Pressure sensor terminology
Standard pressure
The pressure represented by the atmospheric pressure is greater than the atmospheric pressure, and the pressure less than the atmospheric pressure is called the negative pressure.
Absolute pressure
The absolute vacuum is the standard pressure.
Relative pressure
The size of the pressure for comparing objects (standard pressure).
Atmospheric pressure
Refers to atmospheric pressure. The standard atmospheric pressure (1 atm) corresponds to the pressure of a 760 mm mercury column.
vacuum
Refers to sub-atmospheric pressure conditions. 1 Torr = 1/760 atmosphere (atm).
Detection pressure range
Refers to the sensor pressure range.
Can withstand pressure
When the pressure is restored to the detection pressure, the pressure can not withstand the decline of its performance
