Consulting
GFV Associates provides special, custom measurement services for vacuum equipment manufacturers and their customers.
Recent projects include:
Recent projects include:
- Measurement of the conductance of large diameter butterfly valves. The calibration depended on our ability to provide precise, traceable pressure measurements at high vacuum.
- Measurement of the response of a variety of thermal effect gauges, that is Pirani and thermocouple gauges, mounted in various positions. We developed computer output to display the large amount of data recorded.
- Speed of response measurement of TC based gauges. For this project we developed a circuit to drive a high-speed valve to provide step pressure increases.
- Measurement of the sensitivity of newly designed cold cathode gauges. We developed a method for adjusting the sensitivity to a standard value by magnet positioning.
- Life tests of ion tubes.
