压力测量仪表
pressure measuring instrument
- 一般在被测压力稳定的情况下，最大工作压力不应超过仪表上限值的2/3；测量脉动压力时，最大工作压力不应超过仪表上限的1/2；测量高压时，最大工作压力不应超过仪表上限的1/3。
Generally, under the situation of steady tested pressure, the maximum working pressure shall not exceed 2/3 of the upper limit value of the instrument; while in measuring pulse pressures, the maximum working pressure shall not exceed 1/2 of the upper limit value of the instrument; and while in measuring high pressures, the maximum working pressure shall not exceed 1/3 of the upper limit value of the instrument. - 为了扩大各种通用型压力仪表的使用范围，能适用于测量强腐蚀、高温、高粘度、易结晶、易凝固和有固体浮游物介质的压力，以及对某些测量介质不能直接进入通用型仪表内和便于清洗防止沉淀物质积聚的场合的压力检测时，必须采用由隔膜隔离器与通用型压力仪表组成一个系统的隔膜表。
To enlarge the using range of all kind of the universal pressure gauge,and make it suited for measuring the pressure of the service medium which is high corrosive and easily crystallized,or the medium which has floating solid.And inorder to prevent some service medium from entering the universal pressure gauge or to be wasy for clear the place where the precipitation is resistencde,there must have a diaphgram pressure gauge which is made up of a diaphragm and a universal pressure gauge. - 该仪表适用于测量氧气介质的压力。严禁接触油脂类物质。
This pressure gauge is used for measuring the pressure of oxygen medium.
