精密壓力表主要用來校驗工業(yè)用普通壓力表,也可用于精密測量對銅合金和合金結(jié)構(gòu)等無腐蝕性、非結(jié)晶、非凝固的各種介質(zhì)的壓力。儀表由測量系統(tǒng)、指示部分和表殼等組成。儀表有較好的密封性并設有檢封裝置,能保護其內(nèi)部測量機構(gòu)免受機械損傷和污穢浸入; 儀表的作用原理是基于彈性元件形變。在被測介質(zhì)的壓力作用下,迫使彈簧之未端產(chǎn)生相應彈性形變-位移,借助于拉桿經(jīng)齒輪轉(zhuǎn)動機構(gòu)的傳動并予放人,由固定于齒輪軸上的指針逐將被測值在刻度盤上指示出來。 Precision pressure meter is to use check the industrial normal pressure meter,and can be measure some medium pressure like have no corruption for copper, no crystal, no-concretion. The meter composed by test system,note parts and body. The meter has a better airproof feature,and have seaI check system, and can protect the detect depart be dirt or machine broken .
