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(jìn)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(dǎo)到被校表和標(biāo)準(zhǔn)表上進(jìn)行刻度（指示值）對比（即校驗）。校驗的精度是由標(biāo)準(zhǔn)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(shè)備時很容易就能找到需要的高精度標(biāo)準(zhǔn)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(dá)到0.05級，是國家計量監(jiān)督部門標(biāo)準(zhǔn)計量設(shè)備?；钊綁毫τ嬀哂袦?zhǔn)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(jìn)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。
