2.1.1 Physical Characteristics
As shown in
Figure 1 , the ST 700 is packaged in two major assemblies: the Electronics Housing and
the Meter Body. The elements in the Electronic Housing respond to setup commands and execute the
software and protocol for the different pressure measurement types.
Figure 2 shows the assemblies in
the Electronics Housing with available options.
The Meter Body provides connection to a process system. Several physical interface configurations
are available, as determined by the mounting and mechanical connections. Refer to the
ST 700
SmartLine User’s Manual , Document# 34-ST-25-44 for installation and wiring details.
