A vacuum gauge is an instrument used to measure pressure in a vacuum environment . (depression) Essentially, it works by measuring the force needed to attract a diaphragm or spring to a specific position. This is accomplished through a sensor that measures the deflection of the diaphragm or spring and converts it into a pressure reading. The units in which vacuum is usually measured are Bar, millibar, atmospheres, psi or mmHg.
The most common sizes of vacuum gauges can be, diameter 40, 50, 63, 100 and 160 mm. They can have a glycerin bath to dampen measurements and vibrations. Glycerin is a transparent, viscous liquid that has a high density and low evaporation.
Due to their physical properties, vacuum gauges are used in a variety of applications where it is important to measure and control pressure in a vacuum environment.
Some of the common applications of vacuum gauges include:
- Electronic Device Manufacturing: Vacuum gauges are used in the manufacturing of semiconductors and other electronic devices to monitor pressure in layer deposition and layer removal processes.
- Vacuum industry: Vacuum gauges are used in the vacuum industry to monitor the pressure in vacuum chambers used in research and the manufacture and use of suction cups.
- Aerospace Industry: Vacuum gauges are used in the aerospace industry to measure pressure in vacuum chambers used to simulate space conditions.
- Scientific Research: Vacuum gauges are used in scientific research to measure pressure in physics, chemistry and biology experiments.
- Medicine: Vacuum gauges are used in medicine to measure pressure in vacuum chambers used in wound treatment and blood collection.
It is important to note that vacuum measurement can be a complicated process, as even small leaks can significantly affect measurements. Additionally, proper calibration and maintenance are essential to ensure the accuracy and reliability of vacuum gauges.
Overall, vacuum gauges are important tools in any application that requires the precise measurement and control of pressure in a vacuum environment.
