點膠機水位傳感器 電容式油位傳感器
本電容(rong)(rong)(rong)油位(wei)傳感器(qi)(qi)(qi)測量原理是基(ji)于(yu)容(rong)(rong)(rong)器(qi)(qi)(qi)內(nei)(nei)電容(rong)(rong)(rong)的(de)(de)變化,在這(zhe)種情況下,傳感器(qi)(qi)(qi)的(de)(de)探(tan)桿與容(rong)(rong)(rong)器(qi)(qi)(qi) 壁形成正負(fu)兩極,容(rong)(rong)(rong)器(qi)(qi)(qi)內(nei)(nei)的(de)(de)液(ye)體(ti)(或(huo)固體(ti))充(chong)當電介(jie)質。容(rong)(rong)(rong)器(qi)(qi)(qi)內(nei)(nei)液(ye)位(wei)的(de)(de)變化引起電容(rong)(rong)(rong)的(de)(de)變化,一 個空的(de)(de)容(rong)(rong)(rong)器(qi)(qi)(qi)內(nei)(nei)電容(rong)(rong)(rong)較低,而一個裝滿液(ye)體(ti)的(de)(de)容(rong)(rong)(rong)器(qi)(qi)(qi)內(nei)(nei)電容(rong)(rong)(rong)就較高。點膠機專用液(ye)位(wei)傳感器(qi)(qi)(qi) 電容(rong)(rong)(rong)式油位(wei)傳感器(qi)(qi)(qi)
