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
