CONSIDERATIONS
General Electrical temperature sensors, such as resistance temperature detectors
(RTDs) and thermocouples (T/Cs), produce low-level signals proportional to
temperature. The 3144P transmitter converts low-level signals to HART or
FOUNDATION fieldbus signals. This signal is then transmitted to the control
room via two power/signal wires.
Electrical Proper electrical installation is essential to prevent errors due to sensor lead
resistance and electrical noise. The current loop must have between 250 and
1100 ohms resistance for HART communications. Refer to Figure 2-10 on
page 2-11 for sensor and current loop connections. FOUNDATION fieldbus
devices must have proper termination and power conditioning for reliable
operation. Shield cables must be used for FOUNDATION fieldbus and the shield
may only be grounded in one place.

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 1-1 describes
the relationship between housing temperature rise and extension length.
Figure 1-1. 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.
Moist or Corrosive
Environments
The 3144P temperature transmitter has a highly reliable dual compartment
housing designed to resist moisture and corrosion. 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 properly
installed. In humid environments, however, it is possible for moisture to
accumulate in conduit lines and drain into the housing.

NOTE
Each transmitter is 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: Product Certifications). Verify that
the operating atmosphere of the transmitter is consistent with the hazardous
locations certifications. 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).
Mounting Take into account the need for access to the transmitter when choosing an
installation location and position.
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.
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).
Software Compatibility Replacement transmitters may contain revised software that is not fully
compatible with the existing software. The 375 Field Communicator and AMS
software containing device descriptors for the 3144 and 3244MV before
December 2001 do not fully support the new features of the 3144P. The
Device Descriptors (DD) are available with new communicators or can be
loaded into existing communicators at any Emerson Process Management
Service Center.

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.
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 375 Field 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.

COMMISSIONING The 3144P must be configured for certain basic variables to operate. In many
cases, all of these variables are pre-configured at the factory. Configuration
may be required if the configuration variables need to be changed.
Commissioning consists of testing the transmitter and verifying transmitter
configuration data. Rosemount 3144P transmitters can be commissioned
either before or after installation. Commissioning the transmitter on the bench
before installation using a 375 Field Communicator or AMS ensures that all
transmitter components are in working order.
For more information on using the Field Communicator with the 3144P
transmitter, see “HART Commissioning” on page 3-1. For more information on
using the 3144 with Foundation fieldbus, see “Foundation Fieldbus
Configuration” on page 4-1.

Setting the Loop to
Manual
When sending or requesting data that would disrupt the loop or change the
output of the transmitter, set the process application loop to manual. The 375
Field Communicator or AMS will prompt you to set the loop to manual when
necessary. Acknowledging this prompt does not set the loop to manual. The
prompt is only a reminder; set the loop to manual as a separate operation.

Table 2-1. Transmitter Switch
Locations.
Write Protect Switch (HART and FOUNDATION Fieldbus)
The transmitter is equipped with a write-protect switch that can be positioned
to prevent the accidental or deliberate change of configuration data.
Alarm Switch (HART)
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 or NAMUR-compliant operation. These
values are also custom-configurable in both the factory and the field using the
HART Communications. The limits are
•21.0≤I ≤23 for high alarm
•3.5≤I ≤3.75 for low alarm
Table 2-2. Values for standard
and NAMUR operation
Simulate Switch (FOUNDATION Fieldbus)
Simulate switch is used to replaces the channel value coming from the
Sensor Transducer Block. For testing purposes, it manually simulates the
output of the Analog Input Block to a desired value.
MOUNTING 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 2-3, is advisable. Remove the terminal compartment
cover periodically and inspect the transmitter for moisture and corrosion.

Figure 2-3. Recommended
Mounting with Drain Seal
If mounting the transmitter directly to the sensor assembly, use the process
shown in Figure 2-4. If 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 G1/2
threads are provided by an adapter). Make sure only qualified personnel
perform the 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.
