Station if the transmitter is digitally integrated with Honeywell’s Experion or TPS/TDC 3000 control
system.
1.3 ST 800 Transmitter Name Plate
The transmitter nameplate mounted on the bottom of the electronics housing (see Figure 1) lists its model
number, physical configuration, electronics options, accessories, certifications, and manufacturing
specialties. Figure 3 is an example of a typical Gauge Pressure (GP) or Atmospheric Pressure (AP)
transmitter name plate. The model number format consists of a Key Number with several table selections.
The Differential Pressure (DP), Absolute Pressure (AP), and Gauge Pressure (GP) name plates are
essentially the same. However, the DP provides one additional entry (7 vs. 6) in the meter body Selections
(Table I) to accommodate the static pressure rating.

1.4 Safety Certification Information
An “approvals” name plate is located on the bottom of the electronics housing assembly; see Figure 1 for
exact location. The approvals name plate contains information and service marks that disclose the
transmitter compliance information. Refer to Appendix C of this document for safety certification
requirements and details.
1.5 Transmitter Adjustments
Zero and Span adjustments are possible in ST 800 SmartLine pressure transmitters with the optional
three-button assembly located at the top of the Electronic Housing (see Figure 2).
You can also use the Honeywell Versatilis Configurator or other third-party handheld to make any
adjustments to an ST 800 SmartLine pressure transmitter. Alternately, certain adjustments can be made
through the Experion or Universal Station if the transmitter is digitally integrated with a Honeywell
Experion or TPS system.
