IMPORTANT NOTICE
This installation guide provides basic guidelines for Rosemount
2051 transmitters. It does not provide instructions for configuration, diagnostics,
maintenance, service, troubleshooting, Explosion-proof, Flameproof, or intrinsically safe
(I.S.) installations. Refer to the 2051 reference manual (document number
00809-0100-4101) for more instruction. This manual is also available electronically on
www.emersonprocess.com/rosemount.
WARNING
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.
• In an Explosion-proof/Flameproof installation, do not remove the transmitter covers
when power is applied to the unit.
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.
Conduit/Cable Entries
• Unless marked, the conduit/cable entries in the transmitter housing use a 1/2-14 NPT
thread form. Only use plugs, adapters, glands or conduit with a compatible thread
form when closing these entries.

C. Bolting Considerations
If the transmitter installation requires assembly of the process flanges, manifolds, or flange
adapters, follow these assembly guidelines to ensure a tight seal for optimal performance
characteristics of the transmitters. Use only bolts supplied with the transmitter or sold by
Emerson as spare parts. Figure 1 illustrates common transmitter assemblies with the bolt
length required for proper transmitter assembly.

Bolts are typically carbon steel or stainless steel. Confirm the material by viewing the
markings on the head of the bolt and referencing Figure 2. If bolt material is not shown in
Figure 2, contact the local Emerson Process Management representative for more
information.
Use the following bolt installation procedure:
1. Carbon steel bolts do not require lubrication and the stainless steel bolts are coated with
a lubricant to ease installation. However, no additional lubricant should be applied when
installing either type of bolt.
2. Finger-tighten the bolts.
3. Torque the bolts to the initial torque value using a crossing pattern. See Figure 2 for initial
torque value.
4. Torque the bolts to the final torque value using the same crossing pattern. See Figure 2
for final torque value.
5. Verify that the flange bolts are protruding through the isolator plate before applying
pressure.

E. Inline Gage Transmitter Orientation
The low side pressure port (atmospheric reference) on the inline gage transmitter is located
in the neck of the transmitter, behind the housing. The vent path is 360° around the
transmitter between the housing and sensor. (See Figure 3.)
Keep the vent path free of any obstruction, including but not limited to paint, dust, and
lubrication by mounting the transmitter so that the contaminants can drain away.

(atmospheric reference)
STEP 2: CONSIDER HOUSING ROTATION
To improve field access to wiring or to better view the optional LCD display:
1. Loosen the housing rotation set screw.
2. First rotate the housing clockwise to the desired location. If
the desired location cannot be achieved due to thread limit,
rotate the housing counter clockwise to the desired location
(up to 360° from thread limit).
3. Retighten the housing rotation set screw.

(5/64-inch)
STEP 3: SET THE JUMPERS
If alarm and security jumpers are not installed, the transmitter will operate normally with the
default alarm condition alarm high and the security off.
1. If the transmitter is installed, secure the loop, and remove power.
2. Remove the housing cover opposite the field terminal side. Do not remove the
instrument cover in explosive atmospheres when the circuit is live.
3. Reposition the jumper. Avoid contact with the leads and the terminals. See Figure 4 for
the location of the jumper and the ON and OFF positions.
4. Reattach the transmitter cover. The cover must be fully engaged to comply with
explosion-proof requirements.

STEP 6: TRIM THE TRANSMITTER
NOTE
Transmitters are shipped fully calibrated per request or by the factory default of full scale
(span = upper range limit).
Zero Trim
A zero trim is a single-point adjustment used for compensating mounting position effects.
When performing a zero trim, ensure that the equalizing valve is open and all wet legs are
filled to the correct level.
There are two methods to compensate for mounting effects:
• Field Communicator
• Transmitter Zero Adjustment Buttons
Select the appropriate method and follow instructions below.
Using the Field Communicator
If zero offset is within 3% of URL, follow the “Using the Field Communicator” instructions
below. This zero trim will affect the 4-20 mA value, the HART PV, and the display value.
HART Fast Keys
1, 2, 3, 3, 2
Steps
1. Equalize or vent the transmitter and connect Fieldbus communicator.
2. At the menu, input the Fast Key sequence.
3. Follow the commands to perform a zero trim.
Using the Transmitter Zero Adjustment Buttons
Using the Transmitter Zero Adjustment Buttons, the Lower Range Value (LRV) will be set to
the pressure applied to the transmitter. This adjustment will affect the 4-20 mA value only.
Perform the following steps to perform a rerange using the zero adjustment buttons.
1. Loosen the certifications label screw and slide the label to expose the zero adjustment
buttons. See Figure 9.
2. Set the 4 mA point by pressing the zero button for 2 seconds. Verify that the output is 4
mA. The optional LCD will display ZERO PASS.

SAFETY INSTRUMENTED SYSTEMS
The following section applies to 2051 transmitters used in SIS applications.
NOTE
Transmitter output is not safety-rated during the following: configuration changes, multidrop,
loop test. Alternative means should be used to ensure process safety during transmitter
configuration and maintenance activities.
DCS or safety logic solver must be configured to match transmitter configuration. Figure 10
identifies the two alarm level available and their operation values. Position the alarm switch
to the required HI or LO alarm position.
Installation
No special installation is required in addition to the standard installation practices outlined in
this document. Always ensure a proper seal by installing the electronics housing cover(s) so
that metal contacts metal.
The loop must be designed so the terminal voltage does not drop below 10.5 Vdc when the
transmitter output is 22.5 mA.
Position the security switch to the “ON” position to prevent accidental or deliberate change
of configuration data during normal operation.
Configuration
Use any HART-compliant master to communicate with and verify configuration of the 2051.
User-selected damping will affect the transmitters ability to respond to changes in the
applied process. The damping value + response time must not exceed the loop
requirements.
