YB系列精密壓力表簡   

      精密壓力表主要用于檢驗普通壓力表或精確測量對銅及銅合金不起腐蝕作用的液體，氣體或蒸汽的壓力和負壓，廣泛應用于工業生產過程精密測量和科學試驗室等部門。

      不銹鋼精密壓力表在普通精密壓力表的基礎上導壓系統及外殼均采用了不銹鋼材料。應用于耐腐蝕要求較高的工藝流程中對各種氣體或蒸汽介質的壓力和負壓的測量。

      本廠生產的YB-150型壓力表在讀數裝置上設有

鏡面，使儀表讀數更加清晰準確。YB-150A型還設有調零裝置（抗震鎖定裝置），確保用戶使用方便。

      耐震精密壓力表內部充灌阻尼液和配套緩沖裝置，具有良好的耐震性能。在被測介質的壓力有強烈脈沖變化或壓力沖擊和在生產工藝中經常突然卸荷的場合，以及環境震動較大的場所中，耐震精密壓力表都能進行精密測量。
 

      This pressure meter is principally used to test normal pressure meters or accuray 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 type, 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.

      導壓系統（包括接頭、彈簧管等）、齒輪傳動機構、示數裝置（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有檢封裝置，能保護其內部測量機構免受機械損傷和污穢侵入。

      儀表的作用原理是基于彈性元件（測量系統中的彈簧管）變形。在被測介質的壓力作用下，近使彈簧管之末端產生相應彈性變形——位移，借助于拉桿經齒輪傳動機構的傳動并予放大，由固定于齒輪軸上的指針逐漸將被測值在度盤上指示出來。

 

      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 transmission and amplification by tension rod of the gear transmitting device, the value of such deformation is indicated on scale by the needle fixed on the axle of the gear.
