Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Please review
the approvals section of the 2051 reference manual for any restrictions associated with a
safe installation.
Before connecting a HART-based 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.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
conditions.

This device may not cause harmful interference. This device must accept any interference
received, including interference that may cause undesired operation.
This device must be installed to ensure a minimum antenna separation distance of 8 in.
(20cm) from all persons.
Process leaks may cause harm or result in death.
To avoid process leaks, only use the o-ring designed to seal with the corresponding
flange adapter.
Electrical shock can result in death or serious injury.


Avoid contact with the leads and the terminals. High voltage that may be present on
leads can cause electrical shock.
The Rosemount 2051 and all other wireless devices should be installed only after the Smart

Shipping considerations for wireless products (Lithium Batteries: Green Power Module,
model number 701PGNKF):
The unit was shipped to you without the Power Module installed. Please remove the
Power Module from the unit prior to shipping.
Each power module contains one “D” size primary lithium-thionyl chloride battery.
Primary lithium batteries are regulated in transportation by the U.S. Department of
Transportation, and are also covered by IATA (International Air Transport Association),
ICAO (International Civil Aviation Organization), and ARD (European Ground
Transportation of Dangerous Goods). It is the responsibility of the shipper to ensure
compliance with these or any other local requirements. Please consult current
regulations and requirements before shipping.
The power module with the wireless unit contains one “D” size primary lithium-thionyl
chloride battery (Green Power Module, model number 701PGNKF). Each battery contains
approximately 5.0 grams of lithium. Under normal conditions, the battery materials are
self-contained and are not reactive as long as the battery and the pack integrity are
maintained. Care should be taken to prevent thermal, electrical or mechanical damage.
Contacts should be protected to prevent premature discharge.
Battery hazards remain when cells are discharged.
Power modules should be stored in a clean and dry area. For maximum battery life, storage
temperature should not exceed 30 °C (86 °F).
The Power Module may be replaced in a hazardous area. The Power Module has surface
resistivity greater than one gigaohm and must be properly installed in the wireless device
enclosure. Care must be taken during transportation to and from the point of installation to
prevent electrostatic charge build-up.
Using the Rosemount 2051 Wireless Pressure Transmitter in a manner other than what is
specified by the manufacturer may impair the protection provided by the equipment.

Transmitter overview
The Rosemount 2051C Coplanar design is offered for Differential Pressure (DP), Gage Pressure
(GP) and Absolute Pressure (AP) measurements. The Rosemount 2051C utilizes capacitance
sensor technology for DP and GP measurements. The Rosemount 2051T and 2051CA utilize
piezo-resistive sensor technology for AP and GP measurements.
The major components of the Rosemount 2051 Wireless transmitter 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, a memory module, and
the analog to digital signal converter (A/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 antenna, and the battery. The basic block
diagram of the Rosemount 2051CD Wireless device is illustrated in Figure 1-3 on page 5.
For the Rosemount 2051, pressure is applied to the isolating diaphragm(s). The oil deflects the
sensor which then changes its capacitance or voltage signal. This signal is then changed to a
digital signal by the Signal Processing Module. The microprocessor then takes the signals from
the Signal Processing Module and calculates the correct output of the transmitter. This signal is
then sent via wireless communication to the Gateway.
An optional LCD can be ordered that connects directly to the output electronics board which
maintains direct access to the signal terminals. The display indicates output and abbreviated
diagnostic messages. A clear display cover is provided. For WirelessHART output, the LCD
Display features a three-line display. The first line describes the process variable measured, the
second line displays the measured value, and the third line displays engineering units. The LCD
can also display diagnostics messages.
Note
LCD Display utilizes a 3-line, 7-digit character display and can display output and diagnostic
messages. See Figure 1-2.

Considerations before transmitter installation
1.5.1
Wireless considerations
Power up sequence
The Power Module should not be installed on any wireless device until the Smart Wireless
Gateway is installed and functioning properly. This transmitter uses the Green Power Module
(order model number 701PGNKF). Wireless devices should also be powered up in order of
proximity from the Smart Wireless Gateway, beginning with the closest. This will result in a
simpler and faster network installation. Enable Active Advertising on the Gateway to ensure that
new devices join the network faster. For more information, see the Smart Wireless Gateway
Manual (Doc. No. 00809-0200-4420).
Antenna position
The internal antenna is designed for multiple mounting orientations. The transmitter should be
mounted according to best practices for your pressure measurement application.

Network design best practices
When mounting the device, recommended practices should be considered to achieve the best
wireless performance. See Appendix D: Network design best practices for more information on
recommended practices.
Field communicator connections
The Power Module needs to be installed in the device for the Field Communicator to interface
with the Rosemount 2051. The Field Communicator connections are located on the Power
Module. To communicate to the transmitter, connect the Field Communicator to the COMM
port connections on the Power Module. This transmitter uses the Green Power Module; please
order model number 701PGNKF. Field communication with this device requires a HART-based
Field Communicator using the correct Rosemount 2051 Wireless DD. The Power Module is
keyed and can only be inserted in one orientation. Refer to Figure 1-4 for instructions on
connecting the Field Communicator to the 2051.
Figure 1-4. Field Communicator Connections
1.5.2
Mechanical
Location
When choosing an installation location and position, take into account access to the power
module compartment for easy power module replacement.
Electronics cover
The electronics cover is tightened so that polymer contacts polymer. When removing the
electronics cover, ensure that there is no damage done to the o-ring. If damaged replace before
reattaching cover, ensuring polymer contacts polymer (i.e. no o-ring visible).
1.5.3
Electrical
Power module
The Rosemount 2051 Wireless Pressure Transmitter is self-powered. The Power Module
contains a primary lithium-thionyl chloride battery (Green Power Module, model number
6
Introduction
Reference Manual
Section 1: Introduction

701PGNKF). Each battery contains approximately 5 grams of lithium. Under normal conditions,
the battery materials are self-contained and are not reactive as long as the battery and the
Power Module are maintained. Care should be taken to prevent thermal, electrical, or
mechanical damage. Contacts should be protected to prevent premature discharge.
Use caution when handling the Power Module, it may be damaged if dropped from heights in
excess of 6.10 m (20 ft).
1.5.4
Environmental
Verify that the operating atmosphere of the transmitter is consistent with the appropriate
hazardous locations certifications.
Temperature effects
The transmitter will operate within specifications for ambient temperatures between -40 and 85
°C (-40 and 185 °F).
Heat from the process is transferred to the transmitter housing. If the process temperature is
high, the ambient temperature will need to be lower to account for heat transferred to the
transmitter housing. See “Process Temperature Limits” on page 96 for process temperature
derating.
1.6

Set transmitter percent of range (transfer function)
The Rosemount 2051 Wireless transmitter has two transfer functions for pressure applications:
Linear and Square Root. As shown in Figure 2-2 on page 15, activating the square root options
the transmitter analog output proportional to flow.
However, for DP Flow and DP Level applications it is recommended to use Scaled Variable. Refer
to “Diagnostics and service” on page 24 for setup instructions.
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 percent to 0.8 percent, curve slope equals 42 (y = 42x) to
achieve continuous transition from linear to square root at the transition point.

2.6.1
Configuring scaled variable
The Scaled Variable configuration allows the user to create a relationship/conversion between
the pressure units and user-defined/custom units. There are two use cases for Scaled Variable.
The first use case is to allow custom units to be displayed on the transmitter's LCD Display. The
second use case is to allow custom units to drive the transmitter's PV output.
If the user desires custom units to drive the PV output, Scaled Variable must be re-mapped as
the primary variable. Refer to “Re-Mapping device variables” on page 18.
The Scaled Variable configuration defines the following items:

Scaled Variable units - Custom units to be displayed.

Scaled data options - Defines the transfer function for the application
–
Linear
–
Square root

Pressure value position 1 - Lower known value point with consideration of linear offset.

Scaled Variable value position 1 - Custom unit equivalent to the lower known value
point.

Pressure value position 2 - Upper known value point

Scaled Variable value position 2 - Custom unit equivalent to the upper known value
point

Linear offset - The value required to zero out pressures affecting the desired pressure
reading.

Low flow cutoff - Point at which output is driven to zero to prevent problems caused by
process noise. It is highly recommended to use the low flow cutoff function in order to
have a stable output and avoid problems due to process noise at a low flow or no flow
condition. A low flow cutoff value that is practical for the flow element in the
application should be entered.

Electrical shock can result in 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 Process Management 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 Process Management as spare parts.
Improper assembly of manifolds to traditional flange can damage sensor module.

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.
The Power Module with the wireless unit contains a primary lithium-thionyl chloride
battery. Each Power Module contains approximately 5.0 grams of lithium. Under normal
conditions, the Power Module materials are self-contained and are not reactive as long as
the batteries and the pack integrity are maintained. Care should be taken to prevent
thermal, electrical or mechanical damage. Contacts should be protected to prevent
premature discharge.

3.3
Considerations
3.3.1
Installation considerations
Measurement performance 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
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.
3.3.2
Wireless considerations
Power up sequence
The Power Module should not be installed on any wireless device until the Smart Wireless
Gateway is installed and functioning properly. This transmitter uses the Green Power Module
(order model number 701PGNKF). Wireless devices should also be powered up in order of
proximity from the Smart Wireless Gateway, beginning with the closest. This will result in a
simpler and faster network installation. Enable Active Advertising on the Gateway to ensure that
new devices join the network faster. For more information, see the Smart Wireless Gateway
Manual (Doc. No. 00809-0200-4420).

Section 3: Installation
Reference Manual
00809-0100-4102, Rev AA
May 2013
Internal antenna position
The internal antenna is designed for multiple mounting orientations. The transmitter should be
mounted according to measurement best practices for your pressure measurement application.
The antenna should be approximately 3 ft (1 m) from any large structure or building to allow
clear communication to other devices.
Field communicator connections
In order for the Field Communicator to interface with the Rosemount 2051 Wireless
Transmitter, the Power Module must be connected. Refer to Figure 3-1 for a diagram on how to
connect the Field Communicator.
Figure 3-1. Field Communicator Connections
3.3.3
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. Refer to Figure
3-11 on page 43 for correct mounting orientation.
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 3-11 on page 43, keeping drain/vent
connections on the bottom for gas service and on the top for liquid service.
3.3.4
Environmental considerations
32
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.

Draft range considerations
Installation
For the Rosemount 2051CD0 draft range pressure transmitter, it is best to mount the
transmitter with the isolators parallel to the ground. See Figure 3-3 on page 34 for a draft range
installation example on a 304 manifold. Installing the transmitter in this way reduces oil head
effect.

Tilting of the transmitter may cause a zero shift in the transmitter output, but can be eliminated
by performing a trim procedure.

A. Isolators
Reducing process noise
Rosemount 2051CD0 draft transmitters are sensitive to small pressure changes. Increasing the
damping will decrease output noise, but will further reduce response time. In gage applications,
it is important to minimize pressure fluctuations to the low side isolator.
Output damping
The Damping command introduces a delay in processing which increases the response time of
the transmitter; smoothing variations in output readings caused by rapid input changes. In the
Rosemount 2051 Wireless pressure transmitter, damping only takes effect when the device is
placed in high power refresh mode and during calibration. In normal power mode, the effective
damping is 0. Note that when the device is in high power refresh mode, battery power will be
depleted rapidly. Determine the appropriate damp setting based on the necessary response
time, signal stability, and other requirements of the loop dynamics of your system. The damping
value of your device is user selectable from 0 to 60 seconds.
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.

Installation procedures
For dimensional drawing information refer to Appendix A: Specifications and Reference Data on
page 89.
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.
Note
Most transmitters are calibrated in the horizontal position. Mounting the transmitter in any
other position will shift the zero point to the equivalent amount of liquid head pressure caused
by the varied mounting position. To reset zero point, refer to “Sensor Trim” on page 68.
Consider 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:
1.

- -in. hex wrench.
Loosen the housing rotation set screw using a -----
2.
Retighten the housing rotation set screw.

Impulse piping
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: 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 depends on the process
itself. Use the following guidelines to determine transmitter location and placement of impulse
piping:
Installation

Keep impulse piping as short as possible.

For liquid service, slope the impulse piping at least 1 inch per foot (8 cm per m) upward
from the transmitter toward the process connection.

For gas service, slope the impulse piping at least 1 inch per foot (8 cm per 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.

Keep the liquid head balanced on both legs of the impulse piping.

Avoid conditions that might allow process fluid to freeze within the process flange.
41
Reference Manual
Section 3: Installation
00809-0100-4102, Rev AA
May 2013
Mounting Requirements
Refer to Figure 3-11 on page 43 for examples of the following mounting configurations:
Liquid Flow Measurement

Place taps to the side of the line to prevent sediment deposits on the process isolators.

Mount the transmitter beside or below the taps so gases 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 to drain liquid into the process line.
Steam Flow Measurement

Place taps to the side of the line.

Mount the transmitter below the taps to ensure that impulse piping will remain filled
with condensate.

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
Coplanar process flanges must not exceed 250 °F (121 °C) for transmitters with silicone fill, or
185 °F (85 °C) for inert fill. For vacuum service, these temperature limits are reduced to 220 °F
(104 °C) for silicone fill and 160 °F (71 °C) for inert fill.

Process connections
Coplanar or traditional process connection
Install and tighten all four flange bolts before applying pressure to avoid leakage. 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 adapters
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 101 for the distance between pressure connections. This
distance may be varied ±1/4 in. (6.4 mm) by rotating one or both of the flange adapters.
To install adapters to a Coplanar flange, perform the following procedure:
Installation
43
Reference Manual
Section 3: Installation
00809-0100-4102, Rev AA

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 module using the longer
of the bolts supplied.
4.
Tighten the bolts. Refer to “Flange bolts” on page 37 for torque specifications.
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.

Note
PTFE O-rings should be replaced if the flange adapter is removed.
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 Section 6: Troubleshooting on page 83.
3.4.4
Inline process connection
Inline gage transmitter orientation
Interfering or blocking the atmospheric reference port will cause the transmitter to output
erroneous pressure values.
The low side pressure port on the inline gage transmitter is located in the neck of the
transmitter, behind the housing. The vent path is 360 degrees around the transmitter between
the housing and sensor (See Figure 3-12).
Keep the vent path free of any obstruction, such as paint, dust, and lubrication by mounting the
transmitter so that the process can drain away.

Calibration overview
Calibrating a 2051 Wireless transmitter may include the following procedures:

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.
The Rosemount 2051 sensor module 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.
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.

5.3.1
Determining necessary Sensor Trims
Bench calibrations allow for calibrating the instrument for its desired range of operation.
Straight forward connections to pressure source allow for a full calibration at the planned
operating points. Exercising the Transmitter over the desired pressure range allows for
verification of the output value. “Sensor Trim” on page 68 discusses how the trim operations
change the calibration. It is possible to degrade the performance of the transmitter if a trim is
done improperly or with inaccurate equipment. The transmitter can be set back to factory
settings using the Recall Factory Trim command in “Recall Factory Trim—Sensor Trim” on
page 70.

For transmitters that are field installed, the manifolds discussed in “Rosemount 304, 305 and
306 integral manifolds” on page 47 allow the differential transmitter to be zeroed using the zero
trim function. Both 3-valve and 5-valve manifolds are discussed. This field calibration will
eliminate any pressure offsets caused by mounting effects (head effect of the oil fill) and static
pressure effects of the process.
Determine the necessary trims with the following steps.

Compensating for Span line pressure effects (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 0 through 3) do not require this procedure
because optimization occurs at the sensor.
The systematic span shift caused by the application of static line pressure is -0.95% of reading
per 1000psi (69 bar) for Range 4 transmitters, and -1% of reading per 1000psi (69 bar) for Range
5 transmitters. Using the following procedure, the span effect can be corrected to ±0.2% of
reading per 1000 psi (69 bar) for line pressures from 0 to 3626 psi (0 to 250 bar).
Use the following example to compute correct input values.

Example
A range 4 differential pressure HART transmitter (2051CD4...) will be used in an application with
a static line pressure of 1200 psi (83 bar). The transmitter output is ranged with the Lower
Range Value at 500 inH20 (1, 2 bar) and the Upper Range Value at 1500 inH20 (3, 7 bar). To
correct for systematic error caused by high static line pressure, first use the following formulas
to determine the corrected values for the high trim value.
High Trim Value:
HT = (URV - (S/100 x P/1000 x LRV))
Where:
HT =
Corrected High Trim Value
URV =
Upper Range Value
S=

P=

URV =

P=

LT =
1500 - (-0.95%/100 x 1200 psi/1000 psi x 1500 inH2O)
LT =
1517.1 inH20
In this example:
Complete the Upper Sensor Trim procedure as described in “Sensor Trim” on page 68. In the
example above, at step 4, apply the nominal pressure value of 1500 inH20. However, enter the
calculated correct upper Sensor Trim value of 1517.1 inH20 with a Field Communicator.
Note
The Range Values for the upper and lower range points should be at the nominal URV and LRV. In
the example above, the values are 1500 inH20 and 500 inH20 respectively. Confirm the values
on the HOME screen of the Field Communicator. Modify, if needed, by following the steps in
“Set range points” on page 19.

Trim the pressure signal
5.4.1
Sensor Trim Overview
A Sensor Trim corrects the pressure offset and pressure range to match a pressure standard. The
Upper Sensor Trim corrects the pressure range and the Lower Sensor Trim (Zero Trim) corrects
the pressure offset. An accurate pressure standard is required for full calibration. A zero trim can
be performed if the process is vented, or the high and low side pressure are equal (for
differential pressure transmitters).
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
Operation and maintenance

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, ensure that the equalizing valve is open and all wet legs are filled
to the correct levels. Line pressure should be applied to the transmitter during a zero trim to
eliminate line pressure errors. Refer to “Manifold operation” on page 50.
Note
Do not perform a zero trim on 2051 Wireless absolute pressure transmitters. Zero trim is zero
based, and absolute pressure transmitters reference absolute zero. To correct mounting
position effects on a 2051 Wireless 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 two-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.
During a trim operation, the 2051 Wireless is placed in high power refresh mode, which
provides frequent pressure measurement updates and allows the configured damping to take
effect. This behavior allows for more accurate calibration of the device. When the device is in
high power refresh mode, the battery power supply will be depleted more rapidly.

Compensating for Line Pressure (Range 4 and Range 5)
The Rosemount 2051 Wireless 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 Wireless differential pressure transmitters (Ranges 1, 2, and 3) do not
require this procedure because optimization occurs in the sensor.
Applying high static pressure to the 2051 Wireless 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 68.
The following specifications show the static pressure effect for the 2051 Wireless Range 4 and
Range 5 transmitters used in differential pressure applications:

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.
Use the following example to compute corrected input values.
Example
A transmitter with model number 2051_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).
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
Where:
LT =
Corrected Low Trim Value
LRV =
Lower Range Value
S=
–(Span shift per specification)
P=
Static Line Pressure
HT = URV + S x (URV) x P
Where:
HT =
Corrected High Trim Value
URV =
Upper Range Value
S=
–(Span shift per specification)
P=
Static Line Pressure
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 =
500 + (0.01/1000)(500)(1200)
LT =
506 inH2O (1.26 bar)
To calculate the high trim (HT) value:
HT =
1500 + (0.01/1000)(1500)(1200)
HT =
1518 inH2O (3.78 bar)
Complete a 2051 Wireless sensor trim and enter the corrected values for low trim (LT) and high
trim (HT), refer to “Sensor Trim” on page 68.
Enter the corrected input values for low trim and high trim through the Field Communicator
keypad after you apply the nominal value of pressure as the transmitter input.
Note
After sensor trimming 2051 Wireless Range 4 and 5 transmitters for high differential pressure
applications, verify that the Lower and Upper Operating points are at nominal values using the
Field Communicator.

Damping
The Damping command introduces a delay in processing which increases the response time of
the transmitter; smoothing variations in output readings caused by rapid input changes. In the
2051 Wireless pressure transmitter, damping only takes effect when the device is placed in high
power refresh mode and during calibration. In normal power mode, the effective damping is 0.
Note that when the device is in high power refresh mode, battery power will be depleted rapidly.

All recommended practices should be followed to ensure highest data reliability. Deviation from
these best practices may require device repeaters in the network to maintain 99% data
reliability. The following are guidelines to achieve the best possible Smart Wireless Network.
D.1
1.
Each wireless network field should be scoped to a single process unit.
2.
Minimize the number of hops to the Gateway in order to reduce latency. A minimum of
five wireless instruments should be within effective range of the Smart Wireless
Gateway.
3.
Each device in the network should have at minimum three devices with potential
communication paths. A mesh network gets its reliability from multiple
communication pathways. Ensuring each device has multiple neighbors within range
will result in the most reliable network.
4.
Have 25 percent of wireless instruments in the network within range of Smart Wireless
Gateway. Other enhancing modifications include creating a higher percentage of
devices within effective range of the gateway to 35 percent or more. This clusters more
devices around the gateway and ensures fewer hops and more bandwidth available to
WirelessHART devices with fast scan rates.
5.
Effective range is determined by type of process unit and the density of the
infrastructure that surrounds the network.
Effective range
Heavy Obstruction: 100 ft. (30 m). Typical heavy density plant environment. Cannot drive a
truck or equipment through.
Medium Obstruction: 250 ft. (76 m). Typical light process areas, lots of space between
equipment and infrastructure.
Light Obstruction: 500 ft. (152 m). Typical of tank farms. Despite tanks being big obstructions
themselves, lots of space between and above makes for good RF propagation.
Line of Sight: 750 ft. (230 m). No obstructions between WirelessHART devices and devices
mounted a minimum of 6 ft. (2 m) above ground or obstructions.
