IFM電容式傳感器KI5085性能參數
IFM電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)式(shi)傳(chuan)感器KI5085性能參(can)數
電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)式(shi)傳(chuan)感器的初始電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)量很(hen)小,而連接傳(chuan)感器和(he)電(dian)(dian)(dian)(dian)子線(xian)路的引(yin)線(xian)電(dian)(dian)(dian)(dian)纜電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)、電(dian)(dian)(dian)(dian)子線(xian)路的雜散(san)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)以及電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)極板與周圍導體構成的電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)等寄生(sheng)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)卻較大。寄生(sheng)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)的存在不(bu)但降(jiang)低了測量靈敏(min)度(du),而且引(yin)起非(fei)線(xian)性輸(shu)出。由于(yu)寄生(sheng)電(dian)(dian)(dian)(dian)容(rong)(rong)(rong)是隨機變化的.因而使傳(chuan)感器處于(yu)不(bu)穩定的工作狀態.影響測量準(zhun)確度(du)。
