The purpose of this technical note is to provide a better understanding of vacuum, including an explanation of vacuum and description of vacuum measuring instrumentation.

In this tech note, we explore:

  • Fundamentals of gas pressure.
  • Wide range of pressure measurement methods including direct pressure measurement, Capacitance Manometers, Piezo-Resistive Gauges, indirect pressure measurement, Pirani Gauges, and Ionization Gauges.
  • Vacuum gauge and transducer products that can be used individually or combined to provide a wide variety of pressure measurement options.
  • How to choose the right type of pressure sensor for applications with different range, accuracy, and material requirements.
