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(guò)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(lái)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。內(nèi)蒙古圓形電流變送器高美電流變送器怎么樣？?jī)r(jià)格大概多少？</p><div

電流變送器為了精確檢測(cè)輸入電流的變化，也為了能輸出與輸入電流成線性變化的直流信號(hào)，通常需要一個(gè)輔助電流變送器的工作電源。選用較多的是容易獲得的AC220V，也可以選擇直流電源，比如：DC24V等等。需要注意的是，有一些電流變送器，宣稱不需要輔助電源，即所謂的"無(wú)源型"電流變送器。對(duì)這種電流變送器，應(yīng)該慎重選用。所謂"無(wú)源型",并非是不需要電源，而是由電流變送器輸出信號(hào)后面的儀表提供工作電源，自然增加了變送器后面采集儀表的負(fù)擔(dān)。還有一種"無(wú)源型電流變送器",是利用電流互感器的二次電流做變送器的電源。這種變送器的缺點(diǎn)是，當(dāng)負(fù)載電流較小時(shí)，電流互感器的輸出電流自然較小，所提供給變送器的能量也減少，此時(shí)，電流變送器將產(chǎn)生非線性誤差，從而照成電流信號(hào)變送的誤差，所以，這種變送器也是需要慎重采用的。電流變送器與電流互感器有什么不同？山西漏電流變送器</p><p

這種輸入的交流電流，是國(guó)際統(tǒng)一的。原因在于，負(fù)載電流的范圍是很大的，從毫安到千安。特別是大電流負(fù)載，如果變送器能直接輸入，變送器的體積和端子規(guī)格都必須非常大。顯然，能通過(guò)幾千安培的端子，是非常大的。實(shí)際上，這些電流都通過(guò)電流互感器CT來(lái)變成小電流，常見(jiàn)的就是5A或1A。因此，國(guó)際上，規(guī)定變送器的輸入規(guī)格都是5A或1A。
