Transmitter installation

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 water/dust tight 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 gage 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
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.
