眾所周知，導波雷達物位計的優點非常明顯，比如它測量精度高，易維護，可以滿足高溫、高壓、蒸汽、真(zhen)空(kong)、高粉塵等惡劣環境的(de)要求，在越(yue)來越(yue)多的(de)行業中廣泛被應(ying)用(yong)。但是再好的(de)東西(xi)，也會有一些問題(ti)，比(bi)如會出(chu)現(xian)故(gu)(gu)障，那(nei)么怎(zen)么去判斷故(gu)(gu)障是一個值得(de)被探討(tao)的(de)問題(ti)，只有發(fa)現(xian)問題(ti)，才(cai)能解決(jue)問題(ti)，從(cong)而達(da)到最有效果(guo)。下面給大家總結了幾種，最基本的(de)判斷導波雷達(da)物位計故(gu)(gu)障的(de)方法。

首先是(shi)(shi)(shi)目(mu)視檢(jian)查方(fang)法，就是(shi)(shi)(shi)不使用任何測(ce)(ce)試儀器(qi)，而是(shi)(shi)(shi)通(tong)(tong)過人的(de)感官觀察來發現故(gu)(gu)(gu)障。第二種(zhong)是(shi)(shi)(shi)斷(duan)路法，將我(wo)們(men)所認為(wei)的(de)可疑部位從(cong)整(zheng)機上(shang)斷(duan)開(kai)，看故(gu)(gu)(gu)障是(shi)(shi)(shi)否(fou)能(neng)消失，以確(que)定故(gu)(gu)(gu)障。第三(san)種(zhong)是(shi)(shi)(shi)更(geng)換(huan)方(fang)法，通(tong)(tong)過更(geng)換(huan)一(yi)些部件或電(dian)(dian)(dian)路板，確(que)定故(gu)(gu)(gu)障在某個位置(zhi)。第四(si)種(zhong)是(shi)(shi)(shi)阻(zu)法，電(dian)(dian)(dian)阻(zu)檢(jian)查法是(shi)(shi)(shi)在無(wu)電(dian)(dian)(dian)源的(de)情況下，用萬用表(biao)的(de)電(dian)(dian)(dian)阻(zu)塊檢(jian)查儀表(biao)的(de)整(zheng)條電(dian)(dian)(dian)路和(he)部分電(dian)(dian)(dian)路的(de)輸入、輸出電(dian)(dian)(dian)阻(zu)是(shi)(shi)(shi)否(fou)正(zheng)常，電(dian)(dian)(dian)容(rong)器(qi)是(shi)(shi)(shi)否(fou)損(sun)壞(huai)或泄漏(lou)，電(dian)(dian)(dian)感線(xian)圈和(he)變壓器(qi)是(shi)(shi)(shi)否(fou)斷(duan)開(kai)或短路。最后一(yi)種(zhong)是(shi)(shi)(shi)電(dian)(dian)(dian)流(liu)(liu)法，電(dian)(dian)(dian)流(liu)(liu)法分為(wei)直(zhi)接測(ce)(ce)量(liang)(liang)和(he)間接測(ce)(ce)量(liang)(liang)。直(zhi)接測(ce)(ce)量(liang)(liang)是(shi)(shi)(shi)將電(dian)(dian)(dian)路斷(duan)開(kai)后連接到電(dian)(dian)(dian)流(liu)(liu)表(biao)上(shang)，將測(ce)(ce)量(liang)(liang)的(de)電(dian)(dian)(dian)流(liu)(liu)值與儀表(biao)正(zheng)常狀態下的(de)值進行比較，以判斷(duan)故(gu)(gu)(gu)障。間接測(ce)(ce)量(liang)(liang)不用斷(duan)電(dian)(dian)(dian)，測(ce)(ce)量(liang)(liang)電(dian)(dian)(dian)阻(zu)上(shang)的(de)電(dian)(dian)(dian)壓降，并根據(ju)電(dian)(dian)(dian)阻(zu)值計算近(jin)似電(dian)(dian)(dian)流(liu)(liu)值。

以上這(zhe)幾種辦法都不復雜，屬于比較(jiao)簡(jian)單的操作，但是也(ye)需要技術維(wei)護人員具(ju)備一定(ding)的專業知識，并且耐(nai)心，細心才可以達到理想效果。
