Rosemount™ 3051HT Hygienic Pressure
Transmitter
with FOUNDATION™ Fieldbus Protocol
NOTICE
This guide provides basic guidelines for the Rosemount 3051HT Transmitter. It does not provide
instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-proof,
Flameproof, or intrinsically safe (I.S.) installations.
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.
In an explosion-proof/flameproof installation, do not remove the transmitter covers when power is
applied to the unit.
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.
Process leaks could result in death or serious injury.
To avoid process leaks, only use the gasket designed to seal with the corresponding flange adapter.ph>
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.
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.

2 Transmitter installation
Figure 2-1: Installation Flowchart
2.1 Mount the transmitter
Place the transmitter to the desired orientation before mounting.
Transmitter must not be securely mounted or clamped in place when
changing transmitter orientation.
Conduit entry orientation
When installing a Rosemount 3051HT, it is recommended installing so a
conduit entry faces downward or parallel to the ground to maximize
drainability when cleaning.
Environmental seal for housing
Thread sealing (PTFE) tape or paste on male threads of conduit is required to
provide a watertight/dustproof conduit seal and meets requirements of
NEMA® Type 4X, IP66, IP68, and IP69K. Consult factory if other Ingress
Protection ratings are required.
Note
IP69K rating only available on units with a SST housing and option code V9 in
the model string.
For M20 threads, install conduit plugs to full thread engagement or until
mechanical resistance is met.
In-line gauge transmitter orientation
The low side pressure port (atmospheric reference) on the in-line gage
transmitter is located on the neck of the transmitter via a protected gage
vent (See Figure 2-2).
Keep the vent path free from obstructions including but not limited to paint,
dust, and viscous fluids by mounting the transmitter so the process can drain
away.

Clamping
When installing clamp, follow recommended torque values provided by
gasket manufacturer.
Note
To maintain performance, torquing a 1.5-in. Tri Clamp beyond 50 in-lb. is
not recommended on pressure ranges below 20 psi.

2.2 Commissioning (paper) tag
To identify which device is at a particular location use the removable tag
provided with the transmitter. Ensure the physical device tag (PD Tag field)
is properly entered in both places on the removable commissioning tag and
tear off the bottom portion for each transmitter.

2.3.1 Setting the security switch
The security switch allows ( ) or prevents ( ) any configuration of the
transmitter.
Note
Default security is off ( ).
Setting the simulate switch
The security switch can be enabled or disabled in the software.
Procedure
1. If the transmitter is installed, secure the loop, and remove power.
2. Remove the housing cover opposite the field terminal side.
WARNING
Explosions could result in death or serious injury.
In an explosion-proof/flameproof installation, do not remove the
transmitter covers when power is applied to the unit.

Quick Start Guide 7
3. Slide the security switch into the preferred position.
4. Reattach the transmitter housing cover.
Tighten the cover until there is no gap between the cover and
housing to comply with explosion proof requirements.
2.3.2 Setting the simulate switch
The simulate switch is used in conjunction with the transmitter simulate
software to simulate process variables and/or alerts and alarms.
Note
The simulate switch enables or disables simulated alerts and simulated AI
Block status and values. The default simulate switch position is enabled.
•To simulate variables and/or alerts and alarms, the simulate switch must
be moved to the enable position and the software enabled through the
host before installation of the transmitter.
•To disable simulation, the switch must be in the disable position or the
software simulate parameter must be disabled through the host.
Procedure
1. If the transmitter is installed, secure the loop, and remove power.
2. Remove the housing cover opposite the field terminal side.
WARNING
Explosions could result in death or serious injury.
In an explosion-proof/flameproof installation, do not remove the
transmitter covers when power is applied to the unit.
3. Slide the simulate switch into the preferred position.
4. Reattach the transmitter housing cover.
Tighten the cover until there is no gap between the cover and
housing to comply with explosion proof requirements.
2.4 Connect the wiring and power up
Procedure to connect the wiring and power up the transmitter.
Prerequisites
•Use copper wire of sufficient size to ensure the voltage across the
transmitter power terminals does not drop below 9 Vdc. A minimum of
12 Vdc under normal operating conditions is recommended. Shielded
twisted pair Type A cable is recommended.
Quick Start Guide June 2020
8 Emerson.com/Rosemount
•Power supply voltage can be variable, especially under abnormal
conditions such as when operating on battery backup.
Procedure
1. To power the transmitter, connect the power leads to the terminals
indicated on the terminal block label.
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, terminal polarity should be followed.
When wiring to the screw terminals, the use of crimped legs is
recommended.
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. No additional power
is needed.
Note
The use of a pin or a ferrule wire terminal is not recommended as the
connection may be more susceptible to loosening over time or under
vibration.
3. Ensure proper grounding. It is important 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.
4. If transient protection is needed, refer to section Signal ground
wiring for grounding instructions.
5. Plug and seal unused conduit connections.
6. Reattach the transmitter covers.
a) The covers must only be capable of being released or
removed with the aid of a tool to comply with applicable
ordinary locations requirements.

2.4.1 Signal ground wiring
Do not run signal wiring in conduit or open trays with power wiring, or near
heavy electrical equipment. Grounding terminations are provided on the
outside of the electronics housing and inside the Terminal Compartment.
These grounds are used when transient protect terminal blocks are installed
or to fulfill local regulations.
Procedure
1. Remove the field terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 2-5
a) Trim the cable shield as short as practical and insulate from
touching the transmitter housing.
Note
Do NOT ground the cable shield at the transmitter; if the
cable shield touches the transmitter housing, it can create
ground loops and interfere with communications.
b) Continuously connect the cable shields to the power supply
ground.
c) Connect the cable shields for the entire segment to a single
good earth ground at the power supply.
