CAUTION
The products described in this document are NOT designed for nuclear-qualified applications.
Using non-nuclear qualified products in applications that require nuclear-qualified hardware or products may cause inaccurate
readings.
For information on Rosemount nuclear-qualified products, contact your local Emerson Sales Representative.
WARNING
Explosions can result in death or serious injury.
Do not remove the transmitter covers in explosive environments when the circuit is live.
Fully engage both transmitter covers to meet explosion-proof requirements.
Before connecting a 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 the operating atmosphere of the transmitter is consistent with the appropriate hazardous locations certifications.
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
Install and tighten all four flange bolts before applying pressure.
Do not attempt to loosen or remove flange bolts while the transmitter is in service.
Replacement equipment or spare parts not approved by Emerson or use as spare parts could reduce the pressure retaining
capabilities of the transmitter and may render the instrument dangerous.
Use only bolts supplied or sold by Emerson as spare parts.
Improper assembly of manifolds to traditional flange can damage SuperModule™ Platform.
For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt hole) but must not contact
sensor module housing.
2
WARNING
SuperModule and electronics housing must have equivalent approval labeling in order to maintain hazardous location
approvals.
When upgrading, verify SuperModule and electronics housing certifications are equivalent. Differences in temperature class
ratings may exist, in which case the complete assembly takes the lowest of the individual component temperature classes (for
example, a T4/T5 rated electronics housing assembled to a T4 rated SuperModule is a T4 rated transmitter.)
Severe changes in the electrical loop may inhibit HART® Communication or the ability to reach alarm values. Therefore, Emerson
cannot absolutely warrant or guarantee that the correct failure alarm level (HIGH or LOW) can be read by the host system at the
time of annunciation.
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could
be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access
by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility.

2.1Overview
This section contains information on commissioning and tasks that should be performed
on the bench prior to installation.
Instructions for performing configuration functions are given for handheld
communication devices like the Field Communicator or asset management software like
Emerson's AMS Device Manager. For convenience, Field Communicator Fast Key
sequences (where supported) are labeled “Fast Keys” for each software function below the
appropriate headings.
2.1.1
Example software function
The Device Dashboard Fast Keys apply to Device Driver Revision 9 or newer. The HART® 5
with Diagnostics Fast Keys apply to Device Driver Revision 1. The HART 7 Fast Keys apply
to Device Driver Revision 2. Contact Emerson™ or refer to previous reference manuals for
information on older revisions.

ConfigurationReference Manual
June 202100809-0100-4801
2.2Commissioning on the bench
Commissioning consists of testing the transmitter and verifying transmitter configuration
data. Rosemount™ 3051S Pressure 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 all transmitter components are in
working order.
Equipment required to commission on the bench includes a power supply, a milliamp
meter, and a Field Communicator or AMS Device Manager. Wire the equipment as shown
in Figure 2-1. Verify transmitter terminal voltage is between 10.5–42.4 Vdc. To ensure
successful communication, a resistance of at least 250 ohms must be present between the
Field Communicator loop connection and the power supply. Connect the Field
Communicator leads to the terminals labeled “PWR/COMM” on the terminal block.
(Connecting across the “TEST” terminals will prevent successful communication.)
Set all transmitter hardware adjustments during commissioning to avoid exposing the
transmitter electronics to the plant environment after installation. Refer to .
When using a Field Communicator, any configuration changes made must be sent to the
transmitter by using the Send key. AMS Device Manager configuration changes are
implemented when the Apply button is selected.
2.2.1
2.2.2
Setting the loop to manual
Whenever sending or requesting data that would disrupt the loop or change the output of
the transmitter, set the process application loop to manual. The Field Communicator or
AMS Device Manager 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.
Wiring diagrams
Bench hook-up
Connect the bench equipment as shown in Figure Figure 2-1, and turn on the Field
Communicator or log into AMS Device Manager. The Field Communicator or AMS Device
Manager will search for a HART™-compatible device and indicate when the connection is
made. If the Field Communicator or AMS Device Manager fail to connect, it indicates that
no device was found. If this occurs, refer to Troubleshooting.
Field hook-up
Figure Figure 2-1 illustrate wiring loops for a field hook-up with a Field Communicator or
AMS Device Manager. The Field Communicator or AMS Device Manager may be connected
at “PWR/COMM” on the transmitter terminal block, across the load resistor, or at any
termination point in the signal loop. Signal point may be grounded at any point or left
ungrounded.

2.5Check output
Before performing other transmitter on-line operations, review the digital output
parameters to ensure that the transmitter is operating properly and is configured to the
appropriate process variables.
2.5.1Process variables
The process variables for the Rosemount 3051S provide transmitter output, and are
continuously updated. The pressure reading in both engineering units and percent of
range will continue to track with pressures outside of the defined range from the lower to
the upper range limit of the SuperModule™.

square root output option to make analog output proportional to flow. As input
approaches zero, the pressure transmitter automatically switches to linear output in order
to ensure a more smooth, stable output near zero (see Figure 2-14 ).
From 0 to 0.6 percent of the ranged pressure input, the slope of the curve is unity (y = x).
This allows accurate calibration near zero. Greater slopes would cause large changes in
output (for small changes at input). From 0.6 to 0.8 percent , curve slope equals 42 (y =
42x) to achieve continuous transition from linear to square root at the transition point.
Note
If low flow cutoff configuration is desired, use Scaled variable configuration to configure
square root and Re-mapping to map the scaled variable as the primary variable.
Note
If scaled variable is mapped as the primary variable and square root mode is selected,
ensure that transfer function is set to linear. Do not set the transfer function to square root
if square root mode is selected for the primary variable as this would cause the square root
function to be performed twice.

Note
For a flow turn down of greater than 10:1, it is not recommended to perform a
square root extraction in the transmitter. Instead, perform the square root
extraction in the system. Alternatively, you can configure Scaled Variable for square
root output. This configuration allows you to select a low flow cutoff value, which
will work best for the application. If low flow cutoff configuration is desired, use
Scaled variable configuration to configure square root and Re-mapping to map
scaled variable as the primary variable.

Rerange
The Range Values command sets each of the lower and upper range analog values (4 and
20 mA points) to a pressure. The lower range point represents 0 percent of range and the
upper range point represents 100 percent of range. In practice, the transmitter range
values may be changed as often as necessary to reflect changing process requirements.
For a complete listing of range and sensor limits, refer to the Specifications section of the
Rosemount 3051S Series of Instrumentation Product Data Sheet.
Note
Transmitters are shipped from Emerson fully calibrated per request or by the factory
default of full scale (zero to upper range limit.)
Select from one of the methods below to rerange the transmitter. Each method is unique;
examine all options closely before deciding which method works best for your process.
• Rerange with a Field Communicator or AMS Device Manager only.
• Rerange with a pressure input source and a Field Communicator or AMS Device
Manager.
• Rerange with a pressure input source and the local zero and span buttons (option D1).
Note
If the transmitter security jumper/switch is ON, adjustments to the zero and span cannot
be made. Refer to Wiring the device for security information.

ConfigurationReference Manual
June 202100809-0100-4801
Rerange with a Field Communicator or AMS Device Manager
only
The easiest and most popular way to rerange is to use the Field Communicator only. This
method changes the range values of the analog 4 and 20 mA points independently
without a pressure input. This means that when you change either the 4 or 20 mA setting,
you also change the span.
An example for the 4–20 mA HART output:
If the transmitter is ranged so that
4 mA = 0 inH2O, and 20 mA = 100 inH2O,
and you change the 4 mA setting to 50 inH2O using the communicator only, the new
settings are:
4 mA = 50 inH2O, and 20 mA = 100.
Note that the span was also changed from 100 inH2O to 50 inH2O, while the 20 mA
setpoint remained at 100 inH2O.
To obtain reverse output, simply set the 4 mA point at a greater numerical value than the
20 mA point. Using the above example, setting the 4 mA point at 100 inH2O and the 20
mA point at 0 inH2O will result in reverse output.

2.8.1Failure mode alarm and saturation
Rosemount 3051S Transmitters automatically and continuously perform self-diagnostic
routines. If the self-diagnostic routines detect a failure, the transmitter drives the output
to configured alarm values. The transmitter will also drive the output to configured
saturation values if the applied pressure goes outside the 4–20 mA range values.
35
ConfigurationReference Manual
June 202100809-0100-4801
The transmitter will drive its output low or high based on the position of the alarm switch.
See Wiring the device.
Note
The failure mode alarm direction can also be configured using the Field Communicator or
AMS Device Manager if hardware switches are not present. See Alarm and saturation level
configuration.
Rosemount 3051S Transmitters have three configurable options for failure mode alarm
and saturation levels:
• Rosemount (Standard), see Table 2-3.
• NAMUR, see Table 2-4.
• Custom, see Table 2-5.

Per Table 2-5, custom alarm and saturation levels can be configured between 3.4 and 3.9
mA for low values and between 20.1 and 23.0 mA for high values. The following
limitations exist for custom levels:
• Low alarm level must be less than the low saturation level
• High alarm level must be higher than the high saturation level
• High saturation level must not exceed 21.5 mA
• Alarm and saturation levels must be separated by at least 0.1 mA

2.10.2
Burst mode
When configured for burst mode, the Rosemount 3051S provides faster digital
communication from the transmitter to the control system by eliminating the time
required for the control system to request information from the transmitter. Burst mode is
compatible with the analog signal. Because the HART protocol features simultaneous
digital and analog data transmission, the analog value can drive other equipment in the
loop while the control system is receiving the digital information. Burst mode applies only
to the transmission of dynamic data (pressure and module temperature in engineering
units, pressure in percent of range, and/or analog output), and does not affect the way
other transmitter data is accessed.
Access to information other than dynamic transmitter data is obtained through the
normal poll/response method of HART communication. A Field Communicator, AMS
Device Manager or the control system may request any of the information that is normally
available while the transmitter is in burst mode. Between each message sent by the
transmitter, a short pause allows the Field Communicator, AMS Device Manager or a
control system to initiate a request. The transmitter will receive the request, process the
response message, and then continue bursting the data approximately three times per
second.

2.11Multidrop communication
Multidropping transmitters refers to the connection of several transmitters to a single
communications transmission line. Communication between the host and the
transmitters takes place digitally with the analog output of the transmitters deactivated.
Multidrop installation requires consideration of the update rate necessary from each
transmitter, the combination of transmitter models, and the length of the transmission
line. Communication with transmitters can be accomplished with Bell 202 modems and a
host implementing HART protocol. Each transmitter is identified by a unique address and
responds to the commands defined in the HART protocol. Field Communicators and AMS
Device Manager can test, configure, and format a multidropped transmitter the same way
as a transmitter in a standard point-to-point installation.
Note
A transmitter in multidrop mode has the analog output fixed at 4 mA. If a meter is installed
to a transmitter in multidrop mode, it will alternate the display between current fixed and
the specified meter output(s).
The Rosemount 3051S is set to address zero (0) at the factory, which allows operation in
the standard point-to-point manner with a 4–20 mA output signal. To activate multidrop
communication, the transmitter address must be changed to a number from 1 to 15 for
HART Revision 5 or 1 to 63 for HART Revision 7. This change deactivates the 4–20 mA
analog output, setting it to 4 mA. It also disables the failure mode alarm signal, which is
controlled by the upscale/downscale switch/jumper position. Failure signals in
multidropped transmitters are communicated through HART messages.
2.11.1
Changing a transmitter address
To activate multidrop communication, the transmitter poll address must be assigned a
number from 1 to 15, and each transmitter in a multidropped loop must have a unique

Rosemount™ 3051S Quick Start Guide for HART is shipped with every transmitter to
describe basic installation, wiring, and startup procedures. Dimensional drawings for each
Rosemount 3051S Pressure Transmitter variation and mounting configuration are
included in the Rosemount 3051S Series of Instrumentation Product Data Sheet.
Note
The following sections contain installation instructions for many optional features. Only
follow a section's directions if the transmitter being installed comes with the features
described.
3.2Safety messages
Procedures and instructions in this section may require special precautions to ensure the
safety of the personnel performing the operation. Refer to the following safety messages
before performing operations in this section.
WARNING
Explosions
Explosions could result in death or serious injury.
Review the approvals section of this manual for any restrictions associated with a safe
installation.
Before connecting a communicator in an explosive atmosphere, ensure the instruments in
the segment are installed in accordance with intrinsically safe or non-incendive field wiring
practices.
In an explosion-proof/flameproof installation, do not remove the transmitter covers when
power is applied to the unit.
Process leaks
Process leaks may cause harm or result in death.
Install and tighten process connectors before applying pressure.
Electrical shocks
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals.High voltage that my be present on leads can
cause electrical shock.
53
Hardware InstallationReference Manual
June 202100809-0100-4801
WARNING
Replacement equipment or spare parts not approved by Emerson for use as spare
parts could reduce the pressure retaining capabilities of the transmitter and may
render the instrument dangerous.
Use only bolts supplied or sold by Emerson as spare parts.
Improper assembly of manifolds
Improper assembly of manifolds to traditional flange can damage the SuperModule
Platform.
For safe assembly of manifold to traditional flange, bolts must break black plane of flange
web (i.e., bolt hole) but must not contact module housing.
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or unintentional and
needs to be protected against.
™
Physical security is an important part of any security program and fundamental to
protecting your system. Restrict physical access by unauthorized personnel to protect end
users’ assets. This is true for all systems used within the facility.
3.3Considerations
3.3.1Installation considerations
Measurement performance depends upon proper installation of the transmitter and
impulse piping. Mount the transmitter close to the process and use minimum piping to
achieve best performance. Also, consider the need for easy access, personnel safety,
practical field calibration, and a suitable transmitter environment. Install the transmitter
to minimize vibration, shock, and temperature fluctuation.
Important
Install the enclosed pipe plug (found in the box) in the unused conduit opening. For
straight threads, a minimum of six threads must be engaged. For tapered threads, install
the plug wrench-tight. For material compatibility considerations, see Rosemount Material
Selection Technical Note.
3.3.2
Environmental considerations
Best practice is to mount the transmitter in an environment that has minimal ambient
temperature change. The transmitter electronics temperature operating limits are –40 to
185 °F (–40 to 85 °C). Refer to Rosemount 3051S Series of Instrumentation Product Data
Sheet, which lists the sensing element operating limits. Mount the transmitter so that it is
not susceptible to vibration and mechanical shock and does not have external contact with
corrosive materials.

3.3.3Mechanical considerations
Access requirements and cover installation can help optimize transmitter performance.
See the Rosemount 3051S Series of Instrumentation Product Data Sheet for temperature
operating limits.
Be sure the transmitter is securely mounted. Tilting of the transmitter may cause a zero
shift in the transmitter output.
Side mounted
When the transmitter is mounted on its side, position the coplanar flange to ensure proper
venting or draining. Mount the flange as shown in Figure 3-1, and Figure 3-2 keeping
drain/vent connections on the bottom for gas service and on the top for liquid service.

3.3.4
Draft range
Installation
For the Rosemount 3051S_CD0 Draft Range Pressure Transmitter, it is best to mount the
transmitter with the isolators parallel to the ground. Installing the transmitter in this way
reduces oil mounting effect and provides for optimal temperature performance.
Reducing process noise
There are two recommended methods of reducing process noise:
• Output damping
• Reference side filtering (in gage applications)
Reference side filtering
In gage applications it is important to minimize fluctuations in atmospheric pressure to
which the low side isolator is exposed. One method of reducing fluctuations in
atmospheric pressure is to attach a length of tubing to the reference side of the
transmitter to act as a pressure buffer.
Another method is to plumb the reference side to a chamber that has a small vent to
atmosphere. If multiple draft transmitters are being used in an application, the reference
side of each device can be plumbed to a chamber to achieve a common gage reference.
3.4Installation procedures
An overview of the installation steps for a Rosemount 3051S Pressure Transmitter is

D. Elastomer
Whenever you remove flanges or adapters, visually inspect the PTFE O-rings.
Replace them if there are any signs of damage, such as nicks or cuts. If you replace
the O-rings, re-torque the flange bolts after installation to compensate for cold
flow. Refer to the process sensor body reassembly procedure in Reassembly
procedures.
Flange bolt installation
If the transmitter installation requires assembly of the process flanges, manifolds, or
flange adapters, follow these assembly guidelines to ensure a tight seal for optimal
performance characteristics of the transmitters. Use only bolts supplied with the
transmitter or sold by Emerson as spare parts. Figure 3-4 illustrates common transmitter
assemblies with the bolt length required for proper transmitter assembly.
The transmitter can be shipped with a coplanar flange or a traditional flange installed with
four 1.75-in. flange bolts. Stainless steel bolts supplied by Emerson are coated with a
lubricant to ease installation. Carbon steel bolts do not require lubrication. No additional
lubricant should be applied when installing either type of bolt. Bolts supplied by Emerson
are identified by their head markings:

Liquid
measurement
1. Place taps to the side of the line to prevent sediment deposits
on the transmitter’s process isolators.
2. Mount the transmitter beside or below the taps so gases can
vent into the process line.
3. Mount drain/vent valve upward to allow gases to vent.
Gas
measurement
1. Place taps in the top or side of the line.
2. Mount the transmitter beside or above the taps so liquid will
drain into the process line.
Steam
measurement
1. Place taps to the side of the line.
2. Mount the transmitter below the taps to ensure that the
impulse piping will stay filled with condensate.
3. In steam service above 250 °F (121 °C), fill impulse lines with
water to prevent steam from contacting the transmitter
directly and to ensure accurate measurement start-up.
Steam service
For steam service or for applications with process temperatures greater than the limits of
the transmitter, do not blow down impulse piping through the transmitter. Flush lines
with the blocking valves closed and refill lines with water before resuming measurement.
Refer to Figure 3-1 for correct mounting orientation.
Note
For steam or other elevated temperature services, it is important that temperatures at the
process connection do not exceed the transmitter’s process temperature limits.
Best practices
The piping between the process and the transmitter must accurately transfer the pressure
to obtain accurate measurements. These are some possible sources of error: pressure
transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line,
liquid in a gas line, density variations between the legs, and plugged impulse piping.
The best location for the transmitter in relation to the process pipe is dependent on the
process. Use the following guidelines to determine transmitter location and placement of
impulse piping:
• Keep impulse piping as short as possible.
• For liquid service, slope the impulse piping at least 1 in./ft (8 cm/m) upward from the
transmitter toward the process connection.
• For gas service, slope the impulse piping at least 1 in./ft (8 cm/m) downward from the
transmitter toward the process connection.
• Avoid high points in liquid lines and low points in gas lines.
• Make sure both impulse legs are the same temperature.
• Use impulse piping large enough to avoid friction effects and blockage.
• Vent all gas from liquid piping legs.
63
Hardware InstallationReference Manual
June 202100809-0100-4801
• When using a sealing fluid, fill both piping legs to the same level.
• When purging, make the purge connection close to the process taps and purge
through equal lengths of the same size pipe. Avoid purging through the transmitter.
• Keep corrosive or hot (above 250 °F [121 °C]) process material out of direct contact
with the sensor module and flanges.
• Prevent sediment deposits in the impulse piping.
• Maintain equal leg of head pressure on both legs of the impulse piping.
• Avoid conditions that might allow process fluid to freeze within the process flange.

3.6Wiring the device
Remove orange conduit plugs
Use a conduit plug in the unused conduit opening. Thread sealing (PTFE) tape or paste on
male threads of conduit is required to provide a water/dust tight conduit seal and meets
requirements of NEMA® Type 4X, IP66, and IP68. Consult factory if other Ingress
Protection ratings are required.
74Emerson.com/RosemountEmerson.com/Rosemount
Reference ManualHardware Installation
00809-0100-4801June 2021
For M20 threads, install conduit plugs to full thread engagement or until mechanical
resistance is met.
Remove orange plugs from the transmitter conduit openings. The orange plugs are used
to keep the housing free of debris during shipping. They are not meant to be in the
conduit openings when the transmitter is installed and in use.
Install pipe plug in unused conduit opening
Important
Install the enclosed pipe plug (found in the box) in the unused conduit opening.
• For straight threads, a minimum of six threads must be engaged.
• For tapered threads, install the plug wrench-tight.
For material compatibility considerations, refer to Material Selection Technical Note.
3.6.1
Wire the device
Use twisted pairs to yield best results. To ensure proper communication, use 24 to 14
AWG wire, and do not exceed 5000 ft. (1500 m).
Note
Determine local wiring and conduit requirements. Understand local wiring and conduit
requirements prior to installation and be sure to follow all regulations during the
transmitter’s installation.

Hardware InstallationReference Manual
June 202100809-0100-4801
connect powered signal wiring to the test terminals. Power could damage the test
diode.
3. Ensure full contact with Terminal Block screw and washer. When using a direct
wiring method, wrap wire clockwise to ensure it is in place when tightening the
terminal block screw.
Note
The use of a pin or ferrule wire terminal is not recommended as the connection may
be more susceptible to loosening over time or under vibration.
4. Plug and seal the unused conduit connection on the transmitter housing to avoid
moisture accumulation in the terminal side. Install wiring with a drip loop. Arrange
the drip loop so the bottom is lower than the conduit connections and the
transmitter housing.
Surges or transients
The transmitter will withstand electrical transients of the energy level usually encountered
in static discharges or induced switching transients. However, high-energy transients,
such as those induced in wiring from nearby lightning strikes, can damage the transmitter.
Optional transient protection terminal block
The transient protection terminal block can be ordered as an installed option (Option
Code T1 in the transmitter model number) or as a spare part to retrofit existing
Rosemount 3051S Transmitters in the field. For a complete listing of spare part numbers
for transient protection terminal blocks, refer to Table 4-2. A lightning bolt symbol on a
terminal block identifies it as having transient protection.
Signal wiring grounding
Do not run signal wiring in conduit or open trays with power wiring, or near heavy
electrical equipment. Grounding terminations are provided on the sensor module and
inside the terminal compartment. These grounds are used when transient protect
terminal blocks are installed or to fulfill local regulations. See below for more information
on how the cable shield should be grounded.
Procedure
1. Remove the field terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 3-xx.
a) The terminals are not polarity sensitive.
b) The cable shield should:
• Be trimmed close and insulated from touching the transmitter housing
• Continuously connect to the termination point
• Be connected to a good earth ground at the power supply end

3. Replace the housing cover. It is recommended that the cover be tightened until
there is no gap between the cover and the housing.
4. Plug and seal unused conduit connections.
Note
A minimum loop resistance of 250 ohms is required to communicate with a Field
Communicator. If a single power supply is used to power more than one
Rosemount 3051S Transmitter, the power supply used, and circuitry common to
the transmitters, should not have more than 20 ohms of impedance at 1200 Hz.
Electrical considerations
Proper electrical installation is necessary to prevent errors due to improper grounding and
electrical noise. For Junction Box housing, shielded signal wiring should be used in high
EMI/RFI environments.
Note
Verify transmitter zero point after installation. To reset zero point, refer to Sensor trim
overview.
Cover installation
Always ensure a proper seal by installing the electronics housing cover(s) so that metal
contacts metal. Use Rosemount O-rings.

4Operation and maintenance
overview
This section contains information on commissioning and operating Rosemount™ 3051S
Pressure Transmitters. Tasks that should be performed on the bench prior to installation
are explained in this section.
Field Communicator and AMS Device Manager instructions are given to perform
configuration functions. For convenience, Field Communicator Fast Key sequences are
labeled Fast Keys for each software function below the appropriate headings.
4.1Calibration for HART® Protocol
Calibrating a Rosemount 3051S Transmitter may include the following procedures:
• Rerange: Sets the 4 and 20 mA points at required pressures.
• Sensor trim: Adjusts the position of the factory sensor characterization curve to
optimize performance over a specified pressure range, or to adjust for mounting
effects.
• Analog output trim: Adjusts the analog output to match the plant standard or the
control loop.
The Rosemount 3051S SuperModule™ uses a microprocessor that contains information
about the sensor’s specific characteristics in response to pressure and temperature inputs.
A smart transmitter compensates for these sensor variations. The process of generating
the sensor performance profile is called factory sensor characterization. Factory sensor
characterization also provides the ability to readjust the 4 and 20 mA points without
applying pressure to the transmitter.
Trim and rerange functions also differ. Reranging sets analog output to the selected upper
and lower range points and can be done with or without an applied pressure. Reranging
does not change the factory sensor characterization curve stored in the microprocessor.
Sensor trimming requires an accurate pressure input and adds additional compensation
that adjusts the position of the factory sensor characterization curve to optimize
performance over a specific pressure range.
Note
Sensor trimming adjusts the position of the factory sensor characterization curve. It is
possible to degrade performance of the transmitter if the trim is done improperly or with
inaccurate equipment.

used in differential pressure applications under high static line pressure (see ). Rosemount
3051S_TG Range 5 Transmitters use an absolute sensor that requires an accurate absolute
pressure source to perform the optional sensor trim.

Data flow
Not all calibration procedures should be performed for each transmitter. Some procedures
are appropriate for bench calibration, but should not be performed during field
calibration. Table 4-1 identifies the recommended calibration procedures for each type of
transmitter for bench or field calibration. Data flow can be summarized in four major
steps:
1. A change in pressure is measured by a change in the sensor output (sensor signal).
4.1.2
2. The sensor signal is converted to a digital format that is understood by the
microprocessor (Analog-to-Digital signal conversion).
3. Corrections are performed in the microprocessor to obtain a digital representation
of the process input (Digital PV).
4. The Digital PV is converted to an analog value (Digital-to-Analog signal conversion).

Sensor trim overview
Trim the sensor using either sensor or zero trim functions. Trim functions vary in
complexity and are application-dependent. Both trim functions alter the transmitter’s
interpretation of the input signal.
Zero trim is a single-point offset adjustment. It is useful for compensating for mounting
position effects and is most effective when performed with the transmitter installed in its
final mounting position. Since this correction maintains the slope of the characterization
curve, it should not be used in place of a sensor trim over the full sensor range.
When performing a zero trim with a manifold, refer to Manifold operation on page xx .
Note
Do not perform a zero trim on Rosemount 3051S Absolute Pressure Transmitters. Zero
trim is zero based, and absolute pressure transmitters reference absolute zero. To correct
mounting position effects on an absolute pressure transmitter, perform a low trim within
the sensor trim function. The low trim function provides an offset correction similar to the
zero trim function, but it does not require zero-based input.
Sensor trim is a 2-point sensor calibration where two end-point pressures are applied, and
all output is linearized between them. Always adjust the low trim value first to establish
the correct offset. Adjustment of the high trim value provides a slope correction to the
characterization curve based on the low trim value. The trim values allow you to optimize
performance over your specified measuring range at the calibration temperature.

Classic:± 0.1% of the upper range limit plus an additional ± 0.1% of upper range limit error for
each 1000 psi (69 bar) of line pressure above 2000 psi (138 bar).
Example: Line pressure is 3000 psi (207 bar) for Ultra performance transmitter. Zero effect
error calculation:
± {0.05 + 0.1 x [3 – 2 kpsi]} = ± 0.15% of the upper range limit
Span effect
Refer to Rosemount 3051S Product Data Sheet.
4.1.13Compensating for line pressure (Range 4 and 5)
The Rosemount 3051S Range 4 and 5 Pressure Transmitters require a special calibration
procedure when used in differential pressure applications. The purpose of this procedure is
to optimize transmitter performance by reducing the effect of static line pressure in these
applications. The Rosemount 3051S Differential Pressure Transmitters (Ranges 0, 1, 2, and
3) do not require this procedure because optimization occurs in the sensor.
Applying high static pressure to the Rosemount 3051S Range 4 and 5 Pressure
Transmitters causes a systematic shift in the output. This shift is linear with static pressure;
correct it by performing the Sensor trim procedure.
The following specifications show the static pressure effect for the Rosemount 3051S
Range 4 and 5 Transmitters used in differential pressure applications:
Zero effect
±0.1% of the upper range limit per 1000 psi (69 bar) for line pressures from 0 to 2000 psi (0
to 138 bar)
For line pressures above 2000 psi (138 bar), the zero effect error is ±0.2% of the upper
range limit plus an additional ±0.2% of upper range limit error for each 1000 psi (69 bar) of
line pressure above 2000 psi (138 bar).
Example: Line pressure is 3000 psi (207 bar). Zero effect error calculation:
± {0.2 + 0.2 x [3 kpsi – 2 kpsi]} = ±0.4% of the upper range limit
Span effect
Correctable to ±0.2% of reading per 1000 psi (69 bar) for line pressures from 0 to 3626 psi
(0 to 250 bar)
The systematic span shift caused by the application of static line pressure is –0.85% of
reading per 1000 psi (69 bar) for Range 4 transmitters, and –0.95% of reading per 1000 psi
(69 bar) for Range 5 transmitters.
Use the following example to compute corrected input values.
Example
A transmitter with model number 3051S_CD4 will be used in a differential
pressure application where the static line pressure is 1200 psi (83 bar). The
transmitter output is ranged with 4 mA at 500 inH2O (1.2 bar) and 20 mA at
1500 inH2O (3.7 bar).

Operation and maintenance overviewReference Manual
June 202100809-0100-4801
To correct for systematic error caused by high static line pressure, first use the
following formulas to determine corrected values for the low trim and high
trim.
LT = LRV + S x (LRV)
x P
HT = URV + S x
(URV) x P
Where:LT =Corrected low trim value
LRV =Lower range value
S =–(Span shift per specification)
P =Static line pressure
Where:HT =Corrected high trim value
URV =Upper range value
S =–(Span shift per specification)
P =Static line pressure
In this example:
URV =1500 inH2O (3.74 bar)
LRV =500 inH2O (1.25 bar)
P =1200 psi (82.74 bar)
S =± 0.01/1000
To calculate the low trim (LT) value:
LT =506 inH2O (1.26 bar)
LT =500 + (0.01/1000)(500)(1200)
To calculate the high trim (HT) value:
HT =1518 inH2O (3.78 bar)
HT =1500 + (0.01/1000)(1500)(1200)
Complete a sensor trim and enter the corrected values for low trim (LT) and high trim (HT),
refer to .
Enter the corrected input values for low trim and high trim through the Field
Communicator keypad after you apply the value of pressure as the transmitter input.
Note
After sensor trimming Rosemount 3051S Range 4 and 5 Transmitters for high differential
pressure applications, verify the 4 and 20 mA points are at the correct values using the
Field Communicator. For the example above, this would be 500 and 1500 respectively.
The zero effect can be eliminated by doing a zero sensor trim at line pressure after
installation without affecting the completed calibration.

4.1.14Diagnostic messages
In addition to output, the LCD displays abbreviated operation, error, and warning
messages for troubleshooting. Messages appear according to their priority; normal
operating messages appear last. To determine the cause of a message, use a Field
Communicator or AMS Device Manager to further interrogate the transmitter. A
description of each LCD display diagnostic message follows.
Error indicator
An error indicator message appears on the LCD display to warn of serious problems
affecting the operation of the transmitter. The meter displays an error message until the
error condition is corrected, ERROR appears at the bottom of the display, and analog
output is driven to the specified alarm level. No other transmitter information is displayed
during an alarm condition.
Fail Module
The SuperModule™ is malfunctioning. Possible sources of problems include:
• Pressure or temperature updates are not being received in the SuperModule.
• A non-volatile memory fault that will affect transmitter operation has been detected in
the module by the memory verification routine.
• Some non-volatile memory faults are user-repairable. Use a Field Communicator or
AMS Device Manager to diagnose the error and determine if it is repairable. Any error
message that ends in “Factory” is not repairable. In cases of non-user-repairable errors,
replace the SuperModule. See Disassembly procedures on page xx.
Fail configuration
A memory fault has been detected in a location that could affect transmitter operation,
and is user-accessible. To correct this problem, use a Field Communicator or AMS Device
Manager to interrogate and reconfigure the appropriate portion of the transmitter
memory.
Warnings
Warnings appear on the LCD display to alert you of user-repairable problems with the
transmitter, or current transmitter operations. Warnings appear alternately with other
transmitter information until the warning condition is corrected or the transmitter
completes the operation that warrants the warning message.
LCD update error
A communications error has occurred between the LCD display and the SuperModule.
Verify the LCD display is firmly seated by squeezing the two tabs, pulling the LCD display
out, making sure the pins are in the feature board and snapping the LCD display aback into
place. If this does not clear the error, replace the LCD display.
PV limit
The primary variable read by the transmitter is outside of the transmitter’s range.
Non PV limit
A non-primary variable read by the transmitter is outside of the transmitter’s range.

Operation and maintenance overviewReference Manual
June 202100809-0100-4801
Curr sat
The primary variable read by the module is outside of the specified range, and the analog
output has been driven to saturation levels.
XMRT info
A non-volatile memory fault has been detected in the transmitter memory by the memory
verification routine. The memory fault is in a location containing transmitter information.
To correct this problem, use a Field Communicator or AMS Device Manager to interrogate
and reconfigure the appropriate portion of the transmitter memory. This warning does
not affect the transmitter operation.
Press alert
A HART alert when the pressure variable read by the transmitter is outside of the user set
alert limits.
Temp alert
A HART alert when the sensor temperature variable read by the transmitter is outside of
the user set alert limits.
Operation
Normal operation messages appear on the LCD display to confirm actions or inform you of
transmitter status. Operation messages are displayed with other transmitter information
and warrant no action to correct or alter the transmitter settings.
Loop test
A loop test is in progress. During a loop test or 4–20 mA trim, the analog output is set to a
fixed value. The meter display alternates between the current selected in milliamps and
“LOOP TEST.”
The zero value, set with the local zero adjustment button, has been accepted by the
transmitter, and the output should change to 4 mA.
The zero value, set with the local zero adjustment button, exceeds the maximum
rangedown allowed for a particular range, or the pressure sensed by the transmitter
exceeds the sensor limits.
The span value, set with the local span adjustment button, has been accepted by the
transmitter, and the output should change to 20 mA.
The span value, set with the local span adjustment button, exceeds the maximum
rangedown allowed for a particular range, or the pressure sensed by the transmitter
exceeds the sensor limits.
This message appears during reranging with the integral zero and span buttons and
indicates that the transmitter local zero and span adjustments have been disabled. The
adjustments have been disabled by software commands from the Field Communicator or
AMS Device Manager. Keys are disabled when write protect jumper is “ON.” If alarm and
security adjustments are not installed, the transmitter will operate normally with the
default alarm condition alarm high and the security off.
Stuck key
The zero or span button is stuck in the depressed state or pushed too long.
