The concept of pressure for aspects of Life
In everyday life..
Pressure is one of the most important learning materials to be learned even in many aspects of our lives requiring the application of the concept of pressure itself.

Pressure is a very common characteristic, especially when we speak in the context of physics and instrumentation systems.
similarly in everyday life of course we very often see or experience or even provide a pressure. the pressure is very much of its kind and the discussion of the pressure itself is very broad.
Knowledge of this pressure is very important and also very broad and even penetrating various aspects of life of course we not only need to just know the concept of the voltage itself but how the measurement is also very important.
➩ "According to physicists"
Pressure is a force that an object does to another object and the pressure is dependent on the surface of the object that puts pressure on another object.
In general, Pressure can be regarded as a kind of pressure, pressure can be generated by liquids, gases or solids.
Pressure can be measured as absolute pressure, pressure measured or differential pressure :
➩ Absolute pressure is the total pressure generated by the medium
➩ Whereas differential Pressure is the difference between the two pressures.
➩ The measured pressure is a special type of differential pressure expressed as follows :
Where :
➩ Measurable pressure
➩ Absolute pressure, and
➩ Atmospheric pressure
A vacuum on the other hand is defined as a gas chamber whose pressure is less than atmospheric pressure. This empty indoor pressure is a kind of differential pressure :
From showing that, the higher the tube space affects the position and the value of the maximum pressure on the back of the cylinder. The value and position of the separation point more in the backward direction is in line with the increase in free flow. The pressure drop occurs on the back of the high free flow
The basic unit of pressure in the Cgs is
The SI standard unit for pressure is Newton per square meter ( ) or pascal (Pa).
Factors that determine the overall frequency response of the pressure measurement system should be determined by calibration. Estimates of these temperaments can be obtained by the following analysis.
Above picture, Fluctuating pressure has frequency and amplitude of Po and works on tubes of length L and radius r.
Low Pressure Measurements
Measurement of low pressure
The measurement of low pressure is a field of specialization itself that requires the coexistence of the experimental implementers. for medium vacuum pressure measurements, we can use bourdon measurements, manometers and diaphragm gauges.
Low pressure measurements are usually not possible with conventional gauges. In this connection, we will only question the measurement at absolute pressure. at the end of this tube there is a space with volume V corresponding to the pressure sensitive transducer.
Pressure coefficient factors
The factors that influence from the pressure coefficient are fluid visibility, fluid velocity, fluid density and geometry of the surface.
Principles of Instrumentation Measurement Systems for Measurement Voltage is influenced by the pressure coefficient values.
The value of the pressure coefficient is the surface of the geometry including flow variation and cylinder shape.
Conclusion
The conclusions of "The Principles of Instrumentation Measurement Systems for Voltage Measurement" are as follows :
1. Pressure is expressed as a force of broad unity.
2. The Principle of Measurement Instrumentation System of Pressure for Voltage Measurement can be measured through :
➩ Absolute pressure
➩ Differential Pressure
➩ Pressure measured
3. The actual pressure measurement is more commonly used for measurement statistics calibration.
In this writing I believe there are still many shortcomings so hopefully there is a suggestion to improve this paper.
But apart from that at least the material that existed in this writing can be studied well so as to provide an understanding of the principle of pressure measurement instrumentation system for voltage measurement ..
