磁翻柱液位計工作原理

磁(ci)翻(fan)柱(zhu)液(ye)(ye)位(wei)(wei)計測(ce)量液(ye)(ye)體時采用頂(ding)裝或(huo)旁通(tong)管側裝方式。磁(ci)翻(fan)柱(zhu)主體外加裝翻(fan)柱(zhu)液(ye)(ye)位(wei)(wei)指示器(qi)、液(ye)(ye)位(wei)(wei)開(kai)關(guan)及液(ye)(ye)位(wei)(wei)變(bian)送(song)器(qi)。磁(ci)單(dan)元置于浮球內部或(huo)通(tong)過頂(ding)桿(gan)與浮球相(xiang)連(lian)，當浮球連(lian)帶磁(ci)單(dan)元隨液(ye)(ye)位(wei)(wei)變(bian)化時，使磁(ci)性色塊（磁(ci)翻(fan)板）翻(fan)轉(zhuan)；磁(ci)性液(ye)(ye)位(wei)(wei)開(kai)關(guan)在對應(ying)液(ye)(ye)位(wei)(wei)點(dian)動作(zuo)；同時液(ye)(ye)位(wei)(wei)傳感(gan)器(qi)在浮球磁(ci)力的作(zuo)用下，輸出標準的變(bian)化電阻信(xin)(xin)號(hao)(hao)，再經過變(bian)送(song)器(qi)把電阻信(xin)(xin)號(hao)(hao)轉(zhuan)換成4~20mA電流(liu)信(xin)(xin)號(hao)(hao)輸出。

磁翻柱液位計護導管(guan)和(he)主(zhu)體(ti)(ti)管(guan)安(an)裝(zhuang)必須垂直，以保證浮球組件在主(zhu)體(ti)(ti)管(guan)內能(neng)上下(xia)運動自(zi)如(ru)。連桿不能(neng)彎曲必須垂直插入。安(an)裝(zhuang)完畢后(hou)，需(xu)對(dui)顯(xian)(xian)示(shi)器(qi)的翻柱用磁鋼引導一次使零位(wei)以上顯(xian)(xian)示(shi)為白色，零位(wei)以下(xia)顯(xian)(xian)示(shi)紅色。是在流(liu)體(ti)(ti)中(zhong)安(an)放一根非流(liu)線(xian)型游渦發生(sheng)體(ti)(ti),流(liu)體(ti)(ti)在發生(sheng)體(ti)(ti)兩(liang)側交(jiao)(jiao)替(ti)地分離釋放出兩(liang)串規則地交(jiao)(jiao)錯排列(lie)的游渦的儀表。

液位(wei)(wei)計安裝完(wan)畢后，需要用(yong)磁鋼進行校正(zheng)，對翻(fan)柱導引一次(ci)使(shi)零位(wei)(wei)以下顯示紅色，零位(wei)(wei)以上(shang)顯示白色。浮球(qiu)校正(zheng)主要是校正(zheng)傳感器的(de)零點和量(liang)程，將(jiang)浮球(qiu)置(zhi)于“零位(wei)(wei)”處(chu)(chu)，此(ci)時(shi)調整“零位(wei)(wei)”電(dian)位(wei)(wei)器，使(shi)輸出(chu)為4mA，再將(jiang)浮球(qiu)置(zhi)于滿“量(liang)程”處(chu)(chu)，調整“量(liang)程”電(dian)位(wei)(wei)器，使(shi)輸出(chu)為20mA，如此(ci)反復(fu)幾次(ci)，調試即可完(wan)畢。

按品種可分為(wei)微差變送(song)(song)器(qi)(qi)、差壓(ya)(ya)變送(song)(song)器(qi)(qi)、高靜(jing)壓(ya)(ya)變送(song)(song)器(qi)(qi)、絕對壓(ya)(ya)力(li)變送(song)(song)器(qi)(qi)、壓(ya)(ya)力(li)變送(song)(song)器(qi)(qi)、法蘭式(shi)液位(wei)變送(song)(song)器(qi)(qi)、遠傳(chuan)壓(ya)(ya)力(li)/差壓(ya)(ya)變送(song)(song)器(qi)(qi)，磁(ci)翻柱液位(wei)計(ji)。適用于石油、化(hua)工、冶金(jin)、造紙、紡織、醫藥、電力(li)等領域的(de)過程(cheng)控制和測量。
