。隨著生產(chǎn)的發(fā)展，新型溫度變送器還會(huì)不斷涌現(xiàn)。溫度變送器的用途也將越來越廣。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)。西安智能溫度變送器哪家好</p><p style="text-indent:25px">溫度變送器的自確診功用可以檢側(cè)變送器狀況，在變送器呈現(xiàn)失效時(shí)發(fā)出替告，把風(fēng)險(xiǎn)失效轉(zhuǎn)換為安全失效。西安智能溫度變送器哪家好</p><p> 我們應(yīng)該怎樣保護(hù)溫度變送器免受浪涌的危害呢？ </p> <p> 浪涌保護(hù)器，也叫防雷器，是一種為各種電子設(shè)備、儀器儀表、通訊線路提供安全防護(hù)的電子裝置。能夠有效的防止浪涌度溫度變送器的危害。當(dāng)電氣回路或者通信線路中因?yàn)橥饨绲母蓴_突然產(chǎn)生尖峰電流或者電壓時(shí)，浪涌保護(hù)器能在極短的時(shí)間內(nèi)導(dǎo)通分流，從而避免浪涌對(duì)回路中溫度變送器的損害。除了給溫度變送器添加浪涌保護(hù)器外，在現(xiàn)場也要做好各種接地、絕緣、屏蔽、保護(hù)電路等保護(hù)措施。這樣不僅能保護(hù)溫度變送器，在整個(gè)系統(tǒng)中的其他設(shè)備也能免受浪涌帶來的損壞，保證我們的儀器儀表正常運(yùn)行。西安智能溫度變送器哪家好</p></p><br
