Standard atmospheric pressure: 101.325kPa
Local atmospheric pressure: the actual local atmospheric pressure, generally between 90-120kPa
Absolute pressure:the pressure of absolute vacuum, it is absolute pressure 0
Gauge Pressure:The pressure value relative to the local atmospheric pressure.Generally, no special instructions are given, and the marked pressures are gauge pressures.
Absolute pressure:Pressure value relative to absolute pressure.Generally used in the measurement of vacuum degree.
Differential Pressure:The pressure difference between two pressures.Generally used for pressure comparison between two tanks or pipelines
