TRANSMITTER
OVERVIEW
00809-0300-4101, Rev AA
April 2011
The Rosemount 2051C Coplanar™ design is offered for Differential Pressure
(DP), Gage Pressure (GP) and Absolute Pressure (AP) measurements. The
Rosemount 2051C utilizes Emerson Process Management capacitance
sensor technology for DP and GP measurements. Piezoresistive sensor
technology is utilized in the Rosemount 2051T.
The major components of the Rosemount 2051 are the sensor module and
the electronics housing. The sensor module contains the oil filled sensor
system (isolating diaphragms, oil fill system, and sensor) and the sensor
electronics. The sensor electronics are installed within the sensor module and
include a temperature sensor (RTD), a memory module, and the capacitance
to digital signal converter (C/D converter). The electrical signals from the
sensor module are transmitted to the output electronics in the electronics
housing. The electronics housing contains the output electronics board, the
optional local operator interface (LOI) buttons, and the terminal block.
For the Rosemount 2051C design pressure is applied to the isolating
diaphragms, the oil deflects the center diaphragm, which then changes the
capacitance. This capacitance signal is then changed to a digital signal in the
C/D converter. The microprocessor then takes the signals from the RTD and
C/D converter calculates the correct output of the transmitter.

CONFIGURATION
GUIDELINES
00809-0300-4101, Rev AA
April 2011
The Rosemount 2051 can be configured either before or after installation.
Configuring the transmitter on the bench using the Local Operator Interface
(LOI) or class two master ensures that all transmitter components are in
working order prior to installation.
To configure on the bench, required equipment includes a power supply, an
LOI (option M4) or a class two master with DP/PA coupler, proper cable and
terminators.
Verify that the Security hardware jumper is set to the OFF position in order to
proceed with configuration. See Figure 4-2 for jumper location.
Profile 3.02 Identification
Number Adaptation
Mode
Rosemount 2051 PROFIBUS Profile 3.02 devices are set to Identification
Number Adaptation mode (0127) when shipped from the factory. This mode
allows the transmitter to communicate with any PROFIBUS class one master
with either the generic Profile GSD (9700) or Rosemount 2051 specific GSD
(3333).
Block Modes
When configuring a device with the LOI, the output status will change to Good
– Function Check to alert hosts that the transmitter is not in standard
operation mode.
When configuring a device with a class two master, blocks must be set to
Out of Service (OOS) in order to download parameters that could affect the
output. This prevents the class one master from seeing a jump in output
without a status change. Setting the blocks OOS and back into Auto is done
automatically using the class two master when using the Rosemount 2051 DD
or DTM, so no additional action is required when configuring the device.
Configuration Tools
The Rosemount 2051 can be configured using two tools: LOI or class two
master.
The LOI requires option code M4 to be ordered. To activate the LOI, push
either configuration button located under the top tag of the transmitter. See
Table 2-1 and Figure 2-1 for operation and menu information. See Appendix
D for a complete LOI menu tree.
Class two masters require either DD or DTM files for configuration. These
files can be found at www.rosemount.com or by contacting your local
Emerson Process representative.
The remainder of this section will cover the configuration tasks using either
configuration tool.
NOTE
Instructions in this section use the language found in the class two master or
LOI. See Appendix D: Profibus Block Information to cross reference
parameters between the class two master, LOI and PROFIBUS specification.

The Rosemount 2051 has a hierarchy of security features. The security
jumper on the electronics board (or optional LCD display) provides the highest
level of security. With the jumper in the ON position, all writes to the
transmitter will be disabled (including writes from the LOI or a class two
master).
See Section 4: Configure Security and Simulation for details on jumper
configuration.
LOI Security
In addition to the security jumper, the Rosemount 2051 PROFIBUS LOI can
be protected using two different software parameters:
•
LOI Enable: Prevents operation of the local configuration buttons,
hence disabling the LOI.
•
LOI Password: Requires a user to enter a non-zero four digit password
at the transmitter in order to operate the LOI.
These parameters can be set using,

NOTE
Security jumper must be in the off position and the buttons must be enabled
for the LOI to operate. The Password appears after the LOI is activated using
the local configuration buttons.
Simulation
Simulation is in the AI block and used to verify the output from the transducer
block. The Rosemount 2051 has a simulation jumper located on the
electronics board (or optional LCD display) that must be set to the ON position
in order to simulate.
NOTE
This jumper position is ignored when the transmitter is initially powered. The
jumper position must be changed while the transmitter is powered to activate
simulation. If power is removed and restored, the simulation mode will be OFF
regardless of jumper position.
With simulation enabled, the actual measurement value has no impact on the
OUT value or the status. The OUT value will equal the simulated value from
the transducer block plus any scaling or linearization effects performed in the
AI block.
Once the simulation jumper is set to on, simulation mode can be activated

Rosemount 2051
INSTALLATION
CONSIDERATIONS
Measurement accuracy depends upon proper installation of the transmitter
and impulse piping. Mount the transmitter close to the process and use a
minimum of piping to achieve best accuracy. Keep in mind 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 unused conduit opening.
Engage a minimum of five threads to comply with explosion-proof
requirements. See Conduit Entry Threads for additional requirements. For
NEMA 4X, IP66, and IP68 requirements, use thread seal (PTFE) tape or
paste on male threads to provide a watertight seal.
For material compatibility considerations, see document number
00816-0100-3045 on www.emersonprocess.com/rosemount.
Mechanical
Considerations
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.
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 3-9 on
page 3-8, keeping drain/vent connections on the bottom for gas service and
on the top for liquid service.
Environmental
Considerations
3-2
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 Appendix A:
Specifications and Reference Data that 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.
Reference Manual
00809-0300-4101, Rev AA
April 2011
Rosemount 2051
INSTALLATION
PROCEDURES
Mount the Transmitter
For dimensional drawing information refer to Appendix A: Specifications and
Reference Data on page A-13.
Process Flange Orientation
Mount the process flanges with sufficient clearance for process connections.
For safety reasons, place the drain/vent valves so the process fluid is directed
away from possible human contact when the vents are used. In addition,
consider the need for a testing or calibration input.
Housing Rotation
The electronics housing can be rotated up to 180 degrees in either direction to
improve field access, or to better view the optional LCD display. To rotate the
housing, perform the following procedure:
51. Loosen the housing rotation set screw using a -----in. hex wrench.
64
2. Turn the housing left or right up to 180° from its original position. Over
rotating will damage the transmitter.
3. Retighten the housing rotation set screw.
Figure 3-1. Housing Rotation
Housing Rotation Set
Screw (5/64-in.)
Terminal Side of Electronics Housing
Mount the transmitter so the terminal side is accessible. Clearance of 0.75 in.
(19 mm) is required for cover removal. Use a conduit plug in the unused
conduit opening.
Circuit Side of Electronics Housing
Provide 0.75 in. (19 mm) of clearance for units with out an LCD display. If LCD
display is installed, mount for clear visibility. Three inches of clearance is
required for LCD display cover removal.
Conduit Entry Threads
For NEMA 4X, IP66, and IP68 requirements, use thread seal (PTFE) tape or
paste on male threads to provide a watertight seal.

Impulse Piping
Mounting Requirements
Impulse piping configurations depend on specific measurement conditions.
Refer to Figure 3-9 for examples of the following mounting configurations:
Liquid Flow Measurement
•
Place taps to the side of the line to prevent sediment deposits on the
transmitter’s process isolators.
•
Mount the transmitter beside or below the taps so gases can vent into
the process line.
•
Mount drain/vent valve upward to allow gases to vent.
Gas Flow Measurement
•
Place taps in the top or side of the line.
•
Mount the transmitter beside or above the taps so liquid will drain into
the process line.
Steam Flow Measurement
•
Place taps to the side of the line.
•
Mount the transmitter below the taps to ensure that the impulse piping
will stay filled with condensate.
•
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.
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. There are five 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, and density variations
between the legs.
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./foot (8 cm/m)
upward from the transmitter toward the process connection.
•
For gas service, slope the impulse piping at least 1 in./foot (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.
•
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.

Process Connections
Coplanar or Traditional Process Connection
Install and tighten all four flange bolts before applying pressure, or process
leakage will result. When properly installed, the flange bolts will protrude
through the top of the sensor module housing. Do not attempt to loosen or
remove the flange bolts while the transmitter is in service.
Flange Adaptors:
Rosemount 2051DP and GP process connections on the transmitter flanges
are 1/4–18 NPT. Flange adapters are available with standard 1/2–14 NPT class
2 connections. The flange adapters allow users to disconnect from the
process by removing the flange adapter bolts. Use plant-approved lubricant or
sealant when making the process connections. Refer to Dimensional
Drawings on page A-13 for the distance between pressure connections. This
distance may be varied ±1/8 in. (3.2 mm) by rotating one or both of the flange
adapters.
To install adapters to a Coplanar flange, perform the following procedure:
1.
Remove the flange bolts.
2.
Leaving the flange in place, move the adapters into position with the
o-ring installed.
3.
Clamp the adapters and the Coplanar flange to the transmitter sensor
module using the larger of the bolts supplied.
4.
Tighten the bolts. Refer to “Flange Bolts” on page 3-6 for torque
specifications.
Whenever you remove flanges or adapters, visually inspect the PTFE o-rings.
Replace with o-ring designed for Rosemount transmitter if there are any signs
of damage, such as nicks or cuts. Undamaged o-rings may be reused. If you
replace the o-rings, retorque the flange bolts after installation to compensate
for cold flow. Refer to the process sensor body reassembly procedure in
Section 5: Troubleshooting.
When compressed, PTFE O-rings tend to “cold flow,” which aids in their
sealing capabilities.
NOTE
PTFE O-rings should be replaced if the flange adapter is removed.

O-rings:
The two styles of Rosemount flange adapters (Rosemount 1151 and
Rosemount 2051S/2051/2051/3095) each require a unique O-ring (see
Figure 3-10). Use only the O-ring designed for the corresponding flange
adaptor.
Figure 3-10. O-Rings.
Failure to install proper flange adapter O-rings may cause process leaks, which can result in death
or serious injury. The two flange adapters are distinguished by unique O-ring grooves. Only use
the O-ring that is designed for its specific flange adapter, as shown below.

Manifold Installation
Procedure
Rosemount 2051
To install a 305 Integral Manifold to a 2051 transmitter:
1. Inspect the PTFE sensor module o-rings. Undamaged o-rings may be
reused. If the o-rings are damaged (if they have nicks or cuts, for
example), replace with o-rings designed for Rosemount transmitter.
IMPORTANT
If replacing the o-rings, take care not to scratch or deface the o-ring grooves
or the surface of the isolating diaphragm while you remove the damaged
o-rings.
2. Install the Integral Manifold on the sensor module. Use the four 2.25-in.
manifold bolts for alignment. Finger tighten the bolts, then tighten the
bolts incrementally in a cross pattern to final torque value. See “Flange
Bolts” on page 3-6 for complete bolt installation information and torque
values. When fully tightened, the bolts should extend through the top of
the sensor module housing.
3. If the PTFE sensor module o-rings have been replaced, the flange bolts
should be re-tightened after installation to compensate for cold flow of
the o-rings.
NOTE
Always perform a zero trim on the transmitter/manifold assembly after
installation to eliminate mounting effects.

LIQUID LEVEL
MEASUREMENT
Differential pressure transmitters used for liquid level applications measure
hydrostatic pressure head. Liquid level and specific gravity of a liquid are
factors in determining pressure head. This pressure is equal to the liquid
height above the tap multiplied by the specific gravity of the liquid. Pressure
head is independent of volume or vessel shape.
Open Vessels
A pressure transmitter mounted near a tank bottom measures the pressure of
the liquid above.
Make a connection to the high pressure side of the transmitter, and vent the
low pressure side to the atmosphere. Pressure head equals the liquid’s
specific gravity multiplied by the liquid height above the tap.
Zero range suppression is required if the transmitter lies below the zero point
of the desired level range. Figure 3-13 shows a liquid level measurement
example.
Closed Vessels
Pressure above a liquid affects the pressure measured at the bottom of a
closed vessel. The liquid specific gravity multiplied by the liquid height plus
the vessel pressure equals the pressure at the bottom of the vessel.
To measure true level, the vessel pressure must be subtracted from the
vessel bottom pressure. To do this, make a pressure tap at the top of the
vessel and connect this to the low side of the transmitter. Vessel pressure is
then equally applied to both the high and low sides of the transmitter. The
resulting differential pressure is proportional to liquid height multiplied by the
liquid specific gravity.
Dry Leg Condition
Low-side transmitter piping will remain empty if gas above the liquid does not
condense. This is a dry leg condition. Range determination calculations are
the same as those described for bottom-mounted transmitters in open
vessels, as shown in Figure 3-13.
Figure 3-13. Liquid Level
Measurement Example.

measurable levels (500 in.).

Let h equal the maximum head pressure to be measured in inches of water.
Let e equal head pressure produced by Y expressed in inches of water.

Wet Leg Condition
Condensation of the gas above the liquid slowly causes the low side of the
transmitter piping to fill with liquid. The pipe is purposely filled with a
convenient reference fluid to eliminate this potential error. This is a wet leg
condition.
The reference fluid will exert a head pressure on the low side of the
transmitter. Zero elevation of the range must then be made. See Figure 3-14

open vessels. This system consists of an air supply, pressure regulator,
constant flow meter, pressure transmitter, and a tube that extends down into
the vessel.
Bubble air through the tube at a constant flow rate. The pressure required to
maintain flow equals the liquid’s specific gravity multiplied by the vertical

Transmitters ordered with the LCD display with Local Operator Interface
option (M4) are shipped with the display and local configuration buttons
installed. The configuration buttons are located under the top tag as indicated
by the sticker. See Table 2-1 for LOI operation. Upgrading to an LOI
transmitter requires installation of a new electronics board, configuration
buttons and LCD display (if not previously ordered).
Configure Security and
Simulation
Security (Write Protect)
There are three security methods with the Rosemount 2051 transmitter:
1.
Security Jumper: prevents all writes to transmitter configuration.
2.
Local Keys Software Lock Out: prevents changes to transmitter range
points using local configuration buttons.
3.
Physical Removal of Local Buttons: removes ability to use local
buttons.
You can prevent changes to the transmitter configuration data with the write
protection jumper. Security is controlled by the security (write protect) jumper
located on the electronics board or LCD display. Position the jumper on the
transmitter circuit board in the “ON” position to prevent accidental or
deliberate change of configuration data.
If the transmitter write protection jumper is in the “ON” position, the transmitter
will not accept any “writes” to its memory.
NOTE
If the security jumper is not installed, the transmitter will continue to operate in
the security OFF configuration.
Simulate
The Rosemount 2051 has a simulate jumper located on the electronics board
(or optional LCD display) that must be set to the ON position in order to
activate simulate mode using a class two master.
See Section 2: Configuration for details on Simulate mode.

CONSIDERATIONS
Conduit Installation
Make sure all electrical installation is in accordance with national and local
code requirements.
Recommended conduit connections are shown in Figure 4-3.
If all connections are not sealed, excess moisture accumulation can damage the
transmitter. Make sure to mount the transmitter with the electrical housing positioned
downward for drainage. To avoid moisture accumulation in the housing, install wiring

Power Supply
The dc power supply should provide power with less than two percent ripple.
The transmitter requires between 9 and 32 Vdc at the terminals to operate
and provide complete functionality.
Power Conditioner
The DP/PA Coupler / Link often includes an integrated power conditioner.
Grounding
Transmitters are electrically isolated to 500 Vac rms. Signal wiring can not be
grounded.
Shield Wire Ground
Grounding techniques for shield wire usually require a single grounding point
for shield wire to avoid creating a ground loop. The ground point is typically at
the power supply.
Transient Protection
Terminal Block
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.
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 2051 transmitters in the field. See “Parts List” on page A-42 for spare
part numbers. The lightning bolt symbol shown in Figure 4-7 identifies the
transient protection terminal block.

NOTE
The transient protection terminal block does not provide transient protection
unless the transmitter case is properly grounded. Use the guidelines to
ground the transmitter case. Refer to page 4-7.
Do not run the transient protection ground wire with signal wiring as the
ground wire may carry excessive current if a lightning strike occurs.
Grounding
Use the following techniques to properly ground the transmitter signal wiring
and case:
Signal Wiring
Do not run signal wiring in conduit or open trays with power wiring or near
heavy electrical equipment. It is important that the instrument cable shield be:
•
Trimmed close and insulated from touching the transmitter housing
•
Connected to the next shield if cable is routed through a junction box
•
Connected to a good earth ground at the power supply end
Transmitter Case
Always ground the transmitter case in accordance with national and local
electrical codes. The most effective transmitter case grounding method is a
direct connection to earth ground with minimal impedance. Methods for
grounding the transmitter case include:
•
Internal Ground Connection: The Internal Ground Connection screw
is inside the FIELD TERMINALS side of the electronics housing. This
screw is identified by a ground symbol ( ). The ground connection
screw is standard on all Rosemount 2051 transmitters. Refer to
Figure 4-4.
•
External Ground Assembly: This assembly is included with the
optional transient protection terminal block (Option Code T1), and it is
included with various hazardous location certifications. The External
Ground Assembly can also be ordered with the transmitter (Option
Code V5), or as a spare part. See “Parts List” on page A-42. Refer to
Figure 4-8 for location of the External Ground Screw.

CALIBRATION
OVERVIEW
Calibration is defined as the process required to optimize transmitter accuracy
over a specific range by adjusting the factory sensor characterization curve
located in the microprocessor. This is done by performing one of the following
procedures,
Zero Trim
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.
When performing a zero trim with a manifold, refer to “Manifold Operation” on
page 3-15.
NOTE
Do not perform a zero trim on absolute pressure transmitters. Zero trim is zero
based, and absolute pressure transmitters reference absolute zero. To correct
mounting position effects on absolute pressure transmitters, perform a lower
trim within the sensor trim function. The lower trim function provides an offset
correction similar to the zero trim function, but it does not require zero-based
input.
Sensor Trim
A two-point sensor calibration where two end-point pressures are applied,
and all output is linearized between them. Always adjust the lower trim value
first to establish the correct offset. Adjustment of the upper trim value provides
a slope correction to the characterization curve based on the lower trim value.
The trim values allow you to optimize performance over your specified
measuring range at the calibration temperature. Sensor trimming requires an
accurate pressure input – at least 4 times more accurate than the transmitter
– in order to optimize performance over a specific pressure range.
NOTE
The Rosemount 2051 has been carefully calibrated at the factory. Trimming
adjusts the position of the factory characterization curve. It is possible to
degrade performance of the transmitter if any trim is done improperly or with
inaccurate equipment.
NOTE
Rosemount 2051C Range 4 and Range 5 transmitters require a special
calibration procedure when used in differential pressure applications under
high static line pressure. See “Compensating for Line Pressure” on page 5-7.
Recall Factory Trim
5-2
A command that allows the restoration of the as-shipped factory settings of
the sensor trim. This command can be useful for recovering from an
inadvertent zero trim of an absolute pressure unit or inaccurate pressure
source.

COMPENSATING FOR
LINE PRESSURE
Range 2 and Range 3
The following specifications show the static pressure effect for the Rosemount
2051 Range 2 and Range 3 pressure transmitters used in differential pressure
applications where line pressure exceeds 2000 psi (138 bar).
Zero Effect
± 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). Zero effect error calculation:
± {0.01 + 0.1 x [3 kpsi - 2 kpsi]} = ± 0.2% of the upper range limit
Span Effect
Refer to “Line Pressure Effect” on page A-3.
Range 4 and Range 5
Rosemount 2051 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 2051 differential
pressure transmitters (Ranges 1, 2, and 3) do not require this procedure
because optimization occurs in the sensor.
Applying high static pressure to 2051 Range 4 and Range 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 on
page 5-2.
The following specifications show the static pressure effect for 2051 Range 4
and Range 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 (3 kpsi). 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 -1.00% of reading per 1000 psi (69 bar) for Range 4 transmitters, and
-1.25% of reading per 1000 psi (69 bar) for Range 5 transmitters.

ACTION
The Rosemount 2051 PROFIBUS device diagnostics can be used to warn a
user about a potential transmitter error. There is a transmitter error if the
Output Status reads anything but Good or Good - Function Check, or the LCD
reads SNSR or ELECT. Use Table 6-1 to identify what Diagnostic Condition
exists based on the combination of errors under the How to Identify columns.
Start with the Physical Block Diagnostic Extension and use Primary Value and
Temperature status to identify Diagnostic Condition. If a box is blank, it is not

PROCEDURES
Do not remove the instrument cover in explosive atmospheres when the
circuit is live.
Remove from Service
Follow these steps:
Remove Terminal Block
•
Follow all plant safety rules and procedures.
•
Isolate and vent the process from the transmitter before removing the
transmitter from service.
•
Remove all electrical leads and disconnect conduit.
•
Remove the transmitter from the process connection.
•
The Rosemount 2051C transmitter is attached to the process

single hex nut process connection. Loosen the hex nut to
separate the transmitter from the process. Do not wrench on neck
of transmitter.
•
Do not scratch, puncture, or depress the isolating diaphragms.
•
Clean isolating diaphragms with a soft rag and a mild cleaning solution,
and rinse with clear water.
•
For the 2051C, whenever you remove the process flange or flange
adapters, visually inspect the PTFE o-rings. Replace the o-rings if they
show any signs of damage, such as nicks or cuts. Undamaged o-rings
may be reused.
Electrical connections are located on the terminal block in the compartment
labeled “FIELD TERMINALS.”
1. Remove the housing cover from the field terminal side.
2. Loosen the two small screws located on the assembly in the 9 o’clock
and 5 o’clock positions.
3. Pull the entire terminal block out to remove it.
See “Safety Messages” on page 6-1 for complete warning information.

Remove the
Electronics Board
Rosemount 2051
The transmitter electronics board is located in the compartment opposite the
terminal side. To remove the electronics board perform the following
procedure:
1. Remove the housing cover opposite the field terminal side.
2. If you are disassembling a transmitter with a LCD display, loosen the two
captive screws that are visible on the right and left side of the meter
display.
3. Loosen the two captive screws that anchor the board to the housing. The
electronics board is electrostatically sensitive; observe handling
precautions for static-sensitive components. Use caution when removing
the LCD as there is an electronic pin connector that interfaces between
the LCD and electronics board. The two screws anchor the LCD display
to the electronics board and the electronics board to the housing.
4. Using the two captive screws, slowly pull the electronics board out of the
housing. The sensor module ribbon cable holds the electronics board to
the housing. Disengage the ribbon cable by pushing the connector
release.
Remove the Sensor
Module from the
Electronics Housing
1. Remove the electronics board. Refer to ”Remove the Electronics Board”.
IMPORTANT
To prevent damage to the sensor module ribbon cable, disconnect it from the
electronics board before you remove the sensor module from the electrical
housing.
2. Carefully tuck the cable connector completely inside of the internal black
cap.
NOTE
Do not remove the housing until after you tuck the cable connector completely
inside of the internal black cap. The black cap protects the ribbon cable from
damage that can occur when you rotate the housing.
3. Loosen the housing rotation set screw with a 5/64-inch hex wrench, and
loosen one full turn.
4. Unscrew the module from the housing, making sure the black cap and
sensor cable do not catch on the housing.

REASSEMBLY
PROCEDURES
1. Inspect all cover and housing (non-process wetted) O-rings and replace
if necessary. Lightly grease with silicone lubricant to ensure a good seal.
2. Carefully tuck the cable connector completely inside the internal black
cap. To do so, turn the black cap and cable counterclockwise one
rotation to tighten the cable.
3. Lower the electronics housing onto the module. Guide the internal black
cap and cable through the housing and into the external black cap.
4. Turn the module clockwise into the housing.
IMPORTANT
Make sure the sensor ribbon cable and internal black cap remain completely
free of the housing as you rotate it. Damage can occur to the cable if the
internal black cap and ribbon cable become hung up and rotate with the
housing.
5. Thread the housing completely onto the sensor module. The housing
must be no more than one full turn from flush with the sensor module to
comply with explosion proof requirements.
6. Tighten the housing rotation set screw using a 5/64-inch hex wrench.
Attach the
Electronics Board
1. Remove the cable connector from its position inside of the internal black
cap and attach it to the electronics board.
2. Using the two captive screws as handles, insert the electronics board
into the housing. Make sure the posts from the electronics housing
properly engage the receptacles on the electronics board. Do not force.
The electronics board should slide gently on the connections.
3. Tighten the captive mounting screws.
4. Replace the electronics housing cover. The transmitter covers must be
engaged metal-to-metal to ensure a proper seal and to meet
Explosion-Proof requirements.
Install the Terminal Block
1. Gently slide the terminal block into place, making sure the two posts from
the electronics housing properly engage the receptacles on the terminal
block.
2. Tighten the captive screws.
3. Replace the electronics housing cover. The transmitter covers must be
fully engaged to meet Explosion-Proof requirements.
See “Safety Messages” on page 6-1 for complete warning information.

Reassemble the 2051C
Process Flange
Rosemount 2051
1. Inspect the sensor module PTFE o-rings. Undamaged o-rings may be
reused. Replace o-rings that show any signs of damage, such as nicks,
cuts, or general wear.
NOTE
If you are replacing the o-rings, be careful not to scratch the o-ring grooves or
the surface of the isolating diaphragm when removing the damaged o-rings.
2.
Install the process connection. Possible options include:
a. Coplanar Process Flange:
• Hold the process flange in place by installing the two alignment screws
to finger tightness (screws are not pressure retaining). Do not
overtighten as this will affect module-to-flange alignment.
• Install the four 1.75-in. flange bolts by finger tightening them to the
flange.
b. Coplanar Process Flange with Flange Adapters:
• Hold the process flange in place by installing the two alignment screws
to finger tightness (screws are not pressure retaining). Do not
overtighten as this will affect module-to-flange alignment.
• Hold the flange adapters and adapter o-rings in place while installing the
four configurations, use four 2.88-in. bolts. For gage pressure
configurations, use two 2.88-in. bolts and two 1.75-in. bolts.
c. Manifold:
• Contact the manifold manufacturer for the appropriate bolts and
procedures.
3. Tighten the bolts to the initial torque value using a crossed pattern. See
Table 6-7 for appropriate torque values.

Failure Mode Alarm
If self-diagnostics detect a sensor or microprocessor failure, the analog signal
is driven either high or low to alert the user. High or low failure mode is
user-selectable with a jumper on the transmitter. The values to which the
transmitter drives its output in failure mode depend on whether it is
factory-configured to standard or NAMUR-compliant operation. The values for
each are as follows:
Standard Operation
Output Code
Linear Output
Fail High
Fail Low
A
M
3.9  I  20.8
0.97  V  5.2
I  21.75 mA

If self-diagnostics detect a gross transmitter failure, that information gets
passed as a status along with the process variable.
