雙針雙管差壓表適用于對(duì)兩個(gè)相同或不同壓力, 進(jìn)行測(cè)量并可對(duì)兩個(gè)測(cè)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(duì)無(wú)腐蝕性介質(zhì)
的測(cè)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(dú)立的測(cè)量系統(tǒng)和指示裝置組成。測(cè)量壓力通過測(cè)壓元件的彈性變形,
通過兩個(gè)測(cè)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(dòng)機(jī)構(gòu)的傳動(dòng)予以
放大, 由固定于齒輪軸上的紅、黑指針將所測(cè)值分別指示在度盤上,同時(shí)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.
