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 the Rosemount 3051 HART Revision 5 and 7 Reference Manual
instruction. This manual is also available electronically on Emerson.com/Rosemount
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 prac tices. Review the approvals section of the Rosemount
3051 Reference Manual
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
Entries marked “M20” are M20 ⫻ 1.5 thread form. On devices with multiple conduit entries, all entries will
have the same thread form.
Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these entries.

1.1 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 protocol. 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
page 13.

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

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 on page 7.
If bolt material is not shown in Table 2, contact a local Emerson 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 Table 2 for initial torque value.
4. Torque the bolts to the final torque value using the same crossing pattern.
See Table 2 for final torque value.
5. Verify the flange bolts are protruding through the isolator plate before
applying pressure.

Environmental seal for housing
Thread sealing (PTFE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seal and meets requirements of NEMA
Type 4X, IP66, and IP68. 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.

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 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 process can
drain away.
Figure 3. In-line Gage Low Side Pressure Port
A. Low side pressure port (atmospheric reference)
Installing high pressure coned and threaded connection
The transmitter comes with an autoclave connection designed for high
pressure applications. Follow the steps below to properly connect the
transmitter to your process:
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).

Quick Start Guide

3. Apply a small amount of process-compatible lubricant applied to the tube
cone to help prevent galling and facilitate sealing. Insert the tubing into the
connection and tighten finger tight.
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:
1. Loosen the housing rotation set screw using a
2. Turn the housing left or right maximum up to 180° from its original
position.
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.

Shielded twisted pair cable should be used for best results. Use 24 AWG or larger
wire that does not exceed 5,000 feet (1500 meters) in length. If applicable,
install wiring with a drip loop. Arrange the drip loop so the bottom is lower than
the conduit connections and the transmitter housing.

Installation of the transient protection terminal block does not provide transient protection unless
the Rosemount 3051 case is properly grounded.
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical
equipment.
Do not connect the powered signal wiring to the test terminals. Power could damage the test diode
in the terminal block.
Use the following steps to wire the transmitter:
1. Remove the housing cover on the FIELD TERMINALS side.
2. Connect the positive lead to the “+” terminal (PWR/COMM) and the negative
lead to the “–” terminal.
3. Tighten the terminal screws to ensure full contact with the 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.
Note
The use of a pin or ferrule wire terminal is not recommended as the connection may be
more susceptible to loosening over time or under vibration.
4. Ground housing to fulfill local grounding regulations.
5. Ensure proper grounding. It is important that the instrument cable shield be:
a. Trimmed close and insulated from touching the transmitter housing
b. Connected to the next shield if cable is routed through a junction box
c. Connected to a good earth ground at the power supply end
6. If transient protection is needed, refer to section “Grounding for transient
terminal block” on page 11 for grounding instructions.
7. Plug and seal unused conduit connections.
8. Replace the housing cover.
