壓力校驗儀是基于“加在密閉液體上的壓強，能夠大小不變地由液體向各個方向傳遞。（帕斯卡定律）”進行工作的。壓力控制器通常由柱塞或螺桿活塞泵（手動的居多）產(chǎn)生壓力，并通過密閉管道分別傳導到被校表和標準表上進行刻度（指示值）對比（即校驗）。校驗的精度是由標準表的精度決定的，精密數(shù)字壓力計目前國內(nèi)*高精度為0.05級，液位控制儀在需要檢定被檢設備時很容易就能找到需要的高精度標準表。壓力校驗儀中有一種砝碼式活塞式壓力計，液位控制儀可以達到0.05級，是國家計量監(jiān)督部門標準計量設備。活塞式壓力計具有準確度高、性能穩(wěn)定、操作簡單等優(yōu)點，在量值傳遞、精密測量、常規(guī)測量方面得到了廣泛的推廣和使用。
活塞式壓力計誤差主要來源有兩個:一個是活塞有效面積A；另一個是砝碼質(zhì)量m。由于各地重力加速度不同，壓力控制器對活塞式壓力計的誤差影響很大。在不同地區(qū)使用活塞式壓力計要注意對砝碼的質(zhì)量按使用地點的重力加速度進行修正。根據(jù)以上的介紹，壓力控制器我們對活塞壓力計能夠有一定的了解。
