Transducer Cooling - Air / Inert Gas
If the process temperature is such that the block/dome temperature
would
be between 200 °C and 300 °C without additional cooling, air /
inert gas cooling is
required
to keep the block/dome temperature at or
below 200 °C. A pressure of 5-10 psi @ 0.25 CFM is generally sufficient
to keep block/dome temperatures at a suitable level (at or below 200 °C.)
Adjust the air / inert gas pressure to the minimum pressure required to
maintain the transducer dome/block at or below 200 °C.
Air / inert gas cooling connection locations on the transducer dome are
shipped with plugs installed in place of the required stainless-steel
fittings to prevent exposure of the transducer block to contaminants
and moisture (including ambient air) during shipping.
3.8.1.1 Installing the 1/8” NPT Air / Inert Gas Cooling
Fittings
•
Remove the cooling port shipping plugs from locations
B in Figure 3.12.
BOTH
shipping plugs must be removed
and the fittings installed for proper cooling airflow.
•
Use Teflon tape on the
1/8” NPT
stainless-steel fitting
threads and install the fittings in the dome at the
locations from where the plugs were removed
(positions marked B) in Figure 3.12.
•
Connect regulated moisture-free cooling air / inert gas
to one of the cooling fittings B via flexible hose or tubing.
Figure 3.12: Location of Air / Inert Gas Cooling Fittings
An example of an air / inert gas cooling instillation is shown
in Figure 3.13. An outlet hose is optional. No stress should
be applied to the transducer from these cooling lines.
