Vacuum Measurement

Transducers

Varian offers many transducer technologies for a wide variety of vacuum applications. The selection of an appropiate vacuum gauge for a particular application depends upon many factors. Some of the factors that should be considered are:

• operating pressure ranges
• repeatability of measurement
• mounting orientation
• accuracy of measurement
• transducer ruggedness
• the presence of chemically-reactive gas species
• sensitivity to stray magnetic or electromagnetic fields.

Varian’s wide range of transducers include:

• Thermocouple
• Convection
• Cold cathode
• Inverted magnetron
• Hot filament
