The advantages of pressure gauges, the main parts of pressure gauges and the working principle of pressure gauges?

General pressure gauges have the following advantages:

1. Simple structure, reliable and durable, easy to use and maintain.

2.Small appearance, light weight, wide range of measuring theory, obvious indication, direct reading.

3. It has sufficient accuracy and good stability.

4, the price is low.

What are the main components of a general pressure gauge?

General pressure gauges are mainly composed of the following parts: joints, spring tubes, sealing plates, movements, connecting rods, pointers, liners, watch cases, watch glass, and cover rings. The key components are joints, spring tubes and movements.

What is the working principle of a general pressure gauge?

The general working principle of a pressure gauge is: under the action of pressure and vacuum, the elastic deformation of the spring tube causes the displacement of the tube end. The displacement is amplified by the mechanical transmission mechanism (connecting rod and movement), transmitted to the indicating device, and then by the pressure. The hands are deflected on the dial to indicate the pressure or vacuum value.
