What is the nominal diameter of the pressure gauge's casing, the measurement range of the pressure gauge, and the installation method of the pressure gauge?

What are the nominal diameters of the shells of general pressure gauges?

According to the provisions of China's pressure gauge standards, the diameter of the pressure gauge's casing is: 40, 60, 100, 150, 200mm.

Due to the requirements of the installation conditions, there are other pressure gauge outside diameters available, such as 33, 50, 75, 90mm and so on.

How many measurement ranges does a pressure gauge have?

According to China's pressure gauge standards, there are several types of pressure gauge ranges:

Pressure gauge: 0-0.1Mpa 0-0.16Mpa 0-0.25Mpa 0-0.4Mpa

          0－0.6Mpa 0－1Mpa 0－1.6Mpa 0－2.5Mpa

          0－4Mpa 0－6Mpa 0－10Mpa 0－16Mpa

          0-25Mpa 0-40Mpa 0-60Mpa 0-100Mpa

          0-160Mpa 0-250Mpa 0-400Mpa 0-600Mpa

 Vacuum gauge: －0.1－0Mpa

 Pressure vacuum gauge: －0.1－0.06Mpa －0.1－0.15Mpa －0.1－0.3Mpa

                －0.1－0.5Mpa －0.1－0.9Mpa

                －0.1-1.5Mpa －0.1－2.4Mpa

 There are several ways to install pressure gauges?

 The installation methods of general pressure gauges are divided into thread connection and panel connection.

The pressure gauge with screw connection is divided into three types: radial lower end; axial concentric or axial eccentric.

The panel-mounted connection pressure gauge is further divided into: radial lower back ring; axial concentric front ring; axial concentric rear ring and axial eccentric front ring.
