Section 2: Installation Considerations
Product Data Sheet for more information. The ambient temperature is affected by the process
temperature. Figure 2-11 shows the ambient temperature vs. process temperature.
Figure 2-11. Ambient temperature vs. process temperature
The final maximum ambient temperature rating depends on the type of approval.
In high temperature applications, the ambient temperature limit of the electronics may be
exceeded when mounted close to the vessel. To prevent this, the remote connection described
in the next section should be considered.
2.3.6 Remote housing
A remote housing connection can be used with Rosemount 5300 Series Superior Performance
GWR transmitters to enable reliable measurement in environments where very high ambient
temperatures or excessive vibrations exist at the mounting location of the vessel. It enables the
transmitter electronics to be mounted away from the probe, such as to lower the ambient
temperature, or to place the housing in a better location, for example to be able to read the
display, or enable installation in tight spaces.
The remote housing connection is specified to handle 302 °F (150 °C). The cable used is an SST
flexible armored coaxial cable which is delivered with a mounting bracket for wall or pipe
The remote housing connection is available in lengths of 3.2 ft (1 m), 6.5 ft (2 m), or 9.8 ft (3 m).
