1 About this guide
This installation guide provides basic guidelines for Rosemount™ 3051P
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 Rosemount 3051P Reference
Manual for more instruction. This manual is also available electronically on
Emerson.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. Review the approvals section of the
Rosemount 3051P Reference Manual for any restrictions associated with
a safe installation.
Do not remove the transmitter cover in explosive atmospheres when the
circuit is live.
Process leaks could result in death or serious injury.
To avoid process leaks, only use the O-ring designed to seal with the
corresponding flange adapter.
Electrical shock could cause 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.
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.

2.1 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. 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.
2.2 Confirm correct device driver
Procedure
1. Verify the latest Device Driver (DD/DTM™) is loaded on your systems
to ensure proper communications.
2. Reference Emerson.com or FieldCommGroup.org for the lated DD.
3. Select desired product and download the DD.
a) Reference Table 1, for the correct DD.

(1) NAMUR revision is located on the hardware tag of the device. Differences in level 3 changes,
signified above by xx, represent minor product changes as defined per NE53. Compatibility
and functionality are preserved and product can be used interchangeably.
(2) HART software revision can be read using a HART capable configuration tool. Value shown
is minimum revision that could correspond to NAMUR revisions.
(3) Device driver file names use device and DD revision, e.g. 10_01. HART Protocol is designed
to enable legacy device driver revisions to continue to communicate with new HART devices.
To access new functionality, the new device driver must be downloaded. It is recommended
to download new device driver files to ensure full functionality.

3 Mount the transmitter
Mount directly to the impulse line without using an additional mounting
bracket or mount directly to a wall, panel, or two-inch pipe using an optional
mounting bracket.
Figure 3-1: Transmitter Direct Mounting
Do not apply torque directly to the electronics housing. To avoid damage,
apply torque only to the hex-shaped process connection.

3.1 Mount the transmitter in liquid applications
Procedure
1. Place taps to the side of the line.
2. Mount beside or below the taps.
3. Mount the transmitter so the drain/vent valves are oriented upward.

In-line
3.2 Mount the transmitter in gas applications
Procedure
1. Place taps in the top or side of the line.
2. Mount beside or above the taps.

3.3 Mount the transmitter in steam applications
Procedure
1. Place taps to the side of the line.
2. Mount beside or below the taps.
3. Fill impulse lines with water.

3.4 Environmental seal for housing
Thread sealing (PFTE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seals 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.
3.5 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 3-6.)
Quick Start Guide May 2019
8 Emerson.com/Rosemount
CAUTION
Keep the vent path free of any obstruction, including but not limited to
paint, dust, and lubrication by mounting the transmitter so the
contaminants can drain away.

4 Set the switches
Set alarm and security switch configuration before installation as shown in
Figure 4-1.
•The alarm switch sets the analog output alarm to high or low. Default
alarm is high.
•The security switch allows ( ) or prevents ( ) any configuration of the
transmitter. Default security is off ( ).
Use the following procedure to change the switch configuration:
Procedure
1. If the transmitter is installed, secure the loop, and remove power.
2. Remove the housing cover opposite the field terminal side. Do not
remove the instrument cover in explosive atmospheres when the
circuit is live.
3. Slide the security and alarm switches into the preferred position
using a small screwdriver.
4. Reattach the transmitter cover. The cover must be fully engaged to
comply with explosion-proof requirements.
