Brief Introduction This pressure meter is principally used to test normal pressure meters or accurately measure the pressure and vacuum of such liquids, gases, or vapors that has no erosive attack on copper and copper alloy. It is widely used in fine measurement in industrial production process and adopted by scientific experiment laboratories or other sectors. For stainless steel precision pressure meter, based on normal precision pressure meter, the pressure connecting system and its outer housing is made of stainless steel, used to measure pressure or negative pressure of various gas or vapor mediums in technological processes with higher requirements of corrosion resistance. YB-150 model pressure meter produced by this factory is build with a mirror mounted on reading device, making value reading more accurate and clearer. For YB-150A te, a nulling device (shock resistance locking gear) is equipped so as to facilitate clients use. As shock resistance precision pressure meter is filled with damping liquid and supported with shock reducer, good capacity of shock resistance is obtained accordingly. In such occasions or places as measure pressures of tested mediums with violent changes of pulse or pressure attack, or in production technological process with sudden release of load, or environments with stronger vibration, the shock resisting precision pressure meter is capable to perform fine measurement. 主要技術(shù)指標(biāo) Main Technoiogy Data 規(guī)格 Specifcations 結(jié)構(gòu)原理 Configuration Principle 導(dǎo)壓系統(tǒng)（包括接頭、彈簧管等）、齒輪傳動(dòng)機(jī)構(gòu)、示數(shù)裝置（指針與度盤）和外殼（包括表殼、表罩、表玻璃等）組成。儀表有較好的密封性并設(shè)有檢封裝置，能保護(hù)其內(nèi)部測(cè)量機(jī)構(gòu)免受機(jī)械損傷和污穢侵入。 儀表的作用原理是基于彈性元件（測(cè)量系統(tǒng)中的彈簧管）變形。在被測(cè)介質(zhì)的壓力作用下，近使彈簧管之末端產(chǎn)生相應(yīng)彈性變形——位移，借助于拉桿經(jīng)齒輪傳動(dòng)機(jī)構(gòu)的傳動(dòng)并予放大，由固定于齒輪軸上的指針逐漸將被測(cè)值在度盤上指示出來(lái)。 Configuration principle This instrument comprises of indicating part of measuring system and outer housing. With its good leakproofness and sealing device based on examination, its interior measuring gear is prevented from mechanical damage and invasion of dirty objects. The action principle of this instrument is based on deformation of elastic cell (spring pipe in the measuring system). Under the pressure affect of tested medium, corresponding deformation displacement are generated by the end of spring pipe. Through the tranission and amplification by tension rod of the gear tranitting device, the value of such deformation is indicated on scale by the needle fixed on the axle of the gear. 外形尺寸 Overall Dimensions 單位 mm
