Water (DC = 80) 3.3 ft. (1.0 m)
3.2.10 Insulated tanks
When the Rosemount 5300 is installed in high temperature applications, consider the
maximum ambient temperature. See Temperature limits for details.
Tank insulation should not exceed 4 in. (100 mm) above the top of the process
connection.

Installation and configuration considerations for ESD
systems
Figure 3-15 shows a common example of an Emergency Shutdown (ESD) system in a
separator. High-high and low-low transmitters act as redundant safeguards. They will
trigger emergency shutdowns or redirect flow of the application. In addition, there are one
or several process control units that continuously measure and report the actual level in
the tank to the host system and operators.
The high-high unit will always be empty during normal operation, and will indicate empty
in the host system. The low-low unit will always be full during normal operation, and will
indicate full in the host system as well.
