Pressure is the ratio in the force area where the force is distributed, which is that the force per unit area is applied in each direction perpendicular to the surface of the object. The action of one force on another can be called pressure, which is the force applied to or distributed on the surface.

First, why do you want to measure pressure?

The measurement and control of fluid pressure is very important in process industry. Pressure sensors measure pressure, usually the pressure of gas or liquid. The pressure sensor acts as a sensor, which generates a signal according to the applied pressure, and the signal will be an electrical signal. Pressure sensors can be used to indirectly measure other variables, such as fluid/gas flow, speed, water level and height.

Second, what are the types of stress?

1. Air pressure

It is the pressure that an area is subjected to due to the force exerted by the atmosphere.

2. gauge pressure

Gauge pressure is the pressure relative to atmospheric pressure, which can be described as whether the pressure relative to atmospheric pressure is high or low.

3. Vacuum pressure

Vacuum pressure is a pressure below atmospheric pressure, which is measured by using a vacuum gauge, which will indicate the difference between atmospheric pressure and absolute pressure.

4. Absolute pressure

Measure absolute value higher than total vacuum or zero. Zero absolute value means no pressure at all.

5. Different pressures

It can be defined as the size difference between a certain pressure value and a certain reference pressure. Absolute pressure can be considered as differential pressure with reference to total vacuum or zero absolute pressure, and gauge pressure can be considered as differential pressure with reference to atmospheric pressure.

6. Static pressure and dynamic pressure

The static pressure is uniform in all directions, so the pressure measurement is independent of the immovable fluid flow direction. If pressure is exerted on the surface perpendicular to the flow direction, but has little effect on the surface parallel to the flow direction, this directional component existing in the moving fluid can be called dynamic pressure.
