差(cha)壓(ya)(ya)(ya)(ya)檢漏(lou)(lou)法(fa)差(cha)壓(ya)(ya)(ya)(ya)檢漏(lou)(lou)法(fa)的(de)(de)原理啟蒙(meng)于醫用(yong)天平，它是精確測量(liang)微(wei)量(liang)物(wu)品質(zhi)量(liang)的(de)(de)測量(liang)工具。使(shi)用(yong)者通過仔細調整天平一(yi)(yi)端的(de)(de)砝碼(ma)使(shi)兩(liang)端達到(dao)(dao)嚴格平衡(heng)(heng)，這樣(yang)(yang)被測物(wu)的(de)(de)質(zhi)量(liang)就(jiu)(jiu)可通過砝碼(ma)反映出來。差(cha)壓(ya)(ya)(ya)(ya)氣(qi)密檢漏(lou)(lou)儀的(de)(de)原理同天平一(yi)(yi)樣(yang)(yang)，首先我們將(jiang)相(xiang)同壓(ya)(ya)(ya)(ya)力(li)的(de)(de)氣(qi)體同時(shi)充入到(dao)(dao)被測物(wu)和基準物(wu)內，使(shi)差(cha)壓(ya)(ya)(ya)(ya)傳感(gan)(gan)器隔離(li)板兩(liang)邊的(de)(de)壓(ya)(ya)(ya)(ya)力(li)完全相(xiang)等，然(ran)后觀察其平衡(heng)(heng)情況。若被測物(wu)不漏(lou)(lou)，那么差(cha)壓(ya)(ya)(ya)(ya)傳感(gan)(gan)器隔離(li)板兩(liang)邊的(de)(de)壓(ya)(ya)(ya)(ya)力(li)將(jiang)保持平衡(heng)(heng)。如果被測物(wu)存在泄(xie)漏(lou)(lou)，那么它內部的(de)(de)壓(ya)(ya)(ya)(ya)力(li)會逐(zhu)漸降低，平衡(heng)(heng)就(jiu)(jiu)被破壞。這樣(yang)(yang)傳感(gan)(gan)器就(jiu)(jiu)可以(yi)檢測出隔離(li)板兩(liang)側(ce)因泄(xie)漏(lou)(lou)產生的(de)(de)差(cha)壓(ya)(ya)(ya)(ya)。而且，如果發生泄(xie)漏(lou)(lou)，泄(xie)漏(lou)(lou)率（ml/sec）的(de)(de)大小將(jiang)直接(jie)反映在兩(liang)側(ce)壓(ya)(ya)(ya)(ya)力(li)的(de)(de)失衡(heng)(heng)速(su)度上。漏(lou)(lou)孔是影響設(she)備(bei)密封(feng)性的(de)(de)常見問題之一(yi)(yi)。氣(qi)密性漏(lou)(lou)孔的(de)(de)價格
