1.2.1 Physical Characteristics
As shown in Figure 1, the ST 800 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, all of which are described
in the "Installation" section of this manual.
