YB系列精密压力表
Diaphragm Seal Pressure Gauge
简 介
精密压力表主要用于检验普通压力表或精确测量对铜及铜合金不起腐蚀作用的液体，气体或蒸汽的压力和负压，广泛应用于工业生产过程精密测量和科学试验室等部门。
不锈钢精密压力表在普通精密压力表的基础上导压系统及外壳均采用了不锈钢材料。应用于耐腐蚀要求较高的工艺流程中对各种气体或蒸汽介质的压力和负压的测量。
本厂生产的YB-150型压力表在读数装置上设有
镜面，使仪表读数更加清晰准确。YB-150A型还设有调零装置（抗震锁定装置），确保用户使用方便。
耐震精密压力表内部充灌阻尼液和配套缓冲装置，具有良好的耐震性能。在被测介质的压力有强烈脉冲变化或压力冲击和在生产工艺中经常突然卸荷的场合，以及环境震动较大的场所中，耐震精密压力表都能进行精密测量。
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 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.

结构原理 Configuration Principle
导压系统（包括接头、弹簧管等）、齿轮传动机构、示数装置（指针与度盘）和外壳（包括表壳、表罩、表玻璃等）组成。仪表有较好的密封性并设有检封装置，能保护其内部测量机构免受机械损伤和污秽侵入。
仪表的作用原理是基于弹性元件（测量系统中的弹簧管）变形。在被测介质的压力作用下，近使弹簧管之末端产生相应弹性变形——位移，借助于拉杆经齿轮传动机构的传动并予放大，由固定于齿轮轴上的指针逐渐将被测值在度盘上指示出来。
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 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.
