變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)(transmitter)是把傳(chuan)(chuan)感器(qi)(qi)(qi)(qi)的(de)輸(shu)出(chu)信(xin)(xin)號(hao)(hao)轉(zhuan)(zhuan)變(bian)為可(ke)被控制器(qi)(qi)(qi)(qi)識別的(de)信(xin)(xin)號(hao)(hao)(或(huo)將傳(chuan)(chuan)感器(qi)(qi)(qi)(qi)輸(shu)入的(de)非電(dian)(dian)量(liang)轉(zhuan)(zhuan)換(huan)成電(dian)(dian)信(xin)(xin)號(hao)(hao)同(tong)(tong)(tong)時放大以便供遠方測(ce)量(liang)和控制的(de)信(xin)(xin)號(hao)(hao)源)的(de)轉(zhuan)(zhuan)換(huan)器(qi)(qi)(qi)(qi)。傳(chuan)(chuan)感器(qi)(qi)(qi)(qi)和變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)一同(tong)(tong)(tong)構成自動控制的(de)監測(ce)信(xin)(xin)號(hao)(hao)源。不同(tong)(tong)(tong)的(de)物理量(liang)需(xu)要(yao)不同(tong)(tong)(tong)的(de)傳(chuan)(chuan)感器(qi)(qi)(qi)(qi)和相應的(de)變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)。變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)的(de)種類很多(duo)，用(yong)在工控儀表上面的(de)變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)主(zhu)要(yao)有溫(wen)度變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)、壓力變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)、流(liu)量(liang)變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)、電(dian)(dian)流(liu)變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)、電(dian)(dian)壓變(bian)送(song)(song)(song)器(qi)(qi)(qi)(qi)等等。
