無錫徽科特測控技(ji)術有(you)限公司HKT60P露點變送器是把壓力(li)信(xin)號傳到電子設備,進而在計算機(ji)顯示(shi)壓力(li)。

　　其原理大(da)(da)致是將水壓這種壓力的(de)力學信(xin)號(hao)轉變成電(dian)(dian)(dian)流(4-20mA)這樣的(de)電(dian)(dian)(dian)子信(xin)號(hao)壓力和電(dian)(dian)(dian)壓或電(dian)(dian)(dian)流大(da)(da)小(xiao)成線(xian)性關(guan)系,一(yi)般是正比(bi)關(guan)系,所以,變送器輸(shu)出的(de)電(dian)(dian)(dian)壓或電(dian)(dian)(dian)流隨壓力増(zeng)大(da)(da)而(er)變大(da)(da)。

　　由此得出一個壓(ya)力和(he)電(dian)(dian)(dian)(dian)壓(ya)或(huo)電(dian)(dian)(dian)(dian)流的(de)(de)(de)關系(xi)式,露點(dian)變送器(qi)的(de)(de)(de)被(bei)測(ce)介質的(de)(de)(de)兩(liang)(liang)種壓(ya)力通(tong)入(ru)高、低兩(liang)(liang)壓(ya)力室,低壓(ya)室壓(ya)力采(cai)用(yong)大氣壓(ya)或(huo)真空,作用(yong)在δ元(即敏感元件)的(de)(de)(de)兩(liang)(liang)側(ce)隔離膜(mo)(mo)片上,通(tong)過隔離片和(he)元件內的(de)(de)(de)填充(chong)液傳送到測(ce)量(liang)(liang)(liang)膜(mo)(mo)片兩(liang)(liang)側(ce)。露點(dian)變送器(qi)是由測(ce)量(liang)(liang)(liang)膜(mo)(mo)片與兩(liang)(liang)側(ce)絕綠片上的(de)(de)(de)電(dian)(dian)(dian)(dian)極各(ge)組(zu)成一個電(dian)(dian)(dian)(dian)容(rong)器(qi)。當兩(liang)(liang)側(ce)壓(ya)力不(bu)同時,致使測(ce)量(liang)(liang)(liang)膜(mo)(mo)片產(chan)生(sheng)位移,其位移量(liang)(liang)(liang)和(he)壓(ya)力差成正(zheng)比,故兩(liang)(liang)側(ce)電(dian)(dian)(dian)(dian)容(rong)量(liang)(liang)(liang)就不(bu)等,通(tong)過振蕩和(he)解(jie)調環節,轉換成與壓(ya)力成正(zheng)比的(de)(de)(de)信號。

　　露點變送器(qi)(qi)結合瑞士羅卓尼克(ke)溫濕度傳感器(qi)(qi)可將各(ge)種物(wu)位(wei)(wei)參數的(de)(de)變化(hua)轉換成標準電流信號(hao),遠傳至操作控(kong)制(zhi)室,供二次儀表(biao)或計(ji)算機進(jin)行集中(zhong)顯示、報(bao)警或自動(dong)控(kong)制(zhi)。其良好的(de)(de)結構及(ji)(ji)安(an)裝方式,可適用于高(gao)溫、高(gao)壓、強腐蝕、易結晶、防(fang)堵塞、防(fang)冷結以及(ji)(ji)固體粉狀(zhuang)、粒(li)狀(zhuang)物(wu)料等(deng)條件下的(de)(de)液(ye)位(wei)(wei),料位(wei)(wei)或物(wu)位(wei)(wei)的(de)(de)連續檢測(ce),可應用于各(ge)種工業(ye)過程中(zhong)的(de)(de)檢測(ce)控(kong)制(zhi)。
