1 About this guide
This guide provides basic guidelines for Rosemount 2051 Pressure
Transmitters. It does not provide instructions for configuration,
diagnostics, maintenance, service, troubleshooting, explosionproof,
flameproof, or intrinsically safe (I.S.) installations. Refer to the
Rosemount 2051 Pressure Transmitter Reference Manual for
more instructions. This guide is also available electronically at
Emerson.com.
1.1 Safety messages
WARNING
Explosions could result in death or serious injury.
Installation of these transmitters 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 2051 Reference Manual for any restrictions
associated with a safe installation.
In an explosionproof/flameproof installation, do not remove the
transmitter covers when power is applied to the transmitter.
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 marked, the conduit/cable entries in the housing use a ½–14
NPT thread form. 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.

WARNING
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 in 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 System readiness
Note
Before installing the transmitter, confirm the correct device driver is
loaded on the host systems.
2.1 Confirm correct device driver
•Verify the correct device driver (DD/DTM™) is loaded on your
systems to ensure proper communications.
•Download the correct device driver at your host vendor download
site, Emerson.com/DeviceInstallKits, or FieldCommGroup.org.
2.1.1 Device revisions and drivers
Table 2-1 provides the information necessary to ensure you have the
correct device driver and documentation for your device.

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 3-1. If bolt material is not shown in Table 3-1,
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 any additional lubricant when installing either type of bolt.
Procedure
1. Tighten the bolts by hand.
2. Torque the bolts to the initial torque value using a crossing
pattern.
See Table 3-1 for initial torque value.
3. Torque the bolts to the final torque value using the same
crossing pattern.
See Table 3-1 for final torque value.
