INTRODUCTION
The Rosemount® Model 2088 Smart Pressure
Transmitter is an economical addition to the
Rosemount pressure transmitter line of
instruments. The Model 2088 is designed with
reliability, long-term performance, and
maintainability in mind. Model 2088 transmitters
maintain a specification conformance of at least
3s(1). The rugged, reliable performance for which
Rosemount transmitters are famous—coupled with
its smart capabilities —make these transmitters
exceptional values.
Constructed for Safety and Durability
Process Seals
The Model 2088 is designed to operate safely in the
event of damage or failure to the sensor diaphragm.
The electronics compartment is isolated from the
process with two seals. A third seal isolates the field
terminals and conduit entries. The design and
placement of the process seals ensures against
housing pressurization and process contamination of
the conduit system through the field
terminal compartment.
Dual Compartment Housing
The Model 2088 features a dual compartment housing
design pioneered by Rosemount Inc. with the Model
1151 Pressure Transmitter. The dual compartment
design completely isolates the electronics from the
external environment to prevent damage to the
transmitter due to condensation in the conduit system
or humidity in the transmitter environment. A
conduit seal is typically not required to meet electrical
codes. Also, the dual compartment housing ensures
that the field terminals and the conduit system
remain isolated from the process in the event of a
gross sensor module failure.
(1) Sigma (s) is a statistical symbol to designate the standard
deviation from the mean value of normal distribution.
OPERATION
Sensor Module
Pressure applied to an isolating diaphragm is
transmitted to the polysilicon sensor by silicone or
inert fill fluid, as shown in Figure 1. With a gage
pressure transmitter, the reference side of the sensor
is referenced to atmospheric pressure; absolute
pressure transmitters have a sealed
vacuum reference.
Process pressure applied to the sensor creates
a very small deflection of the sensing diaphragm,
which in turn applies strain to a Wheatstone bridge
circuit in the sensor. The change in resistance is
sensed and converted to a digital signal for
processing by the microprocessor.

STANDARD FEATURES OF THE MODEL 2088 TRANSMITTER
Rosemount Inc.
Pressure-203 Model 2088
Electronics Module
The electronics module incorporates ASIC and
surface-mount technology. It accepts the digital
signal from the sensor module, along with the
correction coefficients, then corrects and linearizes
the signal. The output section of the electronics
module converts the digital signal to an analog
output. On the smart version, the output section also
handles communication with the HART®
Communicator, HART-based control system, or the
Asset Management Solutions software.
Data Storage
Configuration Data is stored in nonvolatile
EEPROM memory in the transmitter electronics
module. This data is retained in the transmitter
when power is interrupted, so the transmitter is
functional immediately upon power up.
SOFTWARE FUNCTIONALITY
OF THE MODEL 2088 SMART
HART protocol allows easy access to the
configuration, test, and detailed setup capabilities of
the Model 2088 Smart.
Configuration
The Model 2088 Smart can be configured easily
using a HART Communicator or other HART-based
communications device. Configuration consists of
two parts. First, the transmitter operational
parameters are set, which include:
TAILOR THE MODEL 2088 YOUR
APPLICATION....
• Gage or absolute pressure
• Stainless steel or Hastelloy
®wetted parts
• Silicon or inert oil fill
• Variety of process connections:
½–14 NPT female
RC ½ female
M2031.5male
DIN 16288 G ½ male
• Zero and span setpoints
•Damping
• Engineering unit selection
Second, data can be entered into the transmitter to
allow identification and physical description of the
transmitter. This data includes:
• Tag: 8 alphanumeric characters
• Descriptor: 16 alphanumeric characters
• Message: 32 alphanumeric characters
•Date
• Integral Meter Installation
• Remote Seal Information
In addition to the configurable parameters, the
Model 2088 Smart software contains information that
is not user-changeable. Non-configurable information
includes: transmitter type, sensor limits, minimum
span, fill fluid, isolator material, module serial
number, and transmitter software revision level.
Test
The Model 2088 performs continuous
self-tests. In the event of a problem, the transmitter
activates the user-selected analog output warning.
A HART Communicator or other HART-based
communications device can then interrogate the
transmitter to determine the problem. The
transmitter outputs specific information to the
communicator identifying the problem for fast and
easy corrective action. If an operator believes there
is a loop problem, the transmitter can be directed to
provide specific outputs for loop testing.
...THEN ADD YOUR CHOICE OF OPTIONS:
• Configurable LCD meter
• Integral Manifolds (pre-assembled to the
transmitter and leak checked)
• Remote seals (direct mount and capillary)
• Stainless Steel Mounting Brackets
• Hazardous Area Approvals
• NAMUR-compliant alarm levels
(Smart version only)
