OVERVIEW This section is designed to guide you through a successful Rosemount 2088,
2090F, or 2090P Transmitter installation. Starting with an installation
flowchart, this section contains information on installation considerations and
transmitter options. Dimensional drawings are also included in this section.
SAFETY MESSAGES Instructions and procedures in this section may require special precautions to
ensure the safety of the personnel performing the operations. Information that
raises potential safety issues is indicated by a warning symbol ( ). Please
refer to the following safety messages before performing an operation
preceded by this symbol.

Warnings
Explosions could result in death or serious injury:
• Do not remove the transmitter cover in explosive atmospheres
when the circuit is alive.
• 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.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
• Both transmitter covers must be fully engaged to meet
explosion-proof requirements.
Failure to follow these installation guidelines could result in death or serious injury:
• Make sure only qualified personnel perform the installation.

High voltage that may be present on leads could cause electrical shock:
• Avoid contact with leads and terminals.
Use appropriately rated sanitary clamps and gaskets during installation. The
maximum working pressure of the clamp and gasket must be greater than or equal to
the working pressure range of the transmitter. Failure to use proper clamps and
gaskets can cause process leaks and can result in death or serious injury.

GENERAL
CONSIDERATIONS
ENVIRONMENTAL
CONSIDERATIONS
The accuracy of the pressure measurement depends on proper installation of
the transmitter and impulse piping. The piping between the process and
transmitter must accurately transmit pressure to the transmitter. Mount the
transmitter close to the process and use a minimum of impulse piping to
achieve the best accuracy. Keep in mind, however, the need for convenient
access, safety of personnel, practical field calibration, and a suitable
transmitter environment. In general, install the transmitter to minimize
vibration, shock, and temperature fluctuations.
Do not apply torque directly to the electronics housing. Rotation between the electronics
housing and the process connection can damage the electronics. To avoid damage, apply
torque only to the hex-shaped process connection. Use a backup wrench on Process
Connection when installing an adapter.
Temperature
Mount the transmitter in a manner that minimizes variations in ambient
temperature.
Moisture and Corrosives The transmitter is designed to resist attack by moisture and corrosives. The
electronics module is fully encapsulated and mounted in a compartment that
is sealed from the power-side conduit entries. O-ring seals protect both
compartments when the covers are installed.
In humid environments, it is possible for moisture to accumulate in the conduit
lines and reach the terminal compartment of the transmitter housing. To
prevent moisture from entering the terminal compartment, mount the
transmitter at a high point in the conduit run, if possible. Also, remove the
terminal compartment cover periodically and inspect the terminals for
moisture and corrosion.
Hazardous Locations
Installations
Rosemount 2088, 2090P, and 2090F transmitters are designed with
explosion-proof electronics enclosures and circuitry that complies with
intrinsic safety requirements and non-incendive operation. Individual
transmitters are clearly tagged with approvals. Refer to Section 5:
Specifications and Reference Data for a complete list of available approvals.
To maintain certified ratings for installed transmitters, install with applicable
installation codes and approval drawings.
NOTE
Once a device labeled with multiple approval types is installed, it should not
be reinstalled using any other approval types. Permanently mark the approval
label to distinguish it from unused approval types.

MECHANICAL CONSIDERATIONS
Mounting
Rosemount 2088 The Rosemount 2088 Smart Transmitter weighs approximately 2.44 lb.
(1,11 kg). The 2088 Analog Transmitter weighs approximately 1.9 lb.
(0,86 kg). In many cases, its compact size and light weight makes it possible
to mount the 2088 directly to the impulse line without using an additional
mounting bracket. When this is not desirable, mount directly to a wall, panel,
or two-inch pipe using the optional mounting bracket (see Figure 3-3).
The 2088 also offers several process connections. Use your plant-approved
thread sealant to ensure a leak-proof connection.
Rosemount 2090P The Rosemount 2090P is designed to be mounted directly to the process pipe
using a weld spud (see Figure 3-7). Mount the transmitter using an existing
weld spud, or install a new one using the instructions on page -9.
Rosemount 2090F The Rosemount 2090F is designed to be mounted directly to the process pipe
using a standard sanitary fitting (see Figure 3-8). The transmitter is available
with either a 1.5- or 2-inch Tri-Clamp
®
connection.
