Additional Considerations

In addition to the types mentioned above, pressure gauges can also be categorized as absolute, gauge, or differential depending on the reference pressure being measured. Absolute pressure gauges measure pressure relative to a perfect vacuum, gauge pressure gauges measure pressure relative to atmospheric pressure, and differential pressure gauges measure the difference in pressure between two points.

When selecting an air pressure gauge, there are several factors to consider. These include whether the gauge is fixed or portable, the type of pressure being measured (absolute, gauge, or differential), the specific type of pressure gauge (such as Bourdon tube, diaphragm, capsule, or bellows), and whether the gauge is dry or liquid-filled.

Other important criteria to consider are the pressure range, overpressure resistance, precision, dial diameter, and compatibility with the fluid being measured. By considering these factors, you can ensure that you select the right air pressure gauge for your specific application.
