精密压力表主要用来校验工业用普通压力表,也可用于精密测量对铜合金和合金结构等无腐蚀性、非结晶、非凝固的各种介质的压力。仪表由测量系统、指示部分和表壳等组成。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浸入; 仪表的作用原理是基于弹性元件形变。在被测介质的压力作用下,迫使弹簧之未端产生相应弹性形变-位移,借助于拉杆经齿轮转动机构的传动并予放人,由固定于齿轮轴上的指针逐将被测值在刻度盘上指示出来。 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 .
