1 Pa Tryck från en husfluga som står på ett frimärke i vakuum (ungefär). 10 Pa Tryck från en vattenpelare på 1 millimeter. 100 Pa Tryck från 1 cm vattenpelare. Smärttröskel. For reference, most vacuum cleaners can generate a suction pressure of 20 kPa. This simply means the pressure inside the vacuum hose is 20 kPa less than the normal atmospheric pressure of 100 kPa.

If you have a typical vacuum furnace it is normal to have at least three electronic vacuum gauge heads mounted on the system to monitor the level of vacuum at selected positions. These gauge heads send signals back to the controls system and the vacuum readings are used to ensure that the vacuum pumps are working correctly and that the process chamber is at the correct low pressure (vacuum) for the specific process.

1 L = 0.035315 ft3 1/sec = 60/min F = 60 × 0.035315 × airflow (L/sec)> = 2.1189 × airflow (L/sec)> Also some vacuum cleaners use kPa or mbar as vacuum cleaner suction measurement. 1 pressure in inches of water ≈ 2.49 mbar ⇒ 1 mbar = 1/2.49 inH2O Setra's Vacuum Sensors; Vacuum Pressure. By definition, vacuum is a space that is partially exhausted (as to the highest degree possible) by artificial means (such as an air pump). This definition is referring to a high or hard vacuum. Figure 1 illustrates that relationship of absolute and gauge pressure with 0 PSIA equal to a high or hard vacuum.
