2 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 2-1).
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.

2.5 Trim the transmitter
Devices are calibrated by the factory. Once installed, it is recommended to
perform a zero trim on gage transmitter to eliminate error due to mounting
position or static pressure effects. A zero trim can be performed using either a
Field Communicator or configuration buttons.
Note
When performing a zero trim, ensure the equalization valve is open and all
wet legs are filled to the correct level.
CAUTION
It is not recommended to zero an absolute transmitter, Rosemount 3051HTA
model.
Procedure
Choose your trim procedure.
a) Analog zero trim – Sets the analog output to 4 mA.
•Also referred to as a “rerange” it sets the lower range value (LRV)
equal to the measured pressure.
•The display and digital HART output remains unchanged.
b) Digital zero trim – Recalibrates the sensor zero.
•The LRV is unaffected. The pressure value will be zero (on display
and HART output). 4 mA point may not be at zero.
•This requires the factory calibrated zero pressure is within a range
of 3% of the URL [0 ± 3% × URL].
Example
URV = 250 inH2O
Quick Start Guide February 2019
14 Emerson.com/Rosemount

Applied Zero Pressure = ± 0.03× 250 inH2O = ± 7.5 inH2O (compared to
factory settings) values outside this range will be rejected by the transmitter
2.5.1 Trimming with a Field Communicator
Procedure
1. Connect the Field Communicator, see Connect the wiring and power
up for instructions.
2. Follow the HART menu to perform the desired zero trim.
