GETTING ACQUAINTED
WITH THE
TRANSMITTER
The Rosemount Model 3144P Smart Temperature Transmitter is a
microprocessor-based instrument that accepts input from a wide variety of
sensors and transmits temperature data to a control system or transmitter
interface. The transmitter combines Rosemount reliability with the flexibility of
digital electronics. The transmitter is ideal for applications that require high
performance and/or remote communication.
The Rosemount Model 275 HART®Communicator and AMS software use
HART protocol to interrogate, configure, test, and format the Model 3144P
transmitter as well as other Rosemount microprocessor based instruments.
Communication can be made with the transmitter from the control room,
transmitter site, or across any other two points in the loop provided the loop
contains 250 to 1100 ohms of resistance.
Special dual-sensor features include Hot Backup®, sensor drift alert, first
good, differential and average temperature measurements, and four
simultaneous measurement variable outputs in addition to the analog
output signal.
SOFTWARE
COMPATIBILITY
Replacement transmitters may contain revised software that is not fully
compatible with the existing software in your HART communicator.
Model 275 HART Communicators containing device descriptors for the
Models 3144 and 3244MV before December 2001 do not fully support the
new features of the Model 3144P. The HART Communicator Field Device
Revisions Dev v3, DD v2 should be loaded into the Model 275 HART
Communicator to communicate with the new features of the Model 3144P
(see “Model 3144P and Models 3144 / 3244MV Differences”on page 1-3).

SAFETY MESSAGES Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Information that
potentially raises safety issues is indicated by a warning symbol ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.
Warnings
Explosions could result in death or serious injury:
•Do not remove the transmitter cover in explosive atmospheres when the circuit
is live.
•Before connecting a HART communicator in an explosive atmosphere, make sure
the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
•Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
•Both transmitter covers must be fully engaged to meet explosion-proof
requirements.
Failure to follow these installation guidelines could result in death or serious injury:
•Make sure only qualified personnel perform the installation.
Process leaks could result in death or serious injury:
•Install and tighten thermowells or sensors before applying pressure, or process
leakage may result.
•Do not remove the thermowell while in operation. Removing while in operation
may cause process fluid leaks.
Electrical shock could cause death or serious injury. If the sensor is installed in a
high-voltage environment and a fault or installation error occurs, high voltage may
be present on the transmitter leads and terminals:
•Use extreme caution when making contact with the leads and terminals.

Model 3144P
CONSIDERATIONS
General Electrical temperature sensors, such as resistance temperature detectors
(RTDs) and thermocouples (T/Cs), produce low-level signals proportional to
temperature. The Model 3144P transmitter converts low-level sensor signals
to a standard 4–20 mA dc signal. This current signal is then transmitted to the
control room via two power/signal wires.
Figures 2-6 and 2-7 show recommended mounting configurations for
transmitters and sensor assemblies.
Electrical Proper electrical installation is essential to prevent errors due to sensor lead
resistance and electrical noise. Shielded cable should be used for best results
in electrically noisy environments. The current loop must have between 250
and 1100 ohms in order to communicate with a HART communicator. Refer to
Figure 2-10 on page 2-13 for sensor and current loop connections.
Mechanical Use the following information when preparing the installation site and
selecting transmitter options.
The transmitter may be mounted directly to or remotely from the sensor.
Using optional mounting brackets, the transmitter may be mounted to a flat
surface or to a two-inch diameter pipe (see “Optional Transmitter Mounting
Brackets”on page A-8).
Environmental Temperature Effects
The transmitter will operate within specifications for ambient temperatures
between –40 and 185 °F (–40 and 85 °C). Heat from the process is
transferred from the thermowell to the transmitter housing. If the expected
process temperature is near or beyond specification limits, consider the use of
additional thermowell lagging, an extension nipple, or a remote mounting
configuration to isolate the transmitter from the process. Figure 2-4 describes
the relationship between transmitter housing temperature rise and extension
length.

Figure 2-2. Model 3144P
Transmitter Housing
Temperature Rise versus
Extension Length for a Test
Installation.
Example:
The maximum permissible housing temperature rise (T) can be calculated
by subtracting the maximum ambient temperature (A) from the
transmitter’s ambient temperature specification limit (S). For instance,
suppose A = 40 °C.
T = S - A
T = 85 °C –40 °C
T = 45 °C
For a process temperature of 540 °C (1004 °F), an extension length of 3.6
inches (91.4 mm) yields a housing temperature rise (R) of 22 °C (72 °F),
which provides a safety margin of 23 °C (73 °F). A six-inch extension
length (R = 10 °C (50 °F)) would offer a higher safety margin (35 °C (95
°F)) and would reduce temperature-effect errors but would probably
require extra transmitter support. Gauge the requirements for individual
applications along this scale. If a thermowell with lagging is used, the
extension length may be reduced by the length of the lagging.
CONSIDERING HOUSING
ROTATION
Take into account the need for access to the transmitter when choosing an
installation location and position.
Housing Rotation
The electronics can be rotated up to 90 degrees in either direction to improve
field access to the two compartments.
Terminal Side of Electronics Housing
Mount the transmitter so the terminal side is accessible. Allow adequate
clearance for cover removal. Make wiring connections through the conduit
openings on the bottom of the housing.
Circuit Side of Electronics Housing
Mount the transmitter so the circuit side is accessible. Provide adequate
clearance for cover removal. Additional room is required for LCD installation.

SET THE SWITCHES
Failure Mode Switch The transmitter monitors itself during normal operation with an automatic
diagnostic routine. If the diagnostic routine detects a sensor failure or a failure
in the transmitter electronics, the transmitter goes into alarm (high or low,
depending on the position of the failure mode switch).
The analog alarm and saturation values that the transmitter uses depend on
whether it is configured to standard (by the factory) or NAMUR-compliant
operation. These values are also custom-configurable in both the factory and
the field using the Model 275 HART Communicator. The limits are
•21.0≤I ≤23 for high alarm
• 3.5 ≤I ≤3.75 for low alarm
Table 2-1. Values for standard
and NAMUR operation
Transmitter Security
Switch
The transmitter is equipped with a write-protect switch that can be positioned
to prevent the accidental or deliberate change of configuration data.
Failure Mode and
Security Switch
Locations
The Security and Failure Mode switches are located on the top center of the
electronics module (see Figure 2-3). The electronics module is in the
electronics side of the transmitter housing. For transmitters with LCD meters,
the electronics module is directly behind the LCD meter.
Changing the Position of
the Failure Mode or
Security Switch

MOUNTING AND
INSTALLATION
The transmitter may require supplementary support under high-vibration
conditions, particularly if used with extensive thermowell lagging or long
extension fittings. Pipe-stand mounting, using one of the optional mounting
brackets, is recommended for use in high-vibration conditions.
Moist or Corrosive
Environments
The Model 3144P temperature transmitter has a highly reliable dual
compartment housing designed to resist attack by moisture and corrosives.
The sealed electronics module is mounted in a compartment that is isolated
from the terminal side conduit entries. O-ring seals protect the interior when
the covers are installed. In humid environments, however, it is possible for
moisture to accumulate in conduit lines and drain into the housing.
Proper transmitter installation can ensure optimal operation and service life
and prevent moisture from accumulating in the housing. Refer to Figure 2-4,
and Figure 2-5 before mounting a transmitter.
If possible, mount the transmitter at a high point in the conduit run so moisture
from the conduits will not drain into the housing. The terminal compartment
could fill with water If the transmitter is mounted at a low point in the conduit
run. In some instances, the installation of a poured conduit seal, such as the
one pictured in Figure 2-5, is advisable. Remove the terminal compartment
cover periodically and inspect the transmitter for moisture and corrosion.

NOTE
Each transmitter is clearly marked with a tag indicating the approvals. Install
the transmitter in accordance with all applicable installation codes and
approval and installation drawings (See Appendix B: Hazardous Area
Approvals). Verify that the operating atmosphere of the transmitter is
consistent with the appropriate hazardous locations certifications.
IMPORTANT
Once a device labeled with multiple approval types is installed, it should not
be reinstalled using any of the other labeled approval types. To ensure this,
the approval label should be permanently marked to distinguish the used from
the unused approval type(s).
If you are mounting the transmitter directly to the sensor assembly, use the
process shown in Figure 2-6. If you are mounting the transmitter apart from
the sensor assembly, use conduit between the sensor and transmitter. The
transmitter accepts male conduit fittings with 1/2–14 NPT, M20 ×1.5 (CM 20),
PG 13.5 (PG 11), or JIS G1/2threads (M20 ×1.5 (CM 20), PG 13.5 (PG 11),
or JIS G1/2threads are provided by an adapter). Make sure only qualified
personnel perform the installation.
