點膠機水位傳感器 電容式油位傳感器
本電(dian)容(rong)油位(wei)(wei)傳感(gan)(gan)器(qi)(qi)測量原理是基于容(rong)器(qi)(qi)內(nei)電(dian)容(rong)的(de)(de)變(bian)(bian)化(hua)(hua)(hua),在這種情(qing)況下,傳感(gan)(gan)器(qi)(qi)的(de)(de)探(tan)桿與容(rong)器(qi)(qi) 壁形成正負兩(liang)極,容(rong)器(qi)(qi)內(nei)的(de)(de)液體(或固體)充當電(dian)介質。容(rong)器(qi)(qi)內(nei)液位(wei)(wei)的(de)(de)變(bian)(bian)化(hua)(hua)(hua)引(yin)起電(dian)容(rong)的(de)(de)變(bian)(bian)化(hua)(hua)(hua),一 個(ge)空的(de)(de)容(rong)器(qi)(qi)內(nei)電(dian)容(rong)較(jiao)低,而一個(ge)裝滿(man)液體的(de)(de)容(rong)器(qi)(qi)內(nei)電(dian)容(rong)就較(jiao)高。點(dian)膠機專用液位(wei)(wei)傳感(gan)(gan)器(qi)(qi) 電(dian)容(rong)式油位(wei)(wei)傳感(gan)(gan)器(qi)(qi)
