Failure to follow these installation guidelines could result in death or serious injury:

 Make sure only qualified personnel perform the installation.

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 this manual for any restrictions associated with a safe installation.

 Before connecting a Field Communicator in an explosive atmosphere, ensure the

instruments are installed in accordance with intrinsically safe or non-incendive field
wiring practices.

 Verify that the operating atmosphere of the transmitter is consistent with the

appropriate hazardous locations certifications.

Process leaks could result in death or serious injury.

 Install and tighten process connectors before applying pressure.
 Do not attempt to loosen or remove process connectors while the transmitter is in

service.

Electrical shock can result in death or serious injury.

 Avoid contact with the leads and 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
Wireless Gateway has been installed and is functioning properly. 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.

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.

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.

Introduction

Reference Manual

00809-0100-4102, Rev AA

The Power Module contains one “D” size primary lithium/thionyl chloride battery (Green Power
Module, model number 701PGNKF). Each Power Module contains approximately 5 grams of
lithium. Under normal conditions, the Power Module materials are self-contained and are not
reactive as long as the batteries and the module integrity are maintained. Care should be taken
to prevent thermal, electrical or mechanical damage. Contacts should be protected to prevent
premature discharge. Power Module hazards remain when cells are discharged.

Power Module should be stored in a clean and dry area. For maximum battery life, storage
temperature should not exceed 30° C.

Emerson Process Management Instrument and Valves Response Center representatives will
explain the additional information and procedures necessary to return goods exposed to
hazardous substances.

1.4 Product Recycling/Disposal

Recycling of equipment and packaging should be taken into consideration and disposed of in
accordance with local and national legislation/regulations.

The 2051 Wireless has two output settings: Linear and Square Root. Activate the square root
output option to make output proportional to flow. As input approaches zero, the 2051
Wireless automatically switches to linear output in order to ensure a more smooth, stable
output near zero (see Figure 2-2).

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.

To select the output transfer function:

1. From the Home screen, select 2: Configure.

2.8.3 Damping

Section 2: Configuration

June 2012

Fast Keys

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.
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 25.6 seconds.

3.3 Considerations

3.3.1 General

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

Power Up Sequence

The Power Module should not be installed on any wireless device until the Smart Wireless
Gateway is installed and functioning properly. 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 High Speed Operation 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

3.4 Installation Procedures

For dimensional drawing information refer to “Dimensional Drawings” on page 83.

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

See “Consider Housing Rotation” on page 34.

Power Module Side of Electronics Housing

Mount the transmitter so the Power Module side is accessible. Clearance of 2.75-in. (70 mm) is
required for cover removal.

Section 3: Installation

June 2012

Circuit Side of Electronics Housing

Provide 0.75 in. (19 mm) of clearance for units with out an LCD display. Three inches of
clearance is required for cover removal if a meter is installed.

Cover Installation

Always ensure a proper seal by installing the electronics housing cover(s) so that polymer
contacts polymer. Use Rosemount O-rings.

3.4.1 Mount the Transmitter

Mounting Brackets

Facilitate mounting transmitter to a 2-in. pipe, or to a panel. The B4 Bracket (SST) option is
standard for use with the Coplanar and In-Line flanges. “Coplanar Flange Mounting Configura­tions” on page 83 shows bracket dimensions and mounting configurations for the B4 option.

Options B1–B3 and B7–B9 are sturdy, epoxy/polyester-painted brackets designed for use with
the traditional flange. The B1–B3 brackets have carbon steel bolts, while the B7–B9 brackets
have stainless steel bolts. The BA and BC brackets and bolts are stainless steel. The B1/B7/BA
and B3/B9/BC style brackets support 2-inch pipe-mount installations, and the B2/B8 style
brackets support panel mounting.

Installation

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 caused by the
varied mounting position. To reset zero point, refer to “Sensor Trim” on page 49.

Position the antenna such that it is vertical, typically straight up (antenna may be pointed down
as well.)

Impulse Piping

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:

 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

 For gas service, slope the impulse piping at least 1 inch per foot (8 cm per m) downward

 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.

from the transmitter toward the process connection.

 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 SuperModule 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.

Mounting Requirements

Refer to Figure 3.4.2 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

 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.

3.4.2 Process Connections

2051 Wireless transmitter flange process connection size is 1/4–18 NPT. Flange adapters with

1

/2–14 NPT connections are available as the D2 option. Use your plant-approved lubricant or
sealant when making the process connections. The process connections on the transmitter

5.2 Calibration

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 2051 sensor module 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.

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.

Reference Manual

00809-0100-4102, Rev AA

Note

A Field Communicator or AMS is required for all sensor and output trim procedures.

Rosemount 2051C Range 4 and Range 5 transmitters require a special calibration procedure
when used in differential pressure applications under high static line pressure.

5.2.1 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, ensure that the equalizing valve is open and all wet legs are filled
to the correct levels.

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.

48

Operation and Maintenance

Reference Manual

00809-0100-4102, Rev AA

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.

5.2.2 Zero Trim

Section 5: Operation and Maintenance

5.2.5 Line Pressure Effect (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) for Ultra performance transmitter. Zero effect error
calculation:

± {0.05 + 0.1 x [3 kpsi - 2 kpsi]} = ± 0.15% of the upper range limit

Span Effect

Refer to “Line Pressure Effect” on page 73.

5.2.6 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.

50

Operation and Maintenance

Reference Manual

00809-0100-4102, Rev AA

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 49.

The following specifications show the static pressure effect for the 2051 Wireless 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

Section 5: Operation and Maintenance

June 2012

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.

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 inH
(1,2 bar) and 20 mA at 1500 inH

O (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

In this example:

Reference Manual

00809-0100-4102, Rev AA

URV = 1500 inH

LRV = 500 inH

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 inH

To calculate the high trim (HT) value:

HT = 1500 + (0.01/1000)(1500)(1200)

HT = 1518 inH

O (3.74 bar)

2

O (1.25 bar)

2

O (1.26 bar)

O (3.78 bar)

2

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 49.

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.

The V-Seal must be installed at the bottom of the housing.

6.4.1 Reassemble the Process Flange

1. Inspect the Teflon sensor module o-rings. If the o-rings are not damaged, reuse them.
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 flange on the sensor module. To hold the process flange in place,
install the two alignment screws to finger tight (screws are not pressure retaining). Do
not overtighten; this will affect module-to-flange alignment.

Section 6: Troubleshooting

June 2012

3. Install the appropriate flange bolts.

a. If the installation requires a

b. If the installation requires a

/2–14 NPT mounting, use four 2.88-in. process

flange/adapter bolts. For gage pressure configurations, use two 2.88-in. bolts and two

1.75-in. bolts. Go to Step d.

c. If the installation uses a manifold (differential pressure applications only), use

appropriate bolts. Go to Step e.

d. Hold the flange adapters and adapter o-rings in place while finger-tightening the bolts.

Go to Step g.
e. Align the process flange with the manifold.
f. Finger tighten the bolts.
g. Tighten the bolts to the initial torque value using a crossed pattern. See Ta bl e 6 - 4 for

appropriate torque values.
h. Tighten the bolts to the final torque value using a crossed pattern. See Ta b le 6 -4 for

appropriate torque values. When fully tightened, the bolts should extend through the

top of the module housing.
i. If the installation uses a manifold, then install flange adapters on the process end of the

manifold using the 1.75-in. flange bolts supplied with the transmitter.

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.
