Rosemount™ 3051 Pressure Transmitter

Quick Start Guide February 2019

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.

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.

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.

position is the opposite side of bracket holes.

CAUTION

Over rotation of housing may cause damage to module
communication cable.

2.2 Set the switches

Procedure

1.
Set alarm and security switch configuration before installation as

shown in Figure 2-8.

2. The alarm switch sets the analog output alarm to high or low.

3. Default alarm is high.

4. The security switch allows (unlocked symbol) or prevents (locked
symbol) any configuration of the transmitter.

5. Default security is off (unlocked symbol).

Use the following procedure to change the switch configuration:

6. If the transmitter is installed, secure the loop, and remove power.

7. Remove the housing cover opposite the field terminal side. Do not
remove the instrument cover in explosive atmospheres when the
circuit is live.

8. Slide the security and alarm switches into the preferred position using
a small screwdriver.

9. Reattach the transmitter cover. The cover must be fully engaged to
comply with explosion-proof requirements.

Shielded twisted pair cable should be used for best results. Use 24 AWG or
larger wire that does not exceed 5,000 ft. (1500 m) 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.
