See Inside a Vacuum Gauge
Have you ever wondered how vacuum gauges work?
Here is your chance to take a look inside!
The selection of the correct gauge is crucial to know whether the required vacuum is achieved. Therefore, vacuum gauges are decisive quality indicators of your vacuum system.
The videos allow you to take a detailed look at the inner workings and functionality of vacuum gauges.
- Exactly how the physics inside a vacuum gauge work
- How to derive from a measurement principle and "translate" to pressure
Capacitive vacuum gauge
This video focuses on the working principle of a capacitive gauge. You will see how the diaphragm inside the gauge moves depending on the total pressure changes.
Piezo-resistive vacuum gauge
In this video, you find out how the Piezo-resistive vacuum measurement works. You will see how the resistance circuits in the diaphragm of the gauge change depending on the pressure.
Pirani gauge
This video focuses on the working principle of a Pirani gauge. You will see how the heat gets transfered through the vacuum inside the gauge depending on the total pressure. The dependence of the heat transfer as well as pressure on the gas type is also visualized.
Cold cathode vacuum gauge
In this video, you find out how the cold cathode vacuum measurement works. You will see how gas molecules get ionized by high-voltage and a plasma is created.
Hot cathode vacuum gauge
This video focuses on the working principle of a hot cathode gauge. You will see how the gas molecules get ionized by a hot filament.
