Revision 13 ST 700 SmartLine Pressure Transmitters User’s Manual Page 5
2.1.2 Functional Characteristics
The ST 700 standard transmitter measures process pressure and provides a proportional analog
4 to 20mA output to the measured process variable (PV). Available output communication protocols
include Honeywell Digitally Enhanced (DE), HART
, and FOUNDATION
TM
Fieldbus.
The standard display is only available on HART transmitters.
An optional 3-button assembly is available to set up and make adjustments to the transmitter. In
addition, a Honeywell Multi-Communication (MC) Toolkit (not supplied with the transmitter) can
facilitate setup and adjustment procedures. Certain adjustments can be made through an Experion
Station or a Universal Station if the transmitter is digitally integrated with Honeywell’s Experion or
TPS/TDC 3000 control system.
The standard display menu is implemented as one long single-level menu and will “wrap around”
when it reaches the start or end of the menu. The standard display uses an optional two-button
assembly to set up and make adjustments to the transmitter.
2.2 ST 700 Standard Transmitter Nameplate
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. The DP model provides one additional entry (7 vs. 6) in
the meter body Selections (Table I) to accommodate the static pressure rating.

You can readily identify the series and basic transmitter type from the third and fourth digits in the
key number. The letter in the third digit represents one of these basic transmitter types:
