Pressure Measurement
To measure pressures in the lines or at the inputs and outputs of components, a pressure gauge is installed in the line at the appropriate point.
A distinction is made between absolute pressure measurement where the zero point on the scale corresponds to absolute vacuum and relative pressure measurement where the zero point on the scale refers to atmospheric pressure. In the absolute system of measurement, vacuums assume values lower than 1, in the relative system of measurement, they assume values lower than 0.
