Insight into vacuum gauges: 5 descriptive explanatory videos
Take a look inside a vacuum gauge: Pfeiffer Vacuum publishes easy-to-understand videos that explain how to choose the right measurement principle
To help you select the right measurement principle, Pfeiffer Vacuum has created helpful explanatory videos that provide a detailed insight into the inner workings and functionality of vacuum gauges.
Our vacuum gauges are important quality indicators. Modern technologies allow total pressure measurement from atmospheric pressure to ultra-high vacuum, precisely covering all vacuum ranges. In five videos we explain the relevant measuring principles: From capacitive measurement to piezo, Pirani, cold cathode and hot cathode."
The video on Pirani vacuum measurement explains the functional principle of the heat conduction vacuum meter.
The video on cold cathode vacuum measurement shows how gas molecules are ionised by high voltage and a plasma is created. The hot cathode vacuum measurement video shows the operating principle of a hot cathode transmitter and how the gas molecules are ionised by electrons emitted from a hot filament.
