Pressure measurement terminology and definitions
Pressure is generally 1 noun
1.1 pressure (on the project called) pressure
Vertical and uniformly acting on the force per unit area.
NOTE. The pressure in physics called "pressure."
1.2 Differential pressure [force] differentialpressure
Related to the difference between any two of the pressure.
1.3 Absolute pressure absolutepressure
In full vacuum pressure as a reference point.
1.4 atmospheric pressure (also known as. Pneumatic) atmosphericpressure
Earth's surface gravity column of atmospheric air pressure generated.
1.5 gauge pressure gaugepressure
The atmospheric pressure as a reference point, is greater than or less than atmospheric pressure.
1.6 n [table] pressure (also known as. positive) positivepressure
The atmospheric pressure as a reference point, a pressure greater than atmospheric pressure.
1.7 negative [Table] pressure (also known as. negative) negativepressure
The atmospheric pressure as a reference point, less than atmospheric pressure.
1.8 Static pressure staticpressure
In the field of research, does not change with time or change over time and slowly varying pressure.
1.9 dynamic pressure dynamicpressure
In the field of research, time-dependent changes in pressure.
1.10 Pressure unit pressureunit
International System of Units unit of pressure is N/m2, also known as Pascal, referred to as "Pa" (in Pa). its
Physical meaning is. 1 Newton vertical force evenly applied pressure on one square meter area produced.
2 piston gauge
2.1 [simple] piston gauge pistongauge
Its use of the piston connecting member and the special weight load of gravity and measured pressure acting on the piston effective area in living
The principle of force generated by the lower end plug made of equilibrium pressure measurement instruments.
2.2 Anti-pressure piston gauge pistongaugewithre-entrantcylinder
Between the piston pressure transmission medium utilizing a pressure gauge reaction to the outer wall of the cylinder in order to achieve the desired piston system
Gap and pressure measurement piston gauge.
2.3 Control
