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, Flame-Proof, or intrinsically safe
(I.S.) installations. Refer to the 2051 reference manual (document number
00809-0200-4101) 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 field 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/Flame-Proof 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.
Figure 1. Common Transmitter Assemblies
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 initialtorque 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.

D. O-rings with Flange Adapters
WARNING
Whenever the flanges or adapters are removed, visually inspect the 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 and alignment screws after installation to compensate for seating of the
PTFE o-ring.

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.

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.

STEP 2: TAGGING
STEP 3: CONSIDER HOUSING ROTATION
To improve field access to wiring or to better view the optional LCD display:
Commissioning (Paper) Tag
To identify which device is at a particular location use
the removable tag provided with the transmitter. Ensure
that the physical device tag (PD Tag field) is properly
entered in both places on the removable
commissioning tag and tear off the bottom portion for
each transmitter.
NOTE
The device description loaded in the host system must
be at the same revision as this device. The device
description can be downloaded from
www.emersonprocess.com/rosemount.
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.

STEP 4: CONNECT THE WIRING AND POWER UP
Power Supply
The transmitter requires between 9 and 32 V dc (9 and 15 V dc for FISCO) to operate and
provide complete functionality.
Power Conditioner
A fieldbus segment requires a power conditioner to isolate the power supply filter and
decouple the segment from other segments attached to the same power supply.
Grounding
Signal wiring of the fieldbus segment can not be grounded. Grounding out one of the signal
wires will shut down the entire fieldbus segment.
Shield Wire Ground
To protect the fieldbus segment from noise, 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.
It is important that the instrument cable shield:
• be trimmed close and insulated from touching the transmitter housing
• be connected to the next shield if cable is routed through a junction box
• be connected to a good earth ground at the power supply end
Use of ordinary copper wire of sufficient size to
ensure that the voltage across the transmitter
power terminals does not drop below 9 vdc. To
power the transmitter, connect the power leads to
the terminals indicated on the terminal block label.
The power terminals are polarity insensitive, which
means the electrical polarity of the power leads
does not matter when connecting to the power
terminals. When wiring to the screw terminals, the
use of crimped legs is recommended. Tighten the
terminal screws to ensure adequate contact. No
additional power is needed.

STEP 5: VERIFY CONFIGURATION
Each Foundation fieldbus host or configuration tool has a different way of displaying and
performing configurations. Some use Device Descriptions (DD) or DD methods for
configuration and to display data consistently across platforms. There is no requirement that
a host or configuration tool support these features. Use the following block examples to do
basic configuration to the transmitter. For more advanced configurations see the 2051
reference manual (document number 00809-0200-4101).
NOTE
DeltaV users should use DeltaV Explorer for the Resource and Transducer blocks and
Control Studio for the Function Blocks.
To configure the AI Block

Use the Pressure, DP Flow, and DP Level examples for guides.
