结构分解图 Internal structure
说明: 防爆窗可释放因过载弹性元件破裂而产生的内部压力，增强了人员及设施的安全性。
Specification:explosion-proof window can release inner pressure caused by break of elastic component when over loaded, and thus security of personnel and establishment is ensured.
结构原理
仪表由导压系统（包括接头、弹簧管等）、齿轮传动机构、示数装置（指针与表盘）和外壳（包括表壳、表罩、表玻璃等）组成。
弹簧管在压力和真空的作用下，产生弹性变形引起管端位移，其位移通过机械传动机构进行放大，传递给示数装置，再由指针在刻有法定计量单位的度盘上指出被测压力或真空量值。
Configuration principle
The meter is composed of pressure leading system (including joint, spring tube, etc), gear wheel driving machine, indicator device (pointer and meter dial) and crust (including meter crust, meter cover, meter glass, etc).
Under the action of pressure and vacuum, spring tube will produce elastic deformation causing displacement at the end. The displacement is enlarged by mechanical driving device and transferred to indicator, and then the pointer of the meter dial, with measure unit on it, indicates the pressure value or vacuum value
