IFM電容式傳感器KI5085性能參數
IFM電(dian)(dian)(dian)容(rong)(rong)式傳感器(qi)KI5085性能參數
電(dian)(dian)(dian)容(rong)(rong)式傳感器(qi)的初(chu)始電(dian)(dian)(dian)容(rong)(rong)量很小,而連接傳感器(qi)和電(dian)(dian)(dian)子線路(lu)的引線電(dian)(dian)(dian)纜電(dian)(dian)(dian)容(rong)(rong)、電(dian)(dian)(dian)子線路(lu)的雜散電(dian)(dian)(dian)容(rong)(rong)以及(ji)電(dian)(dian)(dian)容(rong)(rong)極板與(yu)周圍導(dao)體構成(cheng)的電(dian)(dian)(dian)容(rong)(rong)等寄(ji)生(sheng)(sheng)電(dian)(dian)(dian)容(rong)(rong)卻較大。寄(ji)生(sheng)(sheng)電(dian)(dian)(dian)容(rong)(rong)的存(cun)在不但降低了測量靈敏度,而且引起非線性輸出。由(you)于寄(ji)生(sheng)(sheng)電(dian)(dian)(dian)容(rong)(rong)是隨機變化的.因而使(shi)傳感器(qi)處于不穩定(ding)的工作(zuo)狀(zhuang)態.影響(xiang)測量準確度。
