Technical Information
Installation
The UHV-24 and UHV24p Nude Ionization Gauges can be operated with any ion
gauge control unit capable of supplying the necessary operating voltages and
currents. Degassing of this gauge is by electron bombardment of the grid.
To install the gauge:
1
Remove the metal sleeve protecting the collector wire.
2
Mount the nude Ionization gauges in any position.
Install the gauge in a relatively open space to reduce wall outgassing due to
NOTE
localized heating by the filament.
When the gauges are mounted horizontally, position the filaments to the side of the
grid rather than below or above it so that a slight vertical movement of the grid or
filament does not change their relative spacing.
