• G01L 21/02 having a compression chamber in which gas, whose pressure is to be measured, is compressed
• G01L 21/08 by measuring variations in the transmission of acoustic waves through the medium, the pressure of which is to be measured
• G01L 21/10 by measuring variations in the heat conductivity of the medium, the pressure of which is to be measured
• G01L 21/16 by measuring variation of frictional resistance of gases
• G01L 21/26 by making use of radiometer action, i.e. of the pressure caused by the momentum of molecules passing from a hotter to a cooler member; Vacuum gauges of the Knudsen type
• G01L 21/30 by making use of ionisation effects
