Model 2088 Low Power
Current procedures for installing, configuring, and maintaining the
Model 2088 Smart Low-Power transmitter are identical to the Model
2088 Smart transmitter with 4-20 mA output, see manual
00809-0100-4690.
The current wiring diagram and Model 275 HART fast-key sequences
for the Model 2088 Low Power option are shown below.
Mount the transmitter
The following are approximate weights of each transmitter:
Rosemount 2088 2.44 lb (1,11 kg)
Rosemount 2090F 2.74 lb (1.24 kg)
Rosemount 2090P 2.96 lb (1.34 kg).
In many cases its compact size and light weight makes it possible
to mount directly to the respective apparatus 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
Electronics housing clearance
Mount the transmitter so the terminal side is accessible. Clearance
of 0.75-in. (19 mm) is required for cover removal. Use a conduit
plug in the unused conduit opening. Three inches of clearance is
required for cover removal if a meter is installed.
Environmental seal for housing
Thread sealing (PTFE) tape or paste on male threads of conduit is
required to provide a water/dust tight conduit seal 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.
Mounting brackets
Rosemount 2088, 2090F, or 2090P transmitters may be panel-mounted
or pipe-mounted via an optional mounting bracket (option code B4).
See Figure 3-1 on page 32 and for dimensional and mounting
configuration information.
Configuring transmitter security
There are four security methods with the Rosemount 2088, 2090F, and
2090P transmitters.
