產品解說E+H變送器,E+H作用

模塊化溫(wen)度變送器在流程(cheng)工業領域內進行(xing)度溫(wen)度測量，應用廣泛，支持(chi)HART®通(tong)信。

儀表輸(shu)出有用(yong)的附加診斷(duan)信(xin)息(xi)，測量(liang)性能穩(wen)定(ding)，有助(zhu)于(yu)提(ti)高(gao)過程效率，確保工(gong)廠(chang)平穩(wen)運行(xing)。

溫(wen)度(du)變送(song)器支持HART®通信，可以將不(bu)同類型的(de)輸(shu)入信號比例轉換成4...20 mA模擬量輸(shu)出信號

變(bian)(bian)送(song)器(qi)(qi)(qi)是把(ba)傳感(gan)器(qi)(qi)(qi)的(de)(de)(de)輸出信(xin)(xin)號(hao)(hao)轉變(bian)(bian)為(wei)(wei)可被控制(zhi)器(qi)(qi)(qi)識別(bie)的(de)(de)(de)信(xin)(xin)號(hao)(hao)的(de)(de)(de)轉換器(qi)(qi)(qi)。至于有時(shi)候與(yu)傳感(gan)器(qi)(qi)(qi)通用是因(yin)為(wei)(wei)現(xian)代(dai)的(de)(de)(de)多(duo)數傳感(gan)器(qi)(qi)(qi)的(de)(de)(de)輸出信(xin)(xin)號(hao)(hao)已經是通用的(de)(de)(de)控制(zhi)器(qi)(qi)(qi)可以接收的(de)(de)(de)信(xin)(xin)號(hao)(hao)，此信(xin)(xin)號(hao)(hao)可以不經過變(bian)(bian)送(song)器(qi)(qi)(qi)的(de)(de)(de)轉換直接為(wei)(wei)控制(zhi)器(qi)(qi)(qi)所識別(bie)。所以，傳統意義(yi)上的(de)(de)(de)“變(bian)(bian)送(song)器(qi)(qi)(qi)"意義(yi)應該(gai)是：“把(ba)傳感(gan)器(qi)(qi)(qi)的(de)(de)(de)輸出信(xin)(xin)號(hao)(hao)轉換為(wei)(wei)可以被控制(zhi)器(qi)(qi)(qi)或者測量(liang)儀(yi)表(biao)所接受標(biao)準信(xin)(xin)號(hao)(hao)的(de)(de)(de)儀(yi)器(qi)(qi)(qi)

通(tong)用輸入包括熱(re)(re)電(dian)阻（RTD）、熱(re)(re)電(dian)偶（TC）, 電(dian)阻（Ω）和(he)電(dian)壓（mV）信號(hao)

高(gao)(gao)可靠性、高(gao)(gao)長期穩定性、高(gao)(gao)測(ce)量(liang)精度(du)，配備高(gao)(gao)級診斷功能，保證安全測(ce)量(liang)

是把傳感(gan)器(qi)(qi)(qi)(qi)的(de)(de)(de)輸出信(xin)號(hao)轉(zhuan)變(bian)為(wei)可(ke)被控制(zhi)器(qi)(qi)(qi)(qi)識別的(de)(de)(de)信(xin)號(hao)(或將(jiang)傳感(gan)器(qi)(qi)(qi)(qi)輸入的(de)(de)(de)非電量(liang)(liang)轉(zhuan)換成電信(xin)號(hao)同(tong)時放大(da)以便供(gong)遠方測量(liang)(liang)和控制(zhi)的(de)(de)(de)信(xin)號(hao)源)的(de)(de)(de)轉(zhuan)換器(qi)(qi)(qi)(qi)。傳感(gan)器(qi)(qi)(qi)(qi)和變(bian)送(song)(song)器(qi)(qi)(qi)(qi)一同(tong)構成自動控制(zhi)的(de)(de)(de)監測信(xin)號(hao)源。不同(tong)的(de)(de)(de)物理量(liang)(liang)需要不同(tong)的(de)(de)(de)傳感(gan)器(qi)(qi)(qi)(qi)和相應(ying)的(de)(de)(de)變(bian)送(song)(song)器(qi)(qi)(qi)(qi)。變(bian)送(song)(song)器(qi)(qi)(qi)(qi)的(de)(de)(de)種類很多，用在工控儀表上面的(de)(de)(de)變(bian)送(song)(song)器(qi)(qi)(qi)(qi)主要有溫度(du)變(bian)送(song)(song)器(qi)(qi)(qi)(qi)、壓力變(bian)送(song)(song)器(qi)(qi)(qi)(qi)、流量(liang)(liang)變(bian)送(song)(song)器(qi)(qi)(qi)(qi)、電流變(bian)送(song)(song)器(qi)(qi)(qi)(qi)、電壓變(bian)送(song)(song)器(qi)(qi)(qi)(qi)等等。

持續傳感器和設(she)備(bei)監測，工作(zuo)可靠

診斷(duan)信息符合NAMUR NE 107標準(zhun)

免費軟件(jian)幫助用戶輕松配置儀表

加壓(ya)變(bian)送(song)器(qi)輸(shu)出不(bu)變(bian)化，再加壓(ya)變(bian)送(song)器(qi)輸(shu)出突然變(bian)化，泄壓(ya)變(bian)送(song)器(qi)零位回不(bu)去(qu)。 產生此(ci)現(xian)象的原(yuan)因極有可能是壓(ya)力傳(chuan)感器(qi)密封圈(quan)引起的。

是否符合(he)供(gong)電(dian)要求；電(dian)源與(yu)變送器及負(fu)載設備之間有(you)無接線(xian)錯誤(wu)。如果變送器接線(xian)端子(zi)上無電(dian)壓或極性接反均可造成變送器無電(dian)壓信號輸出。

壓力傳(chuan)感器(qi)及(ji)變送(song)器(qi)的外殼(ke)一般需接(jie)地，信號(hao)電(dian)(dian)纜線不得與(yu)動力電(dian)(dian)纜混合鋪設(she)，傳(chuan)感器(qi)及(ji)變送(song)器(qi)周圍(wei)應避免有強電(dian)(dian)磁干擾(rao)。傳(chuan)感器(qi)及(ji)變送(song)器(qi)在(zai)使用 變送(song)器(qi)（圖8）中應按行業規定(ding)進行周期檢定(ding)。
