Mounting Convectron
Gauges
• Cleanliness pays. Keep the port cover in place until moments before
installation.
• For proper operation above about 1 Torr, install Mini-Convectron
Modules with the gauge axis horizontal (see Figure 2-2). Although the
gauge will read correctly below 1 Torr when mounted in any position,
erroneous readings will result at pressures above 1 Torr if the gauge axis
is not horizontal.
• Vibration causes convection cooling of the sensor and will result in high
pressure readings. Mount Mini-Convectron
Modules where they will not
vibrate excessively.
• Orient the gauge to prevent condensation of process vapors on the
internal surfaces through line-of-sight access to its interior. If vapor
condensation is likely, orient the port downward to help liquids drain out
(see Figure 2-2).

Environment
To minimize temperature effects, locate pressure gauges away from internal
and external heat sources, in an area where the ambient temperature is
reasonably constant.
