電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)式液(ye)(ye)(ye)(ye)(ye)位計是采(cai)用測(ce)(ce)量(liang)(liang)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)(de)變化來測(ce)(ce)量(liang)(liang)液(ye)(ye)(ye)(ye)(ye)面的(de)(de)(de)高低的(de)(de)(de)。它是一(yi)根金(jin)(jin)屬(shu)棒插入盛(sheng)液(ye)(ye)(ye)(ye)(ye)容(rong)(rong)器(qi)內(nei)，金(jin)(jin)屬(shu)棒作(zuo)為電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)(de)一(yi)個極(ji)，容(rong)(rong)器(qi)壁作(zuo)為電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)(de)另一(yi)極(ji)。兩電(dian)(dian)(dian)(dian)(dian)極(ji)間的(de)(de)(de)介(jie)質即為液(ye)(ye)(ye)(ye)(ye)體及其上(shang)面的(de)(de)(de)氣體。由(you)于液(ye)(ye)(ye)(ye)(ye)體的(de)(de)(de)介(jie)電(dian)(dian)(dian)(dian)(dian)常數ε1和液(ye)(ye)(ye)(ye)(ye)面上(shang)的(de)(de)(de)介(jie)電(dian)(dian)(dian)(dian)(dian)常數ε2不同，比如：ε1>ε2，則(ze)當液(ye)(ye)(ye)(ye)(ye)位升高時，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)式液(ye)(ye)(ye)(ye)(ye)位計兩電(dian)(dian)(dian)(dian)(dian)極(ji)間總(zong)的(de)(de)(de)介(jie)電(dian)(dian)(dian)(dian)(dian)常數值(zhi)隨(sui)之(zhi)加大因而電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)量(liang)(liang)增大。反之(zhi)當液(ye)(ye)(ye)(ye)(ye)位下降，ε值(zhi)減小，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)量(liang)(liang)也減小。所以，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)式液(ye)(ye)(ye)(ye)(ye)位計可通過(guo)兩電(dian)(dian)(dian)(dian)(dian)極(ji)間的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)量(liang)(liang)的(de)(de)(de)變化來測(ce)(ce)量(liang)(liang)液(ye)(ye)(ye)(ye)(ye)位的(de)(de)(de)高低采(cai)購(gou)磁致伸縮位移傳(chuan)感(gan)器(qi)請找常州研拓智能科技(ji)有限(xian)公司，歡迎來電(dian)(dian)(dian)(dian)(dian)。無錫浮球(qiu)液(ye)(ye)(ye)(ye)(ye)位傳(chuan)感(gan)器(qi)定(ding)做
