2.1 Installation considerations
2.1.1 General
Electrical temperature sensors, such as resistance temperature detectors (RTDs) and
thermocouples (T/Cs), produce low-level signals proportional to temperature. The
Rosemount X-well™ 3144P Temperature Transmitter converts low-level signals to HART
or FOUNDATION™ Fieldbus and then transmits the signals to the control system via two
power/signal wires.
®
2.1.2
2.1.3
Electrical
Proper electrical installation is essential to prevent errors due to sensor lead resistance and
electrical noise. For HART communications, the current loop must have between 250 and
1100 ohms resistance. Refer to for sensor and current loop connections. Foundation
Fieldbus devices must have proper termination and power conditioning for reliable
operation. Shielded cables must be used for Foundation Fieldbus and may only be
grounded in one place.
Temperature effects
Temperature effects
The transmitter will operate within specifications for ambient temperatures between –40
and 185 °F (–40 and 85 °C). Since 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 using additional thermowell lagging, an extension nipple, or
a remote mounting configuration to isolate the transmitter from the process. Figure 2-1
details the relationship between housing temperature rise and extension length.
Figure 2-1: Transmitter Housing Temperature Rise versus Extension Length for a Test
Installation
Reference Manual 11
Installation
December 2019 00809-0100-4021
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, if 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-in (91.4 mm)
yields a housing temperature rise (R) of 22 °C (72 °F), providing a safety margin of 23 °C
(73 °F). A 6.0-in.(152.4 mm) extension length (R = 10 °C [50 °F]) offers a higher safety
margin (35 °C [95 °F]) and reduces 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.
Reference Manual
2.1.4
2.1.5
Moist or corrosive environments
The Rosemount 3144P 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 with 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
according to all applicable installation codes, and approval and installation drawings (see
Rosemount 3144P Product Data Sheet). 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 approval type(s) used.
Location and position
When choosing an installation location and position, take access to the transmitter into
account.
Terminal side of electronics housing
Mount the transmitter so the terminal side is accessible, allowing adequate clearance for
cover removal. Best practice is to mount the transmitter with the conduit entries in a
vertical position to allow for moisture drainage.
Circuit side of electronics housing
Mount the transmitter so the circuit side is accessible, providing adequate clearance for
cover removal. Additional room is required for LCD display installation. The transmitter
may be mounted directly to or remotely from the sensor. Using optional mounting
12 Rosemount 3144P

00809-0100-4021 December 2019
brackets, the transmitter may be mounted to a flat surface or a 2.0-in. (50.8 mm)
diameter pipe (see Mounting).
2.1.6 Software compatibility
Replacement transmitters may contain revised software that is not fully compatible with
the existing software. The latest device descriptors (DD) are available with new Field
Communicators or they can be loaded into existing communicators at any Emerson
Service Center or via the Easy Upgrade process. For more information on upgrading a Field
Communicator, see HART Commissioning.
To download new device drivers, visit Emerson.com/Rosemount/Device-Install-Kits.
2.2 Commissioning
The transmitter must be configured for certain basic variables to operate. In many cases,
these variables are pre-configured at the factory. Configuration may be required if the
variables need to be changed.
Commissioning consists of testing the transmitter and verifying transmitter configuration
data. Transmitters can be commissioned either before or after installation. Commissioning
the transmitter on the bench before installation using a Field Communicator or AMS
Device Manager ensures that all transmitter components are in working order.
For more information on using the Field Communicator with the transmitter, see HART
Commissioning. For more information on using the Rosemount 3144 with FOUNDATION
Fieldbus, see FOUNDATION Fieldbus Configuration.

2.2.1 Setting the loop to manual
Set the process application loop to manual when sending or requesting data that would
disrupt the loop or change the output of the transmitter. The Field Communicator or AMS
Device Manager will prompt to set the loop to manual, when necessary. Acknowledging
the prompt does not set the loop to manual, it is only a reminder. Setting the loop to
manual is a separate operation.

Alarm switch (HART Protocol)
An automatic diagnostic routine monitors the transmitter during normal operation. If the
diagnostic routine detects a sensor failure or an electronics failure, the transmitter goes
into alarm (high or low, depending on the position of the failure mode switch).
Reference Manual 15
Installation Reference Manual
December 2019 00809-0100-4021
The analog alarm and saturation values used by the transmitter depend on whether it is
configured to standard or NAMUR-compliant operation. These values are also customconfigurable in both the factory and the field using the HART Communications. The limits
are:
• 21.0 ≤ I ≤ 23 for high alarm
• 20.5 ≤ I ≤ 20.9 for high saturation
• 3.70 ≤ I ≤ 3.90 for low saturation
• 3.50 ≤ I ≤ 3.75 for low alarm
Note
A 0.1 mA separation between low saturation and low alarm is required.
Table 2-1: Values for Standard and NAMUR Operation
Standard operation (factory default) NAMUR-compliant operation
Fail high 21.75 mA ≤ I Fail high 21.0 mA ≤ I
High saturation 20.5 mA High saturation 20.5 mA
Low saturation 3.9 mA Low saturation 3.8 mA
Fail low I ≤ 3.75 mA Fail low I ≤ 3.6 mA
Simulate switch (FOUNDATION Fieldbus)
Simulate switch is used to replace 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.
2.3 Mounting
If possible, the transmitter should be mounted 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.

F. Poured conduit seal (where required)
If mounting the transmitter directly to the sensor assembly, use the process shown in
Figure 2-6. If mounting the transmitter apart from the sensor assembly, use conduit
between the sensor and transmitter. The transmitter accepts male conduit fittings with ½
–14 NPT, M20 × 1.5 (CM 20), PG 13.5 (PG 11), or JIS G ½ threads (M20 × 1.5 (CM 20),
PG 13.5 (PG 11), or JIS G ½ 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. Pipestand mounting, using one of the optional mounting brackets, is recommended for use in
high-vibration conditions.
2.4 Installation
Installation is to be performed by qualified personnel. No special installation is required in
addition to the standard installation practices outlined in this document. Always ensure a
proper seal by installing the electronics housing cover(s) so that metal contacts metal.
The loop should be designed so the terminal voltage does not drop below 12 Vdc when
the transmitter output is 24.5 mA.

and use of incorrect sensor will result in inaccurate process temperature calculations. It is
extremely important that the above requirements and installation steps below are
followed to ensure that Rosemount X-well Technology works as specified.
In general, pipe clamp sensor installation best practices shall be followed. See Rosemount
0085 Pipe Clamp Sensor Quick Start Guide with Rosemount X-well Technology specific
requirements noted:
1. Mount transmitter directly on pipe clamp sensor in order for Rosemount X-well
Technology to properly function.
2. Install assembly away from dynamic external temperature sources such as a boiler
or heat tracing.
3. Ensure for the pipe clamp sensor tip to make direct contact with the pipe surface for
Rosemount X-well Technology. Moisture build-up between sensor and pipe surface,
or sensor hang-up in assembly can cause inaccurate process temperature
calculations. Refer to installation best practices in Rosemount 0085 Pipe Clamp
Sensor Quick Start Guide to ensure proper sensor to pipe surface contact.
4. Insulation ½-in. thick minimum with a R-value of > 0.42 m² × K/W) is required over
the sensor clamp assembly and sensor extension up to transmitter head to prevent
heat loss. Apply a minimum of six inches of insulation on each side of the pipe
clamp sensor. Care should be taken to minimize air gaps between insulation and
pipe.
Reference Manual
2.4.4
Note
DO NOT apply insulation over transmitter head as it will result in longer response
times and may damage transmitter electronics.
5. Although it will come factory configured as such, ensure that pipe clamp RTD
sensor is assembled in 4-wire configuration.

2.4.5 LCD display
Transmitters ordered with the LCD display option (code M5) are shipped with the LCD
display installed. After-market installation of the LCD display on a conventional transmitter
requires a small instrument screwdriver and the LCD display kit, which includes:
• LCD display assembly
• Extended cover with cover O-ring in place
• Captive screws (quantity 2)
• 10-pin interconnection header
To install the LCD display:
Procedure
1. If the transmitter is installed in a loop, set the loop to manual (HART)/out-of-service
(FOUNDATION Fieldbus) mode and disconnect the power.
2. Remove the housing cover from the electronics side of the transmitter. Do not
remove the transmitter covers in explosive atmospheres with a live circuit.
3. Ensure that the transmitter write protect switch is set to the Off position. If
transmitter security is On, the transmitter cannot be configured to recognize the
LCD display. If security On is desired, configure the transmitter for the LCD display,
and then install the meter.
4. Insert the interconnection header in the 10-pin socket on the face of the electronics
module. Insert the pins into the electronics LCD display interface.
5. The meter can be rotated in 90-degree increments for easy viewing. Position one of
the four 10-pin sockets on the back of the meter to accept the interconnection
header.
6. Attach the LCD display assembly to the interconnection pins, then thread and
tighten the LCD display screws into the holes on the electronics module.
7. Attach the extended cover; tighten at least one-third turn after the O-ring contacts
the transmitter housing. Both transmitter covers must be fully engaged to meet
explosion proof requirements.
8. Apply power and set the loop to automatic (HART)/in-service (FOUNDATION Fieldbus)
mode.
Once the LCD display is installed, configure the transmitter to recognize the meter
option. Refer to LCD display options or LCD display transducer block (index number
1200) (FOUNDATION Fieldbus).
Note
Observe the following LCD display temperature limits:
Operating: –40 to 185 °F (–40 to 85 °C)
Storage: –76 to 185 °F (–60 to 85 °C)

2.4.6 Multichannel installation (HART/4–20 mA only)
Several transmitters can be connected to a single master power supply (see figure below).
In this case, the system may be grounded only at the negative power supply terminal. In
multichannel installations, where several transmitters depend on one power supply and
the loss of all transmitters would cause operational problems, consider an uninterrupted
power supply or a back-up battery. The diodes shown in Figure 2-10 prevent unwanted
charging or discharging of the back-up battery.

2.5 Wiring
2.5.1 HART/4–20 mA
Field wiring
The power to the transmitter is supplied over the signal wiring. Signal wiring does not
need to be shielded, but twisted pairs should be used for best results. Do not run
unshielded signal wiring in conduit or open trays with power wiring or near heavy electrical
equipment because high voltage may be present on the leads and may cause an electrical
shock.
Note
Do not apply high voltage (e.g., AC line voltage) to the power or sensor terminals, since
high voltage can damage the unit.

Reference Manual Installation
00809-0100-4021 December 2019
Procedure
1. Remove the transmitter covers.
Do not remove the transmitter covers in an explosive atmosphere when the circuit
is live.
2. Connect the positive power lead to the terminal marked “+” and the negative
power lead to the terminal marked “–” as shown in Figure 2-11.
Crimped lugs are recommended when wiring to screw terminals.
3. Tighten the terminal screws to ensure good contact is made. No additional power
wiring is required.
4. Replace the transmitter covers making sure both transmitter covers are fully
engaged to meet explosion-proof requirements.
Power/current loop connections
Use copper wire of a sufficient size to ensure that the voltage across the transmitter power
terminals does not go below 12.0 Vdc.
1. Connect the current signal leads as shown in Figure 2-13.
2. Recheck the polarity and connections.
3. Turn the power ON.
For information about multichannel installations, refer to Multichannel installation
(HART/4–20 mA only).
Note
Do not connect the power/signal wiring to the test terminal. The voltage present on the
power/signal leads may burn out the reverse-polarity protection diode built into the test
terminal. If the test terminal’s reverse polarity protection diode is burned out by the
incorrect power/signal wiring, the transmitter can still be operated by jumping the current
from the test terminal to the “–” terminal. See Test terminal (HART/4–20 mA only) for use
of the terminal.

RTD or ohm inputs
If the transmitter is mounted remotely from a 3- or 4-wire RTD, it will operate within
specifications, without recalibration, for lead wire resistances of up to 60 ohms per lead
(equivalent to 1,000 ft. of 20 AWG wire). In this case, the leads between the RTD and
transmitter should be shielded. If using only two leads (or a compensation loop lead wire
configuration), both RTD leads are in series with the sensor element, so significant errors
can occur if the lead lengths exceed one foot of 20 AWG wire. For longer runs, attach a
third or fourth lead as described above. To eliminate 2-wire lead resistance error, the 2wire offset command can be used. This allows the user to input the measured lead wire
resistance, resulting in the transmitter adjusting the temperature to correct the error.
When using Rosemount X-well Technology, the Rosemount 3144P Temperature
Transmitter is required to be assembled to a Rosemount 0085 Pipe Clamp RTD Sensor in a
direct mount 4-wire configuration. It can be changed to 3- or 2-wired configuration, if
required, in the field.
Thermocouple or millivolt inputs
For direct-mount applications, connect the thermocouple directly to the transmitter. If
mounting the transmitter remotely from the sensor, use appropriate thermocouple
extension wire. Make connections for millivolt inputs with copper wire. Use shielding for
long runs of wire.
Reference Manual
Note
For HART transmitters, the use of two grounded thermocouples with a dual option
transmitter is not recommended. For applications in which the use of two thermocouples
is desired, connect either two ungrounded thermocouples, one grounded and one
ungrounded thermocouple, or one dual element thermocouple.
2.7 Power supply
HART
An external power supply is required to operate the transmitter (not included). The input
voltage range of the transmitter is 12 to 42.4 Vdc. This is the power required across the
transmitter power terminals. The power terminals are rated to 42.4 Vdc. With 250 ohms
of resistance in the loop, the transmitter requires a minimum of 18.1 Vdc for
communication.
The power supplied to the transmitter is determined by the total loop resistance and
should not drop below the lift-off voltage. The lift-off voltage is the minimum supply
voltage required for any given total loop resistance. See Figure 2-16 to determine the
required supply voltage. If the power drops below the lift-off voltage while the transmitter
is being configured, the transmitter may output incorrect information.
The dc power supply should provide power with less than two percent ripple. The total
resistance load is the sum of the resistance of the signal leads and the load resistance of
any controller, indicator, or related piece of equipment in the loop. Note that the
resistance of intrinsic safety barriers, if used, must be included.
Note
Permanent damage to the transmitter could result if the voltage drops below 12.0 Vdc at
the power terminals, when changing transmitter configuration parameters.

Figure 2-16: Load Limits
Maximum load = 40.8 × (Supply voltage–12.0)
FOUNDATION Fieldbus
Powered over FOUNDATION Fieldbus with standard Fieldbus power supplies, the transmitter
operates between 9.0 and 32.0 Vdc, 11 mA maximum. Transmitter power terminals are
rated to 42.4 Vdc.
Installation
The power terminals on the transmitter are polarity insensitive.
2.7.1
Surges/transients
The transmitter will withstand electrical transients of the energy level usually encountered
in static discharges or induced switching; however, high-voltage transients, such as those
induced in wiring from nearby lightning strikes, can damage both the transmitter and the
sensor.
The integral transient protection terminal block (option code T1) protects against highvoltage transients. The integral transient protection terminal block is available as an
ordered option, or as an accessory.
2.8 Grounding
Sensor shielding
The currents in the leads induced by electromagnetic interference can be reduced by
shielding. Shielding carries the current to ground and away from the leads and electronics.
If the ends of the shields are adequately grounded, only a small amount of current will
actually enter the transmitter.
If the ends of the shield are left ungrounded, voltage is created between the shield and the
transmitter housing and also between the shield and earth at the element end. The
transmitter may not be able to compensate for this voltage, causing it to lose
communication and/or go into alarm. Instead of the shield carrying the currents away
from the transmitter, the currents will now flow through the sensor leads into the
transmitter circuitry where it will interfere with the circuit operation.
