13.1.2 Functional Characteristics
Functionally, the Transmitter measures process pressure and outputs a signal proportional to the
measured process variable (PV). Available output communication protocols include analog 4 to
20mA, HART.
Integrated 2-push buttons are available on Standard Display 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 if the Transmitter is digitally integrated with Honeywell’s Experion.
An optional external 2-button assembly is also available for configuring / adjusting the Transmitter.
The two external buttons are used for navigation of Standard Display or for
setting zero, span and zero correct where standard display is not
connected.
13.2 Series, Model and Number
The Transmitter nameplate mounted on the top of the Electronics Housing (see Error! Reference
ource not found. 2 lists the model number, physical configuration, electronics options, accessories,
certifications, and manufacturing specialties. Figure 17 is an example of a typical Differential
Pressure (DP) or Gauge Pressure (GP) or Absolute 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 characters) in the Meter Body Selections
(Table I) to accommodate the static pressure rating.

–Typical BasicTransmitter Name Plate Information
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:

A = Absolute Pressure

D = Differential Pressure

F = Flange Mounted

G = Gauge Pressure

R = Remote Seals

Guide provided as a separate document.
