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 gauge2.1 [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 gap piston gauge controledclearancepistongauge Using the second pressure source (also known as the external pressure) exerted pressure on the outer wall of the cylinder, with a first pressure source (also known as the Closely with the pressure) the pressure applied to the control system required clearance between the piston and the piston pressure measurement pressure ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJF 1008-2008_English be delivered?Answer: Upon your order, we will start to translate JJF 1008-2008_English as soon as possible, and keep you informed of the progress.
