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 HART Revision 5 and 7 Reference Manual
for more instructions. This manual is also available electronically at Emerson.com/Rosemount.

WARNING

Explosions

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 Product certifications for any
restrictions associated with a safe installation.

Before connecting a handheld communicator in an explosive atmosphere, ensure the instruments
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

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.

Physical access

Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end
users’ equipment. This could be intentional or unintentional and needs to be protected against.

Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.

Bolts are typically carbon steel or stainless steel. 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.

Carbon steel bolts do not require lubrication, and the stainless steel bolts are
coated with a lubricant to ease installation. However, do not apply additional
lubricant when installing either type of bolt.

2.1.6 Environmental seal for housing

For NEMA® 4X, IP66, and IP68 requirements, use thread sealing (PTFE) tape
or paste on male threads of conduit to provide a water and dust tight seal.
Consult factory if other ingress protection ratings are required.

For M20 threads, install conduit plugs to full thread engagement or until
mechanical resistance is met.

2.1.7 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 degrees around the transmitter between the housing and
sensor (see Figure 2-12).

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.

Figure 2-12: Inline Gage Low Side Pressure Port

A. Low side pressure port (atmospheric reference)

2.1.8 Install high pressure coned and threaded connection

The transmitter comes with an autoclave connection designed for pressure
applications. Follow the steps below to properly connect the transmitter to
your process.

Procedure

1. Apply a process-compatible lubricant to the gland nut threads.

2. Slip the gland nut onto the tube; then thread the collar onto the tube
end.

The collar is reverse threaded.

3. Apply a small amount of process-compatible lubricant to the tube
cone to help prevent galling and facilitate sealing. Insert the tubing
into the connection and use the fingers to tighten the bolts.

4. Tighten the gland nut to a torque of 25 ft-lb.

Note

A weep hole has been designed into the transmitter for safety and
leak detection. If fluid begins to leak from the weep hole, isolate the
process pressure, disconnect the transmitter, and reseal until the
leak is resolved.

2.2 Consider housing rotation

To improve field access to wiring or to better view the optional LCD display:

Figure 2-13: Housing Rotation

A. Housing rotation set screw (5/64-in.)

Procedure

1. Loosen the housing rotation set screw using a 5/64-in. hex wrench.

2. Rotate the housing clockwise to the desired location.

3. If the desired location cannot be achieved due to thread limit, rotate
the housing counterclockwise to the desired location (up to 360°
from thread limit).

4. Retighten the housing rotation set screw to no more than 7 in-lb
when it reaches the desired location.

operating on battery backup. Emerson recommends a minimum of 12 Vdc
under normal operating conditions and shielded twisted pair Type A cable.

Procedure

1. To power the transmitter, connect the power leads to the terminals
indicated on the terminal block label.

D. Insulate shield

E. Connect shield back to the power supply ground

Note

The Rosemount 3051 power terminals are polarity insensitive, which
means the electrical polarity of the power leads does not matter
when connecting to the power terminals. If polarity sensitive devices
are connected to the segment, follow terminal polarity. When wiring
to the screw terminals, Emerson recommends using crimped legs.

2. Ensure full contact with terminal block screw and washer. When
using a direct wiring method, wrap wire clockwise to ensure it is in
place when tightening the terminal block screw.
