Rosemount™ 3051 Pressure Transmitter
NOTICE
This guide provides basic guidelines for Rosemount™ 3051 Transmitters. It does not provide
instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-proof,
Flameproof, or intrinsically safe (I.S.) installations. Refer to Rosemount 3051 Reference Manual for
more instructions. This manual is also available electronically at Emerson.com/Rosemount.
WARNING
Explosions could result in death or serious injury.
Installation of device in an explosive environment must be in accordance with appropriate local,
national, and international standards, codes, and practices. Review the approvals section of the
Rosemount 3051 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.
WARNING
Process leaks
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
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.
Conduit/cable entries
Unless otherwise marked, the conduit/cable entries in the housing enclosure use a ½–14 NPT
form. Only use plugs, adapters, glands, or conduit with a compatible thread form when closing
these entries.
Entries marked M20 are M20 x 1.5 thread form. On devices with multiple conduit entries, all
entries will have the same thread form.

1 System readiness
Confirm HART revision capability
•If using HART-based control or asset management systems, confirm the
HART capability of those systems prior to transmitter installation. Not all
systems are capable of communicating with HART Revision 7. This
transmitter can be configured for either HART Revision 5 or 7.
•For instructions on how to change the HART revision of your transmitter,
see Switch HART revision mode.
1.1 Confirm correct device driver
•Verify the latest device driver (DD/DTM™) is loaded on your systems to
ensure proper communications.
•Download the latest device driver at Emerson.com or
Fieldcommgroup.org.

2.1.4 Bolting considerations
If the transmitter installation requires assembly of the process flanges,
manifolds, or flange adapters, follow the 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
2-5 illustrates common transmitter assemblies with the bolt length required
for proper transmitter assembly.

A. Transmitter with coplanar flange
B. Transmitter with coplanar flange and optional flange adapters
C. Transmitter with traditional flange and optional flange adapters
D. Transmitter with coplanar flange and optional manifold and flange
adapters
Bolts are typically carbon steel (CS) or stainless steel (SST). Confirm the
material by viewing the markings on the head of the bolt and referencing
Table 2-1. If bolt material is not shown in Table 2-1, contact a local Emerson
representative for more information.
Use the following bolt installation procedure:
Procedure
1. CS bolts do not require lubrication and the SST 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 Table 2-1 for initial torque value.
Quick Start Guide February 2019

4. Torque the bolts to the final torque value using the same crossing
pattern. See Table 2-1 for final torque value.
5. Verify that the flange bolts are protruding through the isolator plate
before applying pressure.

2.1.5 In-line gage transmitter orientation
The low side pressure port (atmospheric reference) on the in-line 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 2-6)
Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so that the process can
drain away.

2.1.6 Consider housing rotation
To improve field access to wiring or to better view the optional LCD display:
Procedure
1. Loosen the housing rotation set screw using a -in. hex wrench.
2. Turn the housing left or right maximum up to 180° from its original
position.(1)
Note
Over-rotating can damage the transmitter.
3. Re-tighten the housing rotation set screw to no more than 7 in-lb
when desired location is reached.
