What types of vacuum gauges are there?
CIXI is a professional vacuum gauge manufacturer that can provide various types of precision vacuum gauges. Today CIXIFM winny will introduce to you the types of vacuum gauges.
There are many types of vacuum gauges, which can be divided into different types according to different classification standards.
According to the different physical mechanisms utilized by the measurement principle, vacuum gauges can be divided into the following three categories:
Exploiting mechanical properties: such as Bourdon meters and thin film capacitance meters. Among them, the Bourdon vacuum gauge is a vacuum gauge made by utilizing the stretching phenomenon of vacuum tubes.
A thin copper tube measures air pressure under the action of gas pressure. Its measurement range is generally 100Pa to 1atm. Thin film capacitance rules are extrapolated changes
Air pressure is measured by measuring the change in capacitance caused by a metal diaphragm deforming under different pressures. The advantage of this instrument is its high sensitivity.
Exploiting gas dynamic effects: e.g. Pirani resistance meters and thermocouple meters. Pirani resistance gauge, also known as thermal resistance vacuum gauge, works on
The relationship between resistance and temperature.
Utilizing charged particle effects: such as hot cathode ionization meters and cold cathode ionization meters. A hot cathode ionization vacuum gauge is a vacuum gauge that utilizes hot electrons
Gas molecules are ionized in a vacuum and the degree of vacuum is measured indirectly by measuring the resulting ion current.
In addition, according to the scope of use, vacuum gauges can also be divided into absolute vacuum gauges and relative vacuum gauges. Absolute vacuum gauge is a vacuum gauge
The force of the "wall" or "membrane" is used to produce displacement changes to indicate pressure. Relative vacuum gauges use heat conduction or ionization phenomena to indirectly measure vacuum.
In addition, there are some other types of vacuum gauges, such as static liquid level vacuum gauges, elastic element vacuum gauges, thermal conductivity vacuum gauges, thermal conductivity vacuum gauges, etc.
Radiation vacuum gauges, discharge tube indicators and viscosity vacuum gauges.
In summary, different types of vacuum gauges differ in their principles and characteristics, so you need to choose the appropriate type based on the needs of your specific application.
