Rosemount 3051N

6-8

Option PM is a SST pipe mount bracket assembly designed for use in pipe 
mounting the Traditional Flange (H2). It is the same bracket used on other 
RNII nuclear qualified transmitters, including the Rosemount 1154 Series H.

When installing the transmitter to the optional mounting brackets, torque the 
bolts to 21 foot-pounds. See “Mounting” in Section 3 for additional mounting 
considerations.

Traditional Flange (H2)

The traditional flange option converts the mounting configuration of the 
Rosemount 3051N to one similar to traditional style transmitters. This allows 
the Rosemount 3051N to replace traditional transmitters without changing 
existing manifolds, impulse piping, or bracket arrangements. The traditional 
flange also allows a higher process temperature at the process ports (300 °F 
[149 °C]) because of its ability to dissipate heat. 

The traditional flange fits most existing mounting brackets. If a new bracket is 
required, use one of the bracket options described earlier. Figure 6-3 in 
Section 6 shows the traditional flange.

TRANSIENT 
PROTECTION TERMINAL 
BLOCK (T1)

The standard transient protection terminal block increases the Rosemount 
3051N Pressure Transmitter’s ability to withstand electrical transients. 
Rosemount 3051N Pressure Transmitters, with integral transient protection 
installed, meet the standard performance specifications as outlined in this 
product manual.

Installation of the transient protection terminal block does not provide 
transient protection unless the Rosemount 3051N transmitter case is properly 
grounded. See Section 3 for grounding information.
