電流變送器概述電流變送器可以直接將被測(cè)主回路交流電流或者直流電流轉(zhuǎn)換成按線性比例輸出的DC4～20mA（通過250Ω電阻轉(zhuǎn)換DC1～5V或通過500Ω電阻轉(zhuǎn)換DC2～10V）恒流環(huán)標(biāo)準(zhǔn)信號(hào)，連續(xù)輸送到接收裝置（計(jì)算機(jī)或顯示儀表）。 </p> <p> 電流變送器分直流電流變送器和交流電流變送器兩種。交流電流變送器是一種能將被測(cè)交流電流轉(zhuǎn)換成按線性比例輸出直流電壓或直流電流的儀器，產(chǎn)品**應(yīng)用于電力、郵電、石油、煤炭、冶金、鐵道、市政等部門的電氣裝置、自動(dòng)控制以及調(diào)度系統(tǒng)。交流電流、電壓變送器具有單路、三路組合結(jié)構(gòu)形式，山西電流變送器安裝為什么要用電流變送器?電流變送器的原理是什么？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="海南電流變送器價(jià)格,電流變送器" src="https://tyunfile.71360.com/WaterMark/UploadFile/szmdjd/637363654683691407/8473764.png"></div><p> 交流電流變送器的選型方法： </p> <p> 是電力監(jiān)控系統(tǒng)的重要元件，其作用是將交流電流轉(zhuǎn)換成直流電壓或直流電流。同時(shí)，它還承擔(dān)強(qiáng)電系統(tǒng)和弱電系統(tǒng)（比如，計(jì)算機(jī)系統(tǒng)）的隔離作用，以保護(hù)計(jì)算機(jī)采集系統(tǒng)輸入不被高壓的交流電壓所擊穿。另外，通過電流變送器的轉(zhuǎn)換，與輸入的交流電流成比例的直流電流或直流電壓，更便于遠(yuǎn)距離傳輸，使遠(yuǎn)處的監(jiān)控裝置或監(jiān)控儀表，能方便的接收精確的電流信號(hào)。由于電流是反映電力系統(tǒng)負(fù)載大小的**重要的指標(biāo)，所以，電流變送器，是電力監(jiān) 控系統(tǒng)中，采用**多的自動(dòng)化儀表。如何選擇電流變送器，是能否準(zhǔn)確檢測(cè)和轉(zhuǎn)換交流電流的關(guān)鍵。如果不能合理的選擇合適的電流變送器，將造成今后監(jiān)控系統(tǒng)的誤差和失真。 </p><p> 三、電流變送器原理--兩線制電流變送器 </p> <p> 兩線制電流變送器，“兩線制”指的是其現(xiàn)場(chǎng)的電流變送器與其控制室的控制儀器之間*用兩根線來實(shí)現(xiàn)連接，這兩根線一根是電源線，一根是信號(hào)線(三線制電流變送器較兩線制多一根信號(hào)線，四線制電流變送器較三線制多一根電源線)。兩線制電流變送器線路少，不*可節(jié)省電纜線，還不易受到熱電偶、電阻壓降、溫漂等的影響;且其兩線的輸出口處易設(shè)防雷器件，可有效地防止雷爆等現(xiàn)象的發(fā)生。電壓-4至20mA電流變送器功能原理及電路圖。</p><div

但在信號(hào)需要遠(yuǎn)距離傳輸或使用環(huán)境中電網(wǎng)干擾較大的場(chǎng)合，電壓輸出型傳感器的使用受到了極大限制，暴露了抗干擾能力較差,線路損耗破壞了精度等等等缺點(diǎn)，而兩線制電流輸出型變送器以其具有極高的抗干擾能力得到了**應(yīng)用。 </p> <p> 電壓輸出型變送器抗干擾能力極差，線路損耗的破壞,談不上精度有多高,有時(shí)輸出的直流電壓上還疊加有交流成分，使單片機(jī)產(chǎn)生誤判斷，控制出現(xiàn)錯(cuò)誤，嚴(yán)重時(shí)還會(huì)損壞設(shè)備，輸出0－5V***不能遠(yuǎn)傳，遠(yuǎn)傳后線路壓降大，精確度大打折扣。很多的ADC,PLC,DCS的輸入信號(hào)端口都作成兩線制電流輸出型變送器4-20mA的,證明了電壓輸出型變送器被淘汰的必然趨勢(shì)。

數(shù)字變送器，“數(shù)字”指的是其輸出的信號(hào)是一種數(shù)字量，其采用光纖進(jìn)行傳送，可有效地避免傳送過程中的損耗及各類干擾;該類變送器還采用雙通道的形式來進(jìn)行測(cè)量，若兩路信號(hào)中一路是電流信號(hào)，一路是電壓信號(hào)的話，就可以實(shí)現(xiàn)對(duì)功率的測(cè)量，若其兩通道信號(hào)為相同屬性的話，就可以實(shí)現(xiàn)微差測(cè)量。 </p> <p> 變送器，“變”是指將輸入的某種信號(hào)轉(zhuǎn)換為可控信號(hào)，“送”是指將轉(zhuǎn)換完的可控信號(hào)輸送到下一模塊以便使用，變送器就是這樣一個(gè)對(duì)信號(hào)進(jìn)行轉(zhuǎn)換并傳送的裝置，顧名思義，電流變送器是變送器的一種，主要用于電流信號(hào)的轉(zhuǎn)換與輸送。海南電流變送器價(jià)格</p></p><br
