雙針雙管差壓表適用于對兩個相同或不同壓力， 進行測量并可對兩個測量壓力及二壓力
差值分別指示。產(chǎn)品分為YCS普通型和YCSH防腐型。YCS普通型適用于對無腐蝕性介質(zhì)
的測量。YCSH 防腐型可在具有腐蝕性介質(zhì)及環(huán)境中使用。
儀表由兩套各自獨立的測量系統(tǒng)和指示裝置組成。測量壓力通過測壓元件的彈性變形，
通過兩個測壓元件（彈簧管）之末端各自產(chǎn)生相應(yīng)的位移，借助于拉桿傳動機構(gòu)的傳動予以
放大， 由固定于齒輪軸上的紅、黑指針將所測值分別指示在度盤上，同時中間小盤顯示出二
壓力之差值。

Double Bourdon System Differential Pressure Gauges are designed to measure
difference between 2 pressures. 2 models available: YCS General available and YCSH
Corrosion-Proof. The YCS type is suitable to measuring the un-corrode medium and the
YCSH type could be used in corrode environments.The instrument has 2 independent measuring systems. The measured pressure deflects the elastic elements, displacements then take place to actuate gear mechanismsthrough linkages to carry 2 pointers traveling over instrument dial, and an auxiliary dialshows the pressure difference.
