Vacuum table refers to the vacuum or pressure gauge?
In fact, the vacuum meter, as the name suggests, is the reading of the vacuum. Here's a brief look at all the pressures:G P (table): pressure from pressure gauge read, it is the relative pressure by the atmospheric pressure as the benchmark value.Absolute pressure P (absolute): the actual pressure value based on absolute vacuum.The relationship between the absolute pressure gauge,P (absolute) =P (atmospheric pressure) +P (table)If the P (must) <P (atmospheric pressure), P (table) = - (P - P, the atmospheric pressure is lower than the vast) pressure gauge called vacuum. The higher the vacuum, the smaller the pressure.
Vacuum negative pressure.
