Usually on the physics of pressure, say things that occurred in two objects to touch the surface of the role of the force, there is force on solid and liquid gas straight appearance, and the appearance of the solid liquid on the straight force.
The atmospheric pressure is due to the earth's gravitational effect, and with the atmospheric pressure is high change. The influence of the atmospheric column weight is also affected by changes in the density, the density of air is larger, mass per unit volume of air in the greater the pressure generated is also increasing.
The pressure of the pressure gauge is the surface pressure, also known as the relative pressure, which means the difference between the real pressure and the atmospheric pressure in the internal measurement
Here the vacuum gauge vacuum pressure gauge is a pressure measurement commonly used in many fields, there are some applications of the vacuum pressure gauge and vacuum gauge for the measurement of steel, copper, no explosion danger without crystallization, solidification of liquid, gas and so on.
Taiwan is the pressure calibration check pressure (differential pressure) transmitter, precision pressure gauge, ordinary pressure gauges, pressure switches and other auxiliary equipment instrumentation, with pressure regulator, complete testing equipment. For the calibration of pressure transmitter and pressure sensor, intelligent pressure calibrator measuring their output, test instrument control system the pressure reaches the required pressure, or the pressure transmitter software reads pressure sensor signal values, the values and the standard signal values calculated show error. After the completion of the verification error in data processing and save calculation error data, finally display and print the error data table and test results.
The pressure and gravity, pressure is caused by the two bodies in contact with each other extrusion deformation, in accordance with the division of nature force, pressure force; gravity is due to the ground near earth objects by attraction
Liquid pressure, in the bottom of the liquid container, the inner wall, the interior, the pressure generated by the liquid is called the liquid pressure, referred to as hydraulic pressure
