TK-3051型壓力差壓變送器詳細介紹
一(yi)、工作原理 工作時,高、低壓(ya)(ya)側(ce)(ce)(ce)的隔離膜(mo)(mo)片(pian)(pian)和灌充(chong)(chong)液(ye)將(jiang)過程壓(ya)(ya)力傳(chuan)遞給灌充(chong)(chong)液(ye),接(jie)著灌充(chong)(chong)液(ye)將(jiang)壓(ya)(ya)力傳(chuan)遞到傳(chuan)感(gan)器(qi)(qi)中心(xin)的傳(chuan)感(gan)膜(mo)(mo)片(pian)(pian)上。傳(chuan)感(gan)膜(mo)(mo)片(pian)(pian)是一(yi)個張緊的彈性元(yuan)件,其位(wei)移隨所受壓(ya)(ya)而變(bian)化(對于GP表(biao)壓(ya)(ya)變(bian)送器(qi)(qi),大(da)氣壓(ya)(ya)如同施(shi)加在傳(chuan)感(gan)膜(mo)(mo)片(pian)(pian)的低壓(ya)(ya)側(ce)(ce)(ce)一(yi)樣)。AP絕(jue)壓(ya)(ya)變(bian)送器(qi)(qi),低壓(ya)(ya)側(ce)(ce)(ce)始終保持一(yi)個參(can)考壓(ya)(ya)力。傳(chuan)感(gan)膜(mo)(mo)片(pian)(pian)的zui大(da)位(wei)移量(liang)為(wei)0.004英寸(0.1毫米(mi)),且(qie)位(wei)移量(liang)與壓(ya)(ya)力成正比。兩側(ce)(ce)(ce)的電容極(ji)板(ban)檢測傳(chuan)感(gan)
傳感(gan)膜片和電(dian)容極板之(zhi)間電(dian)容的差值被轉(zhuan)換(huan)為(wei)相(xiang)應(ying)的電(dian)流,電(dian)壓或數字(zi)HART(高速可尋(xun)址遠(yuan)程發送器數據公(gong)路(lu))輸出信號(hao)。 |
