<p> 電流變送器，英文名稱(chēng)為Current transducer，是變送器的一種，主要用于將主回路的直流或交流電流轉(zhuǎn)換為恒流環(huán)標(biāo)準(zhǔn)信號(hào)輸送出去，以用于下一環(huán)節(jié)的使用。其具有結(jié)構(gòu)簡(jiǎn)單、準(zhǔn)確度高、工作穩(wěn)定、抗干擾性強(qiáng)等諸多優(yōu)點(diǎn)，已**應(yīng)用于電動(dòng)機(jī)、發(fā)電機(jī)，內(nèi)蒙古電流變送器安裝，內(nèi)蒙古電流變送器安裝、空調(diào)，內(nèi)蒙古電流變送器安裝、配電柜等負(fù)載電流的自動(dòng)化監(jiān)控系統(tǒng)中。 </p> <p> 二、電流變送器原理--分類(lèi) </p> <p> 電流變送器根據(jù)電流形式的不同可分為直流電流變送器和交流電流變送器兩種(其中交流電流變送器根據(jù)其結(jié)構(gòu)形式的不同又可分為單路交流電流變送器和三路交流電路變送器);根據(jù)其輸出接線(xiàn)方式的不同可分為兩線(xiàn)制電流變送器和三線(xiàn)制電流變送器(其中三線(xiàn)制電流變送器的三個(gè)端口分別為電源正極、電源負(fù)極和信號(hào)的輸出);電流變送器還有許多其他的分類(lèi)方式，接下來(lái)我們就幾種主要的電流變送器做以詳細(xì)介紹。單相電流變送器的工作原理和工業(yè)應(yīng)用。內(nèi)蒙古電流變送器安裝</p><div

目前，國(guó)際上輸出信號(hào)的標(biāo)準(zhǔn)通常采用DC4-20mA，輸出直流信號(hào)也可以采用直流電壓（比如：DC0-10V等），要和電流變送器后面的儀表或自控裝置的輸入相符。 </p> 電流變送器的輸入過(guò)載能力 </p> <p> 負(fù)載電流過(guò)載或者系統(tǒng)發(fā)生故障時(shí)，對(duì)電流變送器而言，通常會(huì)承受非常大的過(guò)載電流。在此情形下，能否能承受大的過(guò)載電流，成為衡量電流變送器性能的重要指標(biāo)。例如：KH系列電流變送器，其在輸入電流過(guò)載2倍時(shí)，能長(zhǎng)期保證變送器不會(huì)損壞，而FP系列電流變送器，更能承受3倍的過(guò)載電流。海南電流變送器價(jià)格珠海電流變送器SINEAX

在我國(guó)工業(yè)發(fā)展升級(jí)的驅(qū)動(dòng)下，電力設(shè)備的安全性使用越來(lái)越受到重視。電流傳感器作為一個(gè)兼具保護(hù)性和監(jiān)控作用的工具，將會(huì)在未來(lái)的電網(wǎng)中起到更重要的意義。相比國(guó)外同類(lèi)產(chǎn)品，國(guó)內(nèi)的電流傳感器技術(shù)還有很大的差距需要彌補(bǔ)和提高。 </p> <p> 國(guó)內(nèi)也逐漸涌現(xiàn)出有很多新型產(chǎn)業(yè)，都需要傳感器的支持，無(wú)論是出于安全性考慮還是市場(chǎng)效益考慮，電流傳感器將會(huì)趨于更加高效可靠，在低碳環(huán)保的要求下，小型化也是未來(lái)的一大趨勢(shì)，這也將促進(jìn)國(guó)內(nèi)傳感器廠商投入更多的經(jīng)歷開(kāi)發(fā)新技術(shù)和產(chǎn)品。在不久的將來(lái)，電流傳感器將會(huì)在更多行業(yè)得到**應(yīng)用，同時(shí)將為新興物聯(lián)網(wǎng)打好基礎(chǔ)。

二線(xiàn)制4～20ma電路應(yīng)用,其工作電源和信號(hào)共用一根導(dǎo)線(xiàn),工作電源由接收端提供。為了避免50/60hz的工頻干擾,采用電流來(lái)傳輸信號(hào)。二線(xiàn)制方案需要考慮的主要問(wèn)題：確定所用***的數(shù)量,當(dāng)有多個(gè)***時(shí),它將要求電流變送器擁有一個(gè)較低的工作電源電壓。另外一種考慮是降低回路電流在接收端的壓降。電流變送器-電壓變送器-功率變送器-多功能電力儀表。</p><div
